Examples

The following code example demonstrates the use of the UseAuthentication property.

// Set the queue's MessageReadPropertyFilter property 
// to enable the message's UseAuthentication property.
queue->MessageReadPropertyFilter->
    UseAuthentication = true;

// Peek at the message. Time out after ten seconds 
// in case the message was not delivered.
orderMessage = queue->Peek(TimeSpan::FromSeconds(10.0));

// Display the value of the message's 
// UseAuthentication property.
Console::WriteLine("Message.UseAuthentication: {0}", 
    orderMessage->UseAuthentication);

// Set the queue's MessageReadPropertyFilter property to enable the
// message's UseAuthentication property.
queue.MessageReadPropertyFilter.UseAuthentication = true;

// Peek at the message. Time out after ten seconds in case the message
// was not delivered.
orderMessage = queue.Peek(TimeSpan.FromSeconds(10.0));

// Display the value of the message's UseAuthentication property.
Console.WriteLine("Message.UseAuthentication: {0}",
    orderMessage.UseAuthentication);

Remarks

The UseAuthentication property of the Message class specifies whether the message needs to be authenticated.

It is not possible to look at the properties of a message and determine whether a message failed authentication. Messages that fail authentication are discarded and are not delivered to the queue.
