Trace.WriteLine Method (String)


Writes a message to the trace listeners in the Listeners collection.

Namespace:   System.Diagnostics
Assembly:  System (in System.dll)

static member WriteLine : 
        message:string -> unit


Type: System.String

A message to write.

By default, the output is written to an instance of DefaultTraceListener.

This method calls the WriteLine method of the trace listener.

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.

No code example is currently available or this language may not be supported.
