Debug.Write Method (Object, String)

Writes a category name and the value of the object's ToString method to the trace listeners in the Listeners collection.

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

[ConditionalAttribute("DEBUG")]
public static void Write(
	Object value,
	string category
)

Parameters

value
Type: System.Object

An object whose name is sent to the Listeners.

category
Type: System.String

A category name used to organize the output.

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

Use the category parameter to group output messages.

This method calls the Write 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 TraceLevel Error 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(Object myObject, String category) {
    // Write the message if the TraceSwitch level is set to Error or higher. 
    if(generalSwitch.TraceError)
       Debug.Write(myObject, category);

    // Write a second message if the TraceSwitch level is set to Verbose. 
    if(generalSwitch.TraceVerbose)
       Debug.WriteLine(" Object is not valid for this category.");
 }
