Debug.WriteLine Method (String)
Assembly: System (in system.dll)
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 of 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. A line terminator follows the second message.
// Class-level declaration. // Create a TraceSwitch. static TraceSwitch generalSwitch = new TraceSwitch("General", "Entire Application"); static public void MyErrorMethod() { // Write the message if the TraceSwitch level is set to Error or higher. if(generalSwitch.TraceError) Debug.Write("My error message. "); // Write a second message if the TraceSwitch level is set to Verbose. if(generalSwitch.TraceVerbose) Debug.WriteLine("My second error message."); }
// Class-level declaration.
// Create a TraceSwitch.
private static TraceSwitch generalSwitch =
new TraceSwitch("General", "Entire Application");
public static void MyErrorMethod()
{
// Write the message if the TraceSwitch level is set to Error
// or higher.
if (generalSwitch.get_TraceError()) {
Debug.Write("My error message. ");
}
// Write a second message if the TraceSwitch level is set to Verbose.
if (generalSwitch.get_TraceVerbose()) {
Debug.WriteLine("My second error message.");
}
} //MyErrorMethod
// Class level declaration. // Create a TraceSwitch. static var generalSwitch : TraceSwitch = new TraceSwitch("General", "Entire Application"); static public function MyErrorMethod() { // Write the message if the TraceSwitch level is set to Error or higher. if(generalSwitch.TraceError) Debug.Write("My error message. "); //Write a second message if the TraceSwitch level is set to Verbose. if(generalSwitch.TraceVerbose) Debug.WriteLine("My second error message."); }
