Notas
This class represents the data flow task, and is used when programmatically building a data flow layout. An instance of the class is created by adding the data flow task to the Executables collection of a Package. Components are added to the task using the ComponentMetaDataCollection property. Connections are established between components using the PathCollection property.
Ejemplos
The following code example adds a data flow task to a package, adds an OLE DB source component and an OLE DB destination component, and establishes a path between the two components.
using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
namespace Microsoft.Samples.SqlServer.Dts
{
public class Class1
{
public static void Main(string []args)
{
// Create the package.
Package p = new Package();
// Add the data flow task.
MainPipe mp = ((TaskHost)p.Executables.Add("SSIS.Pipeline.2")).InnerObject as MainPipe;
// Add the OLE DB source component.
IDTSComponentMetaData100 mdOleDbSrc = mp.ComponentMetaDataCollection.New();
mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource";
mdOleDbSrc.Name = "OLEDB Source";
CManagedComponentWrapper wrpOledbSrc = mdOleDbSrc.Instantiate();
// Add the OLE DB destination component.
IDTSComponentMetaData100 mdOleDbDest = mp.ComponentMetaDataCollection.New();
mdOleDbDest.ComponentClassID = "DTSAdapter.OleDbDestination";
mdOleDbDest.Name = "OLEDB Destination";
CManagedComponentWrapper wrpOledbDest = mdOleDbSrc.Instantiate();
// Create a path and attach the output of the source to the input of the destination.
IDTSPath100 path = mp.PathCollection.New();
path.AttachPathAndPropagateNotifications(mdOleDbSrc.OutputCollection[0], mdOleDbDest.InputCollection[0]);
}
}
}
