定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回一个布尔值，该值指示指定的文件夹是否已存在于SQL Server实例上。

public:
 bool FolderExistsOnSqlServer(System::String ^ strFolderName, System::String ^ strServerName, System::String ^ strServerUserName, System::String ^ strServerPassword);

public bool FolderExistsOnSqlServer (string strFolderName, string strServerName, string strServerUserName, string strServerPassword);

member this.FolderExistsOnSqlServer : string * string * string * string -> bool

Public Function FolderExistsOnSqlServer (strFolderName As String, strServerName As String, strServerUserName As String, strServerPassword As String) As Boolean

参数

strFolderName

String

您所查找的文件夹：

strServerName

String

要搜索该包的 SQL Server 实例的名称。

strServerUserName

String

用于对 SQL Server 的实例进行身份验证的用户名。

strServerPassword

String

给定 strServerUserName 的密码。

返回

Boolean

如果文件夹存在于SQL Server的指定实例上，则为 true;如果文件夹不存在，则为 false。

示例

下面的代码示例在SQL Server上创建一个文件夹，将其重命名，然后将其删除。 It also verifies the existence of the folder by using FolderExistsOnSqlServer.

static void Main(string[] args)  
        {  
            // The variable pkg points to the location  
            // of the ExecuteProcess package sample   
            // that is installed with the SSIS samples.  
            string pkg = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            Application app = new Application();  
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", null, null);  

            // Verify that the folder was created.  
            Boolean ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", null, null);  
            Console.WriteLine("myNewFolderExists? " + ssFolder);  

            // Rename the myNewFolder to myRenamedFolder.   
            app.RenameFolderOnSqlServer("\\", "myNewFolder", "myRenamedFolder", "yourserver", null, null);  

            // Verify that the old folder does not exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", null, null);  
            Console.WriteLine("myNewFolderExists has been renamed but still exists? " + ssFolder);  

            // Verify that a folder with the new name does exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", null, null);  
            Console.WriteLine("myRenamedFolder now exists? " + ssFolder);  

            // Delete the folder.  
            app.RemoveFolderFromSqlServer("\\myRenamedFolder", "yourserver", null, null);  

            // Verify that the folder was removed.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", null, null);  
            Console.WriteLine("myRenamedFolder still exists? " + ssFolder);  
        }  

Sub Main(ByVal args() As String)  
            ' The variable pkg points to the location  
            ' of the ExecuteProcess package sample   
            ' that is installed with the SSIS samples.  
            Dim pkg As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx"   

            Dim app As Application =  New Application()   
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder was created.  
            Dim ssFolder As Boolean =  app.FolderExistsOnSqlServer("\\myNewFolder","yourserver",Nothing,Nothing)   
            Console.WriteLine("myNewFolderExists? " + ssFolder)  

            ' Rename the myNewFolder to myRenamedFolder.   
            app.RenameFolderOnSqlServer("\\", "myNewFolder", "myRenamedFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the old folder does not exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myNewFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myNewFolderExists has been renamed but still exists? " + ssFolder)  

            ' Verify that a folder with the new name does exist.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myRenamedFolder now exists? " + ssFolder)  

            ' Delete the folder.  
            app.RemoveFolderFromSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  

            ' Verify that the folder was removed.  
            ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", Nothing, Nothing)  
            Console.WriteLine("myRenamedFolder still exists? " + ssFolder)  
End Sub  

示例输出：

myNewFolderExists? True

myNewFolderExists has been renamed but still exists? False

myRenamedFolder now exists? True

myRenamedFolder still exists? False
