Debug.Listeners Property

Updated: September 2008

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

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

public static TraceListenerCollection Listeners { get; }

Property Value

Type: System.Diagnostics.TraceListenerCollection
A TraceListenerCollection representing a collection of type TraceListener that monitors the debug output.

The listeners produce formatted output from the debug output. By default, the collection contains an instance of the DefaultTraceListener class. 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. To redirect output to a file or stream, add an instance of the TextWriterTraceListener.

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 TextWriterTraceListener that outputs to the console screen. The code then adds the new listener to the Listeners.

/* Create a listener that outputs to the console screen, and 
  * add it to the debug listeners. */
 TextWriterTraceListener myWriter = new 
    TextWriterTraceListener(System.Console.Out);
 Debug.Listeners.Add(myWriter);
