Ejemplos

En el ejemplo de código siguiente se crea una carpeta en SQL Server, se le cambia el nombre y, a continuación, se quita. También comprueba la existencia de la carpeta mediante 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);

            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);
