using System.Diagnostics;

Stream str = File.Create(@"c:\test_env\log.txt");
TextWriterTraceListener twl = new TextWriterTraceListener(str);
ConsoleTraceListener cwl = new ConsoleTraceListener();

EventSourceCreationData esct = new EventSourceCreationData("", ""); ;
esct.MachineName = ".";
esct.LogName = "Application";
esct.Source = "MyLog";
if (!EventLog.SourceExists("MyLog"))
{
EventLog.CreateEventSource(esct);
}

EventLogTraceListener elt = new EventLogTraceListener("MyLog");

Trace.Listeners.Add(twl);
Trace.Listeners.Add(cwl);
Trace.Listeners.Add(elt);
Debug.WriteLine("Hello Debug");
Trace.WriteLine("Hello Trace");
Trace.Flush();
