D. trace.writeline:
the debug and trace classes have a Listeners collection that holds references to listener objects. to direct output to locations. add a trace listener object to the listeners collection. EventlogTraceListener: sends output to an event log.
The following example creates a trace listener that sends output to an event log. First, the code creates a new EventLogTraceListener that uses the source myEventLogSource. Next, myTraceListener is added to the Trace.Listeners collection. Finally, the example sends a line of output to the Listeners object.
public static void Main(string[] args) {
// Create a trace listener for the event log.
EventLogTraceListener myTraceListener = new EventLogTraceListener(“myEventLogSource”);
// Add the event log trace listener to the collection.
Trace.Listeners.Add(myTraceListener);
// Write output to the event log.
Trace.WriteLine(“Test output”);
