Emits or displays a message for an assertion that always fails.
[Visual Basic] Overloads Overridable Public Sub Fail( _ ByVal message As String _ ) [C#] public virtual void Fail( string message ); [C++] public: virtual void Fail( String* message ); [JScript] public function Fail( message : String );
The default behavior is to output the message to a message box when the application is running in a user interface mode, and to the TraceListener instances in a TraceListeners collection. By default, the TraceListeners collection has an instance of a DefaultTraceListener. You can customize this behavior by adding a TraceListener to or removing one from the collection.
