매개 변수

• pIDTSOutput
  The output of the upstream component.

• pIDTSInput
  The input of the downstream component.

주의

In addition to establishing the flow of data between an IDTSOutput90 and an IDTSInput90 input, this method also notifies each component of the event by calling the OnInputPathAttached and OnOutputPathAttached methods of the component.

예

The following code example demonstrates how to create a new path and establish the path between two components.

using System;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime;

...

    public static void main( string []args )
    {
        // Create the package and add a data flow task.
        Package p = new Package();
        TaskHost th = p.Executables.Add("DTS.Pipeline",null) as TaskHost;
        MainPipe m = th.InnerObject as MainPipe;

        // Create an OLE DB source component.
        IDTSComponentMetaData90 md = AddComponentToDataFlow( m , "DTSAdapter.OLEDBSource");
        IDTSComponentMetaData90 oledbSrc = m.ComponentMetaDataCollection.New();
        CManagedComponentWrapper90 srcWrp = oledbSrc.Instantiate();
        srcWrp.ProvideComponentProperties();

        // Create an OLE DB destination component.
        IDTSComponentMetaData90 oledbDest = AddComponentToDataFlow( m , "DTSAdapter.OLEDBDestination");
        IDTSComponentMetaData90 destWrp = oledbDest.ComponentMetaDataCollection.New();
        CManagedComponentWrapper90 destWrp = md.Instantiate();
        destWrp.ProvideComponentProperties();

        // Establish the path.
        IDTSPath90 path = m.PathCollection.New();
        path. AttachPathAndPropagateNotifications( oledbSrc.OutputCollection[0], oledbDest.InputCollection[0]);

}
public IDTSComponentMetaData90 AddComponentToDataFlow( MainPipe mp , string Component )
{
    if( mp != null )
    {
        IDTSComponentMetaData90 md = mp.ComponentMetaDataCollection.New();
        md.ComponentClassID = Component;
        CManagedComponentWrapper wrp = md.Instantiate();
        wrp.ProvideComponentProperties();

        return md;
    }
    throw new Exception( "DataFlow task does not exist.");
}

 path.AttachPathAndPropagateNotifications(oledbSrc.OutputCollection(0), oledbDest.InputCollection(0)) 
End Sub
