You can get the DeliveryFailure property to determine why a message failed delivery and was sent to the dead-letter queue. For additional information about message processing in a dead-letter queue, see Using Dead-Letter Queues to Handle Message Transfer Failures.

The example below shows how to access the DeliveryFailure 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();
}
