示例
以下代码示例为包添加了一个数据流任务，添加了一个 OLE DB 源组件和一个 OLE DB 目标组件，并建立了两个组件之间的路径。
using System;
using Microsoft.SqlServer.Dts.Runtime.;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper.Sql2014;
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]);
}
}
}

注解
该类代表数据流任务，用于程序化构建数据流布局。 通过将数据流任务添加到ExecutablesPackage集合中创建该类的实例。 组件是通过该 ComponentMetaDataCollection 属性添加到任务中的。 通过该 PathCollection 属性建立组件之间的连接。
