パラメーター

説明

このメソッドは、IDTSOutput100 出力と IDTSInput100 入力の間のデータのフローの確立に加え、コンポーネントの OnInputPathAttached メソッドと OnOutputPathAttached メソッドを呼び出すことによって、各コンポーネントに対してイベントの通知も行います。

使用例

次のコード例では、新しいパスを作成し、2 つのコンポーネント間にパスを確立しています。

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

...

    public static void main( string []args )

        MainPipe m = th.InnerObject as MainPipe;

        // Create an OLE DB source component.
        IDTSComponentMetaData100 md = AddComponentToDataFlow( m , "DTSAdapter.OLEDBSource");
