Examples

The following example shows how to access the DeliveryStatus of a message within a service operation.

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

Remarks

A message sent to a queue can land in a dead-letter queue because the message was not delivered or the Queue Manager is not sure of the delivery outcome. The DeliveryStatus is a way to get the status of message delivery when the message is read from a dead-letter queue.
