Trace.WriteLine Method (String)
Writes a message to the trace listeners in the Listeners collection.
Assembly: System (in System.dll)
The following example creates a TraceSwitch named generalSwitch. This switch is set outside the code sample.
If the switch is set to the TraceLevelError or higher, the example outputs the first error message to the Listeners. For information on adding a listener to the Listeners collection, see the TraceListenerCollection class.
Then, if the TraceLevel is set to Verbose, the example outputs the second error message on the same line as the first message. The second message is followed by a line terminator.
