The following code example creates a folder on SQL Server, renames it, and then removes it. It also verifies the existence of the folder by using FolderExistsOnSqlServer.

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

Sample Output:

myNewFolderExists? True

myNewFolderExists has been renamed but still exists? False

myRenamedFolder now exists? True
