Примеры
В следующем примере кода создается папка на SQL Server, она переименовывается и удаляется. Он также проверяет наличие папки с помощью 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);
// Verify that a folder with the new name does exist.
ssFolder = app.FolderExistsOnSqlServer("\\myRenamedFolder", "yourserver", null, null);
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);
Console.WriteLine("myRenamedFolder still exists? " + ssFolder);
