TraceListener

Both Debug and Trace classes maintain a list of trace listeners.

The Debug and Trace inform the listeners in case of callings to Write, Fail and Trace methods.

There are predefined trace listeners:

The following code shows how to use the trace listener to record the debug message.


using System;
using System.Diagnostics;
class Program
{
    static void Main()
    {
        // Clear the default listener: 
        Trace.Listeners.Clear();
        Trace.Listeners.Add(new TextWriterTraceListener("trace.txt"));

        System.IO.TextWriter tw = Console.Out;
        Trace.Listeners.Add(new TextWriterTraceListener(tw));

        EventLog.CreateEventSource("DemoApp", "Application");
        Trace.Listeners.Add(new EventLogTraceListener("DemoApp"));
    }
}
