C# SMS API - onMessageDeliveryFailed
This event is invoked by the SMS Gateway if the SMS is not accepted by the network for delivery or the network returns a delivery report with negative statuscode meaning that the message could not be delivered.
To handle this event, the following delegate type is used:
public delegate void FailureEventHandler(string messageID, int errorCode, string errorMessage, DateTime errorTime);
And the following event is used:
public event FailureEventHandler onMessageDeliveryFailed;
Name | Description | |
![]() |
void onMessageDeliveryFailed( string messageID, int errorCode, string errorMessage, DateTime errorTime ); |
Create a function with this header and attach it to the onMessageDeliveryFailed event to receive notifications about message delivery failures. Parameters messageID - The message
id that was returned by the SMS Gateway when you have posted
the message for sending using the
sendMessage method. Example Step 1. - Create the event handling function:void myDeliveryFauilureHandler(string messageID,int errorCode, string errorMessage, DateTime errorTime) { console.writeln("The message delivery has failed because "+errorMessage); };Step 2. - Attach this event to the SMSClient object: mySMSClient.onMessageDeliveryFailed += ServerEventSink.wrap(myDeliveryFauilureHandle);Hint: Notice the ServerEventSink.wrap method, that is used to attach the event. This wrapper is used to work around an error that can happen when asynchronous callbacks are invoked in .NET remoting. |
