Debug.WriteLine Method (String, String)

 

Writes a category name and message to the trace listeners in the Listeners collection.

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

[<ConditionalAttribute("DEBUG")>]
static member WriteLine : 
        message:string *
        category:string -> unit

Parameters

message
Type: System.String

A message to write.

category
Type: System.String

A category name used to organize the output.

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

The category parameter can be used to group output messages.

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 and the category on the same line as the first message. A line terminator follows the second message.
