Trace::Listeners Property

Gets the collection of listeners that is monitoring the trace output.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public:
static property TraceListenerCollection^ Listeners {
	TraceListenerCollection^ get ();
}

Property Value

Type: System.Diagnostics::TraceListenerCollection
A TraceListenerCollection that represents a collection of type TraceListener monitoring the trace output.

The listeners produce formatted output from the trace output. By default, the collection contains an instance of the DefaultTraceListener class. If you want to remove the default listener, call the Remove method, and pass it the instance of the DefaultTraceListener. To redirect output to the console window, add an instance of the ConsoleTraceListener class.

NoteNote

The Listeners collection is shared by both the Debug and the Trace classes; adding a trace listener to either class adds the listener to both.

The following example creates a ConsoleTraceListener that outputs to the console screen. The code then adds the new listener to the Listeners.


// Create a ConsoletTraceListener and add it to the trace listeners.
#if defined(TRACE)
ConsoleTraceListener^ myWriter = gcnew ConsoleTraceListener( );
Trace::Listeners->Add( myWriter );
#endif
