注释
The MainPipe (displayed as the Data Flow Task in Business Intelligence Development Studio) is the managed implementation of the IDTSPipeline100 COM interface. It is the interface used from managed code when programmatically creating or modifying a data flow task in a Package. For an overview of the methods and properties available to this object, see the MainPipeClass documentation.
示例
The following code example adds the MainPipe object to a Package and retrieves the MainPipe using the InnerObject property of the TaskHost.
Package p = new Package();
Executable e = p.Executables.Add("DTS.Pipeline.1");
TaskHost thMainPipe = e as TaskHost;
MainPipe dataFlowTask = thMainPipe.InnerObject as MainPipe;
