備註

使用這個多載來啟動進程資源,並將它與目前Process的元件產生關聯。Use this overload to start a process resource and associate it with the current Process component. 傳回值true表示新的進程資源已啟動。The return value true indicates that a new process resource was started. 如果FileName StartInfo屬性(property)成員指定的進程資源已在電腦上執行,則不會啟動任何額外的進程資源。If the process resource specified by the FileName member of the StartInfo property is already running on the computer, no additional process resource is started. 相反地,會重複使用執行中的false進程資源並傳回。Instead, the running process resource is reused and false is returned.

您可以藉由指定原先用來安裝應用程式的位置(例如,網址)來啟動 ClickOnce 應用程式。You can start a ClickOnce application by specifying the location (for example, a Web address) from which you originally installed the application. 請不要在您的硬碟上指定安裝的位置來啟動 ClickOnce 應用程式。Do not start a ClickOnce application by specifying its installed location on your hard drive.

注意

如果您使用 Visual Studio,則在Start Process將元件拖曳至設計工具之後,會將此方法的多載插入程式碼中。If you are using Visual Studio, this overload of the Start method is the one that you insert into your code after you drag a Process component onto the designer. 使用視窗展開類別目錄,並將適當FileName的值寫入屬性中。 StartInfo PropertiesUse the Properties window to expand the StartInfo category and write the appropriate value into the FileName property. 您的變更將會出現在窗InitializeComponent體的程式中。Your changes will appear in the form's InitializeComponent procedure.

Start這個多載static不是方法。This overload of Start is not a static method. 您必須從Process類別的實例呼叫它。You must call it from an instance of the Process class. 在呼叫Start之前,您必須先StartInfo指定這個Process實例的屬性資訊,因為該資訊是用來判斷要啟動的進程資源。Before calling Start, you must first specify StartInfo property information for this Process instance, because that information is used to determine the process resource to start.

Start方法的其他多載是static成員。The other overloads of the Start method are static members. 在呼叫方法的多載之前,您不Process需要建立元件的實例。You do not need to create an instance of the Process component before you call those overloads of the method. 相反地,您可以Start呼叫Process類別本身,並在進程啟動Process時建立新的元件。Instead, you can call Start for the Process class itself, and a new Process component is created if the process was started. 或者, null如果已重複使用進程,則會傳回。Or, null is returned if a process was reused. 進程資源會自動與Process Start方法所傳回的新元件產生關聯。The process resource is automatically associated with the new Process component that is returned by the Start method.

成員可以用來複製 Windows Start功能表之Run對話方塊的功能。 StartInfoThe StartInfo members can be used to duplicate the functionality of the Run dialog box of the Windows Start menu. 您可以在StartInfo屬性中設定適當的值,以啟動可輸入命令列的任何專案。Anything that can be typed into a command line can be started by setting the appropriate values in the StartInfo property. 唯一StartInfo必須設定的屬性FileName是屬性。The only StartInfo property that must be set is the FileName property. FileName屬性不一定要是可執行檔。The FileName property does not have to be an executable file. 它可以是任何副檔名已與系統上安裝之應用程式相關聯的檔案類型。It can be of any file type for which the extension has been associated with an application that is installed on the system. 例如,如果您FileName有與編輯器相關聯的文字檔(例如 [記事本]),則屬性的副檔名可以是 .txt,如果您有相關聯的 .doc 檔案與文字處理工具(例如 Microsoft word),它可能會有 .doc 副檔名。For example, the FileName property can have a .txt extension if you have associated text files with an editor, such as Notepad, or it can have a .doc extension if you have associated.doc files with a word processing tool, such as Microsoft Word.

在命令列中,您可以指定要對特定類型的檔案採取的動作。In the command line, you can specify actions to take for certain types of files. 例如,您可以列印檔案或編輯文字檔。For example, you can print documents or edit text files. 使用Verb StartInfo屬性的成員來指定這些動作。Specify these actions using the Verb member of the StartInfo property. 對於其他類型的檔案,當您從Run對話方塊啟動檔案時,可以指定命令列引數。For other types of files, you can specify command-line arguments when you start the file from the Run dialog box. 例如,如果您將瀏覽器指定為FileName,則可以將 URL 當做引數傳遞。For example, you can pass a URL as an argument if you specify your browser as the FileName. 這些引數可在StartInfo屬性的Arguments成員中指定。These arguments can be specified in the StartInfo property's Arguments member.

如果您在系統中使用引號宣告了 path 變數,則在啟動該位置中找到的任何進程時,必須完整限定該路徑。If you have a path variable declared in your system using quotes, you must fully qualify that path when starting any process found in that location. 否則,系統將找不到路徑。Otherwise, the system will not find the path. 例如,如果c:\mypath不在您的路徑中,而且您使用引號來加入它: path = %path%;"c:\mypath",則在啟動它時,您c:\mypath必須完整限定中的任何程式。For example, if c:\mypath is not in your path, and you add it using quotation marks: path = %path%;"c:\mypath", you must fully qualify any process in c:\mypath when starting it.

注意

ASP.NET 網頁和伺服器控制項程式碼會在 Web 服務器上的 ASP.NET worker 進程內容中執行。ASP.NET Web page and server control code executes in the context of the ASP.NET worker process on the Web server. 如果您使用 ASP.NET Start網頁或伺服器控制項中的方法,新的進程會在具有限制許可權的 Web 服務器上執行。If you use the Start method in an ASP.NET Web page or server control, the new process executes on the Web server with restricted permissions. 進程不會在與用戶端瀏覽器相同的內容中啟動,也無法存取使用者桌面。The process does not start in the same context as the client browser, and does not have access to the user desktop.

每當您使用Start來啟動處理常式時,可能需要關閉它或遺失系統資源的風險。Whenever you use Start to start a process, you might need to close it or you risk losing system resources. 使用CloseMainWindowKill關閉處理常式。Close processes using CloseMainWindow or Kill. 您可以使用其HasExited屬性來檢查進程是否已關閉。You can check whether a process has already been closed by using its HasExited property.

這裡有關于受控執行緒中的公寓狀態的注意事項。A note about apartment states in managed threads is necessary here. UseShellExecute位於StartInfo main()進程元件的屬性時,請確定您已透過在方法上設定屬性[STAThread] ,在應用程式上設定執行緒模型。 trueWhen UseShellExecute is true on the process component's StartInfo property, make sure you have set a threading model on your application by setting the attribute [STAThread] on the main() method. 否則, unknown managed 執行緒可以處於狀態或進入MTA狀態,後者會與UseShellExecute true發生衝突。Otherwise, a managed thread can be in an unknown state or put in the MTA state, the latter of which conflicts with UseShellExecute being true. 某些方法需要單元狀態不是unknownSome methods require that the apartment state not be unknown. 如果未明確設定狀態,當應用程式遇到這種方法時,它會預設為MTA,且一旦設定,就無法變更單元狀態。If the state is not explicitly set, when the application encounters such a method, it defaults to MTA, and once set, the apartment state cannot be changed. 不過, MTA當作業系統 shell 管理執行緒時,會導致擲回例外狀況。However, MTA causes an exception to be thrown when the operating system shell is managing the thread.

ProcessStartInfo,包含用來啟動處理序的資訊,包括檔名和任何命令列引數。The ProcessStartInfo that contains the information that is used to start the process, including the file name and any command-line arguments.

傳回

與處理程序資源關聯的新 Process,或者是 null (若未啟動任何處理程序資源)。A new Process that is associated with the process resource, or null if no process resource is started. 請注意,隨著已在執行中之相同處理程序啟動的新處理程序將獨立於其他處理程序之外。Note that a new process that's started alongside already running instances of the same process will be independent from the others. 此外,啟動可能會傳回非空值處理程序,且其 HasExited 屬性會設定為 trueIn addition, Start may return a non-null Process with its HasExited property already set to true. 在此案例中,已啟動的處理程序可能已啟用本身的現有執行個體並結束。In this case, the started process may have activated an existing instance of itself and then exited.

例外狀況

startInfo 參數的 FileName 屬性沒有指定任何檔案名稱。No file name was specified in the startInfo parameter's FileName property.

-或--or- startInfo 參數的 UseShellExecute 屬性是 true,而 RedirectStandardInputRedirectStandardOutputRedirectStandardError 屬性也是 trueThe UseShellExecute property of the startInfo parameter is true and the RedirectStandardInput, RedirectStandardOutput, or RedirectStandardError property is also true.

-或--or- startInfo 參數的 UseShellExecute 屬性是 true,而 UserName 屬性不是 null 或空白,或者 Password 屬性不是 nullThe UseShellExecute property of the startInfo parameter is true and the UserName property is not null or empty or the Password property is not null.

引數長度和處理序完整路徑長度的總和超過 2080。The sum of the length of the arguments and the length of the full path to the process exceeds 2080. 與此例外狀況建立關聯的錯誤訊息可以是下列其中一項:「傳遞到系統呼叫的資料區域太小。」The error message associated with this exception can be one of the following: "The data area passed to a system call is too small." 或「拒絕存取」。or "Access is denied."

此方法在沒有殼層支援的作業系統上不受支援,例如 Nano 伺服器 (僅限 .NET Core)。Method not supported on operating systems without shell support such as Nano Server (.NET Core only).

範例

下列範例會先產生 Internet Explorer 的實例,並在瀏覽器中顯示 [我的最愛] 資料夾的內容。The following example first spawns an instance of Internet Explorer and displays the contents of the Favorites folder in the browser. 接著,它會啟動一些其他的 Internet Explorer 實例,並顯示某些特定的頁面或網站。It then starts some other instances of Internet Explorer and displays some specific pages or sites. 最後,它會啟動 Internet Explorer,並在流覽至特定網站時,將視窗最小化。Finally it starts Internet Explorer with the window being minimized while navigating to a specific site.

備註

您可以使用這個多載,藉由指定ProcessStartInfo實例來啟動進程資源。Use this overload to start a process resource by specifying a ProcessStartInfo instance. 多載會將資源與新Process的物件產生關聯。The overload associates the resource with a new Process object.

注意

如果要啟動之可執行檔的位址是 URL,則不會啟動該進程, null而且會傳回。If the address of the executable file to start is a URL, the process is not started and null is returned.

這個多載可讓您在沒有先建立新Process實例的情況下啟動進程。This overload lets you start a process without first creating a new Process instance. 將這個多載與ProcessStartInfo參數搭配使用,是建立新Process實例、設定其屬性,以及呼叫Start Process實例StartInfo之明確步驟的替代方法。Using this overload with a ProcessStartInfo parameter is an alternative to the explicit steps of creating a new Process instance, setting its StartInfo properties, and calling Start for the Process instance.

使用實例做為參數可讓您呼叫Start ,而對傳遞至呼叫來啟動處理常式的作業具有最大的控制權。 ProcessStartInfoUsing a ProcessStartInfo instance as the parameter lets you call Start with the most control over what is passed into the call to start the process. 如果您只需要傳遞檔案名或檔案名和引數,則不需要建立新ProcessStartInfo的實例,但這是一個選項。If you need to pass only a file name or a file name and arguments, it is not necessary to create a new ProcessStartInfo instance, although that is an option. 唯一Process.StartInfo必須設定的屬性FileName是屬性。The only Process.StartInfo property that must be set is the FileName property. FileName屬性不需要代表可執行檔。The FileName property does not need to represent an executable file. 它可以是任何副檔名已與系統上安裝之應用程式相關聯的檔案類型。It can be of any file type for which the extension has been associated with an application that is installed on the system. 例如,如果您FileName有與編輯器相關聯的文字檔(例如 [記事本]),則屬性的副檔名可以是 .txt,如果您有相關聯的 .doc 檔案與文字處理工具(例如 Microsoft word),它可能會有 .doc 副檔名。For example, the FileName property can have a .txt extension if you have associated text files with an editor, such as Notepad, or it can have a .doc extension if you have associated.doc files with a word processing tool, such as Microsoft Word.

您可以藉由指定原先用來安裝應用程式的位置(例如,網址)來啟動 ClickOnce 應用程式。You can start a ClickOnce application by specifying the location (for example, a Web address) from which you originally installed the application. 請不要在您的硬碟上指定安裝的位置來啟動 ClickOnce 應用程式。Do not start a ClickOnce application by specifying its installed location on your hard drive.

如果設定ProcessStartInfo.UserName StartInfo實例ProcessStartInfo.Password的和屬性,則會呼叫非受控CreateProcessWithLogonW函式, ProcessStartInfo.CreateNoWindow這會在新視窗中啟動進程,即使屬性值為trueProcessStartInfo.WindowStyle屬性值為ProcessWindowStyle.HiddenIf the ProcessStartInfo.UserName and ProcessStartInfo.Password properties of the StartInfo instance are set, the unmanaged CreateProcessWithLogonW function is called, which starts the process in a new window even if the ProcessStartInfo.CreateNoWindow property value is true or the ProcessStartInfo.WindowStyle property value is ProcessWindowStyle.Hidden. @ null ProcessStartInfo.UserName 如果屬性為,則屬性必須是 UPN 格式,也就是使用者 DNS_domain_name。 ProcessStartInfo.DomainIf the ProcessStartInfo.Domain property is null, the ProcessStartInfo.UserName property must be in UPN format, user@DNS_domain_name.

與其他多載不同的是, Start沒有參數的多載static不是成員。Unlike the other overloads, the overload of Start that has no parameters is not a static member. 當您已經建立實例、指定了Process開始資訊(包括檔案名),而且想要啟動進程資源,並將它與現有Process的實例產生關聯時,請使用該多載。Use that overload when you have already created a Process instance, specified start information (including the file name), and want to start a process resource and associate it with the existing Process instance. 當您想要static建立新Process的元件,而不是啟動現有元件的進程時,請使用其中一個多載。Use one of the static overloads when you want to create a new Process component rather than start a process for an existing component. 此多載和沒有參數的多載,可讓您使用ProcessStartInfo實例來指定進程資源的啟動資訊。Both this overload and the overload that has no parameters allow you to specify the start information for the process resource by using a ProcessStartInfo instance.

如果您在系統中使用引號宣告了 path 變數,則在啟動該位置中找到的任何進程時,必須完整限定該路徑。If you have a path variable declared in your system using quotes, you must fully qualify that path when starting any process found in that location. 否則,系統將找不到路徑。Otherwise, the system will not find the path. 例如,如果c:\mypath不在您的路徑中,而且您使用引號來加入它: path = %path%;"c:\mypath",則在啟動它時,您c:\mypath必須完整限定中的任何程式。For example, if c:\mypath is not in your path, and you add it using quotation marks: path = %path%;"c:\mypath", you must fully qualify any process in c:\mypath when starting it.

注意

ASP.NET 網頁和伺服器控制項程式碼會在 Web 服務器上的 ASP.NET worker 進程內容中執行。ASP.NET Web page and server control code executes in the context of the ASP.NET worker process on the Web server. 如果您使用 ASP.NET Start網頁或伺服器控制項中的方法,新的進程會在具有限制許可權的 Web 服務器上執行。If you use the Start method in an ASP.NET Web page or server control, the new process executes on the Web server with restricted permissions. 進程不會在與用戶端瀏覽器相同的內容中啟動,也無法存取使用者桌面。The process does not start in the same context as the client browser, and does not have access to the user desktop.

每當您使用Start來啟動處理常式時,可能需要關閉它或遺失系統資源的風險。Whenever you use Start to start a process, you might need to close it or you risk losing system resources. 使用CloseMainWindowKill關閉處理常式。Close processes using CloseMainWindow or Kill. 您可以使用其HasExited屬性來檢查進程是否已關閉。You can check whether a process has already been closed by using its HasExited property.

這裡有關于受控執行緒中的公寓狀態的注意事項。A note about apartment states in managed threads is necessary here. UseShellExecute位於true main()參數上[STAThread]時,請確定您已透過在方法上設定屬性,在應用程式上設定執行緒模型。 startInfoWhen UseShellExecute is true on the startInfo parameter, make sure you have set a threading model on your application by setting the attribute [STAThread] on the main() method. 否則, unknown managed 執行緒可以處於狀態或進入MTA狀態,後者會與UseShellExecute true發生衝突。Otherwise, a managed thread can be in an unknown state or put in the MTA state, the latter of which conflicts with UseShellExecute being true. 某些方法需要單元狀態不是unknownSome methods require that the apartment state not be unknown. 如果未明確設定狀態,當應用程式遇到這種方法時,它會預設為MTA,且一旦設定,就無法變更單元狀態。If the state is not explicitly set, when the application encounters such a method, it defaults to MTA, and once set, the apartment state cannot be changed. 不過, MTA當作業系統 shell 管理執行緒時,會導致擲回例外狀況。However, MTA causes an exception to be thrown when the operating system shell is managing the thread.

備註

您可以使用這個多載來啟動進程資源,方法是指定其檔案名。Use this overload to start a process resource by specifying its file name. 多載會將資源與新Process的物件產生關聯。The overload associates the resource with a new Process object.

注意

如果要啟動之可執行檔的位址是 URL,則不會啟動該進程, null而且會傳回。If the address of the executable file to start is a URL, the process is not started and null is returned.

這個多載可讓您在沒有先建立新Process實例的情況下啟動進程。This overload lets you start a process without first creating a new Process instance. Process載是建立新實例、 FileName設定StartInfo屬性的成員,以及呼叫Start Process實例之明確步驟的替代方法。The overload is an alternative to the explicit steps of creating a new Process instance, setting the FileName member of the StartInfo property, and calling Start for the Process instance.

您可以藉由將fileName參數設定為您原先安裝應用程式的位置(例如,網址)來啟動 ClickOnce 應用程式。You can start a ClickOnce application by setting the fileName parameter to the location (for example, a Web address) from which you originally installed the application. 請不要在您的硬碟上指定安裝的位置來啟動 ClickOnce 應用程式。Do not start a ClickOnce application by specifying its installed location on your hard drive.

藉由指定檔案名來啟動處理常式,類似于在 Windows Run Start功能表的對話方塊中輸入資訊。Starting a process by specifying its file name is similar to typing the information in the Run dialog box of the Windows Start menu. 因此,檔案名不需要代表可執行檔。Therefore, the file name does not need to represent an executable file. 它可以是與系統上安裝之應用程式相關聯的任何檔案類型。It can be of any file type for which the extension has been associated with an application installed on the system. 例如,如果您有與編輯器相關聯的文字檔(例如 [記事本]),檔案名的副檔名可以是 .txt,或者如果您有相關聯的 .doc 檔案與文字處理工具(例如 Microsoft Word),它可能會有 .doc。For example the file name can have a .txt extension if you have associated text files with an editor, such as Notepad, or it can have a .doc if you have associated.doc files with a word processing tool, such as Microsoft Word. 同樣地,如同Run對話方塊可以接受包含或不含 .exe 副檔名的可執行檔名稱一樣,在fileName參數中,.exe 副檔名是選擇性的。Similarly, in the same way that the Run dialog box can accept an executable file name with or without the .exe extension, the .exe extension is optional in the fileName parameter. 例如,您可以將fileName參數設定為 "notepad.exe" 或 "notepad"。For example, you can set the fileName parameter to either "Notepad.exe" or "Notepad".

這個多載不允許處理常式的命令列引數。This overload does not allow command-line arguments for the process. 如果您需要為進程指定一或多個命令列引數,請使用Process.Start(ProcessStartInfo)Process.Start(String, String)多載。If you need to specify one or more command-line arguments for the process, use the Process.Start(ProcessStartInfo) or Process.Start(String, String) overloads.

與其他多載不同的是, Start沒有參數的多載static不是成員。Unlike the other overloads, the overload of Start that has no parameters is not a static member. 當您已經建立實例、指定了Process開始資訊(包括檔案名),而且想要啟動進程資源,並將它與現有Process的實例產生關聯時,請使用該多載。Use that overload when you have already created a Process instance, specified start information (including the file name), and want to start a process resource and associate it with the existing Process instance. 當您想要static建立新Process的元件,而不是啟動現有元件的進程時,請使用其中一個多載。Use one of the static overloads when you want to create a new Process component rather than start a process for an existing component. 此多載和沒有參數的多載,可讓您指定要啟動之進程資源的檔案名。Both this overload and the overload that has no parameters allow you to specify the file name of the process resource to start.

如果您在系統中使用引號宣告了 path 變數,則在啟動該位置中找到的任何進程時,必須完整限定該路徑。If you have a path variable declared in your system using quotes, you must fully qualify that path when starting any process found in that location. 否則,系統將找不到路徑。Otherwise, the system will not find the path. 例如,如果c:\mypath不在您的路徑中,而且您使用引號來加入它: path = %path%;"c:\mypath",則在啟動它時,您c:\mypath必須完整限定中的任何程式。For example, if c:\mypath is not in your path, and you add it using quotation marks: path = %path%;"c:\mypath", you must fully qualify any process in c:\mypath when starting it.

注意

ASP.NET 網頁和伺服器控制項程式碼會在 Web 服務器上的 ASP.NET worker 進程內容中執行。ASP.NET Web page and server control code executes in the context of the ASP.NET worker process on the Web server. 如果您使用 ASP.NET Start網頁或伺服器控制項中的方法,新的進程會在具有限制許可權的 Web 服務器上執行。If you use the Start method in an ASP.NET Web page or server control, the new process executes on the Web server with restricted permissions. 進程不會在與用戶端瀏覽器相同的內容中啟動,也無法存取使用者桌面。The process does not start in the same context as the client browser, and does not have access to the user desktop.

每當您使用Start來啟動處理常式時,可能需要關閉它或遺失系統資源的風險。Whenever you use Start to start a process, you might need to close it or you risk losing system resources. 使用CloseMainWindowKill關閉處理常式。Close processes using CloseMainWindow or Kill. 您可以使用其HasExited屬性來檢查進程是否已關閉。You can check whether a process has already been closed by using its HasExited property.

這裡有關于受控執行緒中的公寓狀態的注意事項。A note about apartment states in managed threads is necessary here. UseShellExecute位於StartInfo main()進程元件的屬性時,請確定您已透過在方法上設定屬性[STAThread] ,在應用程式上設定執行緒模型。 trueWhen UseShellExecute is true on the process component's StartInfo property, make sure you have set a threading model on your application by setting the attribute [STAThread] on the main() method. 否則, unknown managed 執行緒可以處於狀態或進入MTA狀態,後者會與UseShellExecute true發生衝突。Otherwise, a managed thread can be in an unknown state or put in the MTA state, the latter of which conflicts with UseShellExecute being true. 某些方法需要單元狀態不是unknownSome methods require that the apartment state not be unknown. 如果未明確設定狀態,當應用程式遇到這種方法時,它會預設為MTA,且一旦設定,就無法變更單元狀態。If the state is not explicitly set, when the application encounters such a method, it defaults to MTA, and once set, the apartment state cannot be changed. 不過, MTA當作業系統 shell 管理執行緒時,會導致擲回例外狀況。However, MTA causes an exception to be thrown when the operating system shell is managing the thread.

備註

您可以使用這個多載來啟動進程資源,方法是指定其檔案名和命令列引數。Use this overload to start a process resource by specifying its file name and command-line arguments. 多載會將資源與新Process的物件產生關聯。The overload associates the resource with a new Process object.

注意

如果要啟動之可執行檔的位址是 URL,則不會啟動該進程, null而且會傳回。If the address of the executable file to start is a URL, the process is not started and null is returned.

這個多載可讓您在沒有先建立新Process實例的情況下啟動進程。This overload lets you start a process without first creating a new Process instance. 多載是Process建立新實例、設定StartInfo屬性的FileNameArguments成員,以及呼叫Start Process實例之明確步驟的替代方法。The overload is an alternative to the explicit steps of creating a new Process instance, setting the FileName and Arguments members of the StartInfo property, and calling Start for the Process instance.

藉由指定檔案的檔案名和引數來啟動進程,類似于在 Windows Run Start功能表的對話方塊中輸入檔案名和命令列引數。Starting a process by specifying its file name and arguments is similar to typing the file name and command-line arguments in the Run dialog box of the Windows Start menu. 因此,檔案名不需要代表可執行檔。Therefore, the file name does not need to represent an executable file. 它可以是與系統上安裝之應用程式相關聯的任何檔案類型。It can be of any file type for which the extension has been associated with an application installed on the system. 例如,如果您有與編輯器相關聯的文字檔(例如 [記事本]),檔案名的副檔名可以是 .txt,或者如果您有相關聯的 .doc 檔案與文字處理工具(例如 Microsoft Word),它可能會有 .doc。For example the file name can have a .txt extension if you have associated text files with an editor, such as Notepad, or it can have a .doc if you have associated.doc files with a word processing tool, such as Microsoft Word. 同樣地,如同Run對話方塊可以接受包含或不含 .exe 副檔名的可執行檔名稱一樣,在fileName參數中,.exe 副檔名是選擇性的。Similarly, in the same way that the Run dialog box can accept an executable file name with or without the .exe extension, the .exe extension is optional in the fileName parameter. 例如,您可以將fileName參數設定為 "notepad.exe" 或 "notepad"。For example, you can set the fileName parameter to either "Notepad.exe" or "Notepad". 如果參數代表可執行檔,則arguments參數可能代表要採取行動的檔案,例如中Notepad.exe myfile.txt的文字檔。 fileNameIf the fileName parameter represents an executable file, the arguments parameter might represent a file to act upon, such as the text file in Notepad.exe myfile.txt. 如果參數代表命令(.cmd)檔案arguments ,參數必須包含 "/c" 或 "/k" 引數,以指定命令視窗是否會在完成後結束或保留。 fileNameIf the fileName parameter represents a command (.cmd) file, the arguments parameter must include either a "/c" or "/k" argument to specify whether the command window exits or remains after completion.

與其他多載不同的是, Start沒有參數的多載static不是成員。Unlike the other overloads, the overload of Start that has no parameters is not a static member. 當您已經建立實例、指定了Process開始資訊(包括檔案名),而且想要啟動進程資源,並將它與現有Process的實例產生關聯時,請使用該多載。Use that overload when you have already created a Process instance, specified start information (including the file name), and want to start a process resource and associate it with the existing Process instance. 當您想要static建立新Process的元件,而不是啟動現有元件的進程時,請使用其中一個多載。Use one of the static overloads when you want to create a new Process component rather than start a process for an existing component. 這個多載和沒有參數的多載,可讓您指定要啟動的進程資源的檔案名,以及要傳遞的命令列引數。Both this overload and the overload that has no parameters allow you to specify the file name of the process resource to start and command-line arguments to pass.

如果您在系統中使用引號宣告了 path 變數,則在啟動該位置中找到的任何進程時,必須完整限定該路徑。If you have a path variable declared in your system using quotes, you must fully qualify that path when starting any process found in that location. 否則,系統將找不到路徑。Otherwise, the system will not find the path. 例如,如果c:\mypath不在您的路徑中,而且您使用引號來加入它: path = %path%;"c:\mypath",則在啟動它時,您c:\mypath必須完整限定中的任何程式。For example, if c:\mypath is not in your path, and you add it using quotation marks: path = %path%;"c:\mypath", you must fully qualify any process in c:\mypath when starting it.

注意

ASP.NET 網頁和伺服器控制項程式碼會在 Web 服務器上的 ASP.NET worker 進程內容中執行。ASP.NET Web page and server control code executes in the context of the ASP.NET worker process on the Web server. 如果您使用 ASP.NET Start網頁或伺服器控制項中的方法,新的進程會在具有限制許可權的 Web 服務器上執行。If you use the Start method in an ASP.NET Web page or server control, the new process executes on the Web server with restricted permissions. 進程不會在與用戶端瀏覽器相同的內容中啟動,也無法存取使用者桌面。The process does not start in the same context as the client browser, and does not have access to the user desktop.

每當您使用Start來啟動處理常式時,可能需要關閉它或遺失系統資源的風險。Whenever you use Start to start a process, you might need to close it or you risk losing system resources. 使用CloseMainWindowKill關閉處理常式。Close processes using CloseMainWindow or Kill. 您可以使用其HasExited屬性來檢查進程是否已關閉。You can check whether a process has already been closed by using its HasExited property.

這裡有關于受控執行緒中的公寓狀態的注意事項。A note about apartment states in managed threads is necessary here. UseShellExecute位於StartInfo main()進程元件的屬性時,請確定您已透過在方法上設定屬性[STAThread] ,在應用程式上設定執行緒模型。 trueWhen UseShellExecute is true on the process component's StartInfo property, make sure you have set a threading model on your application by setting the attribute [STAThread] on the main() method. 否則, unknown managed 執行緒可以處於狀態或進入MTA狀態,後者會與UseShellExecute true發生衝突。Otherwise, a managed thread can be in an unknown state or put in the MTA state, the latter of which conflicts with UseShellExecute being true. 某些方法需要單元狀態不是unknownSome methods require that the apartment state not be unknown. 如果未明確設定狀態,當應用程式遇到這種方法時,它會預設為MTA,且一旦設定,就無法變更單元狀態。If the state is not explicitly set, when the application encounters such a method, it defaults to MTA, and once set, the apartment state cannot be changed. 不過, MTA當作業系統 shell 管理執行緒時,會導致擲回例外狀況。However, MTA causes an exception to be thrown when the operating system shell is managing the thread.
