例

次の例は、NetMsmqBinding バインドを使用するようにサービスを構成する方法を示しています。

まず、構成ファイルを示します。

次に、実際のサービス コードを示します。

    [OperationContract(IsOneWay = true)]
    void Subtract(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Multiply(double n1, double n2);
    [OperationContract(IsOneWay = true)]
    void Divide(double n1, double n2);
}

注釈

NetMsmqBinding バインドは、Microsoft Message Queuing (MSMQ) をトランスポートとして使用することによってキューのサポートを提供し、疎結合アプリケーション、失敗の切り分け、読み込みの均一化、および切断操作のサポートを有効にします。 これらの機能の詳細については、「 キューの概要」を参照してください。

これは、Windows Communication Foundation (WCF) によって提供されるシステム提供のバインディングの 1 つです。 手順としては、構成値を使用するバインディングを定義し、コードベースの方法を使用しないことをお勧めします。ただし、サービスの初期化時に構成値を設定する必要がある特定の高度なシナリオの場合は除きます。
