範例

下列範例示範如何使用WindowsIdentity類別的成員。The following example shows the use of members of WindowsIdentity class. 如需示範如何透過呼叫非受控 Win32 LogonUser函式來取得 Windows 帳戶權杖,以及使用該 token 來模擬另一位使用者的範例, WindowsImpersonationContext請參閱類別。For an example showing how to obtain a Windows account token through a call to the unmanaged Win32 LogonUser function, and use that token to impersonate another user, see the WindowsImpersonationContext class.

備註

呼叫方法,以建立代表WindowsIdentity目前使用者的物件。 GetCurrentCall the GetCurrent method to create a WindowsIdentity object that represents the current user.

重要

此型別代表 IDisposable 介面。This type implements the IDisposable interface. 當您完成使用型別時,您應該直接或間接處置它。When you have finished using the type, you should dispose of it either directly or indirectly. 若要直接處置型別,請呼叫其 try/catch 區塊中的 Dispose 方法。To dispose of the type directly, call its Dispose method in a try/catch block. 若要間接處置它,請使用語言建構函式,例如 using (在 C# 中) 或 Using (在 Visual Basic 中)。To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). 如需詳細資訊,請參閱 IDisposable 介面文章中的<使用實作 IDisposable 的物件>一節。For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

方法

Clone()

建立目前執行個體複本的新物件。Creates a new object that is a copy of the current instance.

Dispose()

GetCurrent(Boolean)

傳回表示執行緒或處理程序之 Windows 識別的 WindowsIdentity 物件,視 ifImpersonating 參數的值而定。Returns a WindowsIdentity object that represents the Windows identity for either the thread or the process, depending on the value of the ifImpersonating parameter.

GetCurrent(TokenAccessLevels)

GetHashCode()

做為預設雜湊函式。Serves as the default hash function.

(繼承來源 Object)
GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)

(繼承來源 Object)
RunImpersonated(SafeAccessTokenHandle, Action)

以模擬的 Windows 身分識別執行指定的動作。Runs the specified action as the impersonated Windows identity. 您可以使用 RunImpersonated(SafeAccessTokenHandle, Action) 並提供您的函式做為參數,而不需要使用個人化的方法呼叫並在 WindowsImpersonationContext 中執行您的函式。Instead of using an impersonated method call and running your function in WindowsImpersonationContext, you can use RunImpersonated(SafeAccessTokenHandle, Action) and provide your function directly as a parameter.

RunImpersonated<T>(SafeAccessTokenHandle, Func<T>)

以模擬的 Windows 身分識別執行指定的函式。Runs the specified function as the impersonated Windows identity. 您可以使用 RunImpersonated(SafeAccessTokenHandle, Action) 並提供您的函式做為參數,而不需要使用個人化的方法呼叫並在 WindowsImpersonationContext 中執行您的函式。Instead of using an impersonated method call and running your function in WindowsImpersonationContext, you can use RunImpersonated(SafeAccessTokenHandle, Action) and provide your function directly as a parameter.

ToString()
