	string message,
	string detailMessage
)

Parameters

message
Type: System.String

A message to emit.

detailMessage
Type: System.String

The default behavior is to display the message and detailed message in a message box when the application is running in a user-interface mode, and to the TraceListener instances in a TraceListenerCollection collection.
