注释

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.

示例

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("DTS.Pipeline")).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]);
        }
    }
}

Imports System 
Imports Microsoft.SqlServer.Dts.Runtime 
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper 
Namespace Microsoft.Samples.SqlServer.Dts 

 Public Class Class1 

   Public Shared Sub Main(ByVal args As String()) 
     Dim p As Package = New Package 
     Dim mp As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe) 
     Dim mdOleDbSrc As IDTSComponentMetaData100 = mp.ComponentMetaDataCollection.New 
     mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource" 
     mdOleDbSrc.Name = "OLEDB Source" 
     Dim wrpOledbSrc As CManagedComponentWrapper = mdOleDbSrc.Instantiate 
     Dim mdOleDbDest As IDTSComponentMetaData100 = mp.ComponentMetaDataCollection.New 
     mdOleDbDest.ComponentClassID = "DTSAdapter.OleDbDestination" 
     mdOleDbDest.Name = "OLEDB Destination" 
     Dim wrpOledbDest As CManagedComponentWrapper = mdOleDbSrc.Instantiate 
     Dim path As IDTSPath100 = mp.PathCollection.New 
     path.AttachPathAndPropagateNotifications(mdOleDbSrc.OutputCollection(0), mdOleDbDest.InputCollection(0)) 
   End Sub 
 End Class 
End Namespace
