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。
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
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]);
}
}
}
注解
该类代表数据流任务，用于程序化构建数据流布局。 该类的实例是通过将数据流任务添加到包的可执行文件集合中创建的。 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。
