Example

[Visual Basic, C#, JScript] The following example creates a TraceSwitch named generalSwitch. This switch is set outside of the code sample.

[Visual Basic, C#, JScript] 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.

[Visual Basic, C#, JScript] 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.

[Visual Basic, C#, JScript] Note   This example shows how to use one of the overloaded versions of Write. For other examples that might be available, see the individual overload topics.

[Visual Basic] 
' Class-level declaration.
' Create a TraceSwitch.
Private Shared generalSwitch As New TraceSwitch("General", "Entire Application")


Public Shared Sub MyErrorMethod(myObject As Object, category As String)
    ' Write the message if the TraceSwitch level is set to Error or higher.
    If generalSwitch.TraceError Then
        Debug.Write(myObject, category)
    End If 
    ' Write a second message if the TraceSwitch level is set to Verbose.
    If generalSwitch.TraceVerbose Then
        Debug.WriteLine(" Object is not valid for this category.")
    End If
End Sub 'MyErrorMethod 

[C#] 
// 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.");
 }


[JScript] 
// Class level declaration.
 // Create a TraceSwitch.
 static var generalSwitch : TraceSwitch = new TraceSwitch("General", "Entire Application");
 
 static public function MyErrorMethod(myObject : Object, category : String) {
    // 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.");
 }
