Beispiele

Im folgenden Codebeispiel wird ein SQL Server Ordner erstellt, überprüft, ob er vorhanden ist, und entfernt dann den Ordner und überprüft das Vorhandensein erneut. Außerdem wird ein Paket gespeichert und überprüft, ob das Paket mithilfe der ExistsOnSqlServer Methode gespeichert wurde.

static void Main(string[] args)  
        {  
            // The variable pkg points to the location  
            // of the ExecuteProcess package sample   
            // that is installed with the SSIS samples.

            Application app = new Application();

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

            // Verify that the folder exists by using ExistsOnSqlServer method.
