The following code example creates a SQL Server folder, verifies that it exists, and then removes the folder and rechecks its existence. It also saves a package and verifies that the package was saved using the ExistsOnSqlServer method.

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 p 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() 
 
            ' Create a folder on SQL Server in the msdb database.
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", Nothing, Nothing)
 
            ' Verify that the folder exists by using ExistsOnSqlServer method.
            Dim folderExists As Boolean =  app.FolderExistsOnSqlServer("myNewFolder","yourserver",Nothing,Nothing) 
            Console.WriteLine("Folder exists? {0}", folderExists)
 
            ' Load a package and save it.
            Dim pkg As Package =  app.LoadPackage(p,Nothing) 
            app.SaveToSqlServerAs(pkg, Nothing, "newPkg", "yourserver", Nothing, Nothing)
 
            ' Verify that the package was saved.
            Dim packageExists As Boolean =  app.ExistsOnSqlServer("newPkg","yourserver",Nothing,Nothing) 
            Console.WriteLine("Package exists? {0}", packageExists)
 
            'Remove the folder.
            app.RemoveFolderFromSqlServer("myNewFolder", "yourserver", Nothing, Nothing)
 
            ' Verify that the folder was removed by using the ExistsOnSqlServer method.
            folderExists = app.FolderExistsOnSqlServer("myNewFolder", "yourserver", Nothing, Nothing)
            Console.WriteLine("Folder exists? {0}", folderExists)
End Sub

Sample Output:

Folder exists? True

Package exists? True

Folder exists? False
