I wrote a Log class derived from System.Diagnostics.TraceListener like so

public class Log : TraceListener

This acts as a wrapper to Log4Net and allows people to use System.Diagnostics Tracing like so

Trace.Listeners.Clear();
Trace.Listeners.Add(new Log("MyProgram"));
Trace.TraceInformation("Program Starting");

There is a request to add additional tracing levels then the default Trace ones (Error,Warning,Information)

I want to have this added to the System.Diagnostics.Trace so it can be used like

Trace.TraceVerbose("blah blah");
Trace.TraceAlert("Alert!");

Is there any way I can do this with an extension class? I tried

public static class TraceListenerExtensions
{
     public static void TraceVerbose(this Trace trace) {}
}

but nothing is being exposed on the trace instance being passed in :(
