Esempio

L'esempio di codice seguente crea una cartella SQL Server, verifica che esista e quindi rimuove la cartella e ricontrolla l'esistenza. Salva anche un pacchetto e verifica che il pacchetto sia stato salvato usando il ExistsOnSqlServer metodo .

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 p = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            Application app = new Application();  

            // Create a folder on SQL Server in the msdb database.  
            app.CreateFolderOnSqlServer("\\", "myNewFolder", "yourserver", null, null);  

            // Verify that the folder exists by using ExistsOnSqlServer method.  
            Boolean folderExists = app.FolderExistsOnSqlServer("myNewFolder", "yourserver", null, null);  
            Console.WriteLine("Folder exists? {0}", folderExists);  

            // Load a package and save it.  
            Package pkg = app.LoadPackage(p, null);
