Ejemplos

En el ejemplo de código siguiente se crea una carpeta SQL Server, se comprueba que existe y, a continuación, se quita la carpeta y se vuelve a comprobar su existencia. También guarda un paquete y comprueba que el paquete se guardó mediante el ExistsOnSqlServer método .

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);  
            app.SaveToSqlServerAs(pkg, null, "newPkg", "yourserver", null, null);  

            // Verify that the package was saved.  
            Boolean packageExists = app.ExistsOnSqlServer("newPkg", "yourserver", null, null);  
            Console.WriteLine("Package exists? {0}", packageExists);  

            //Remove the folder.  
            app.RemoveFolderFromSqlServer("myNewFolder", "yourserver", null, null);  

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

Sub Main(ByVal args() As String)  
            ' The variable pkg points to the location  
            ' of the ExecuteProcess package sample

            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)
