範例

下列範例說明如何存取服務作業內訊息的 DeliveryStatus。

public void SimpleSubmitPurchaseOrder(PurchaseOrder po)
{
    Console.WriteLine("Submitting purchase order did not succeed ", po);
    MsmqMessageProperty mqProp = OperationContext.Current.IncomingMessageProperties[MsmqMessageProperty.Name] as MsmqMessageProperty;

    Console.WriteLine("Message Delivery Status: {0} ", mqProp.DeliveryStatus);
    Console.WriteLine("Message Delivery Failure: {0}", mqProp.DeliveryFailure);
    Console.WriteLine();
}

<OperationBehavior(TransactionScopeRequired := True, TransactionAutoComplete := True)> _
Public Sub SimpleSubmitPurchaseOrder(ByVal po As PurchaseOrder)
    Console.WriteLine("Submitting purchase order did not succeed ", po)
    Dim mqProp As MsmqMessageProperty = TryCast(OperationContext.Current.IncomingMessageProperties(MsmqMessageProperty.Name), MsmqMessageProperty)

    Console.WriteLine("Message Delivery Status: {0} ", mqProp.DeliveryStatus)
    Console.WriteLine("Message Delivery Failure: {0}", mqProp.DeliveryFailure)
    Console.WriteLine()
End Sub

備註

傳送給佇列的訊息可能會到達寄不出的信件佇列，這是因為該訊息未傳遞或是佇列管理員不確定傳遞結果。 當從寄不出的信件佇列讀取訊息時， DeliveryStatus 就是取得訊息傳遞狀態的一個方式。
