The following code example creates a new TraceSwitch and uses the switch to determine whether to emit error messages. The switch is created at the class level. MyMethod writes the first error message if the Level property is set to TraceLevel.Warning or higher. However, MyMethod does not write the second error message when the Level is less than TraceLevel.Verbose.
