trace Listeners

Question

It looks like there are two methods for setting up trace listeners, Method 1 is:

 

Declare an instance of TraceSource class

Name the TraceSource

Call the respective methods.

Example:

 

TextWriterTraceListener txtTracer = new TextWriterTraceListener(@"c:\newtxtlistener.txt");

TraceSource DemoTrace = new TraceSource("DemoApp");

DemoTrace.Listeners.Add(txtTracer);

DemoTrace.Switch = new SourceSwitch("DemoApp.Switch", "Information");

DemoTrace.TraceInformation("Before writing to Console");

Console.WriteLine("Writing to the Console");

DemoTrace.TraceInformation("After writing to Console");

 

Or use Listener Objects

 

Example:

 

Trace.Listeners.Clear();

Trace.AutoFlush = true;

Trace.Listeners.Add(new TextWriterTraceListener(@"c:\newtxtlistener.txt"));

Trace.WriteLine("This is a test");

 

 

Does anyone know when to use one or the other, or is it just preference?

 

Thanks
