Trace.Listeners
Property
Definition
Gets the collection of listeners that is monitoring the trace output.
public static System.Diagnostics.TraceListenerCollection Listeners { get; }
Property Value
A TraceListenerCollection that represents a collection of type TraceListener monitoring the trace output.
Examples
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
/* Create a ConsoleTraceListener and add it to the trace listeners. */
ConsoleTraceListener myWriter = new
ConsoleTraceListener();
Trace.Listeners.Add(myWriter);
' Create a ConsoleTraceListener and add it to the trace listeners.
Dim myWriter As New ConsoleTraceListener()
Trace.Listeners.Add(myWriter)
Remarks
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.
