SQL テーブルをスキャンし、各レコード値からオブジェクトを作成し、それを他の SSIS フロー要素の隣に移動する必要がある SSIS を作成しています。

オブジェクト型変数 (MyObject) とスクリプト タスクを作成しました。私のスクリプト タスクでは、次のコードを書きました。

RequestObject reqObj = new RequestObject();
reqObj.building = Dts.Variables["reqObj_Building"].Value.ToString();
reqObj.ID = Convert.ToInt32(Dts.Variables["reqObj_DeviceID"].Value);
//...

reqObjに assinするために次のコードを書いてみましたmyObject。

Dts.Variables["myObject"].Value = new RequestObject();
Dts.Variables["myObject"].Value = reqObj;

しかし、これらの行は次の実行時例外をスローします:

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.
 ---> System.Runtime.InteropServices.COMException (0xC0010009): The element cannot be found in a collection. This error happens when you try to retrieve an element from a collection on a container during execution of the package and the element is not there.

カスタム オブジェクトを SSIS オブジェクト型変数に割り当てるにはどうすればよいですか? それは可能ですか？ありがとう
