Remarks

The Switch property of the TraceSource class is a SourceSwitch object. The SourceSwitch class provides a Level property to test the event level of the switch. The Level property gets or sets the switch's TraceLevel value.

You can set the event level of a SourceSwitch through the application configuration file and then use the configured SourceSwitch level in your application. Alternatively, you can create a SourceSwitch in your code and set the level directly, to instrument a specific section of code.

To configure a SourceSwitch, edit the configuration file that corresponds to the name of your application. Within this file, you can set a switch's value or clear all the switches previously set by the application. The configuration file should be formatted as shown in the following example.

<switches>  
  <add name="SourceSwitch" value="Verbose"></add>  
</switches>  

The switch is used to check whether a trace should be propagated or ignored. Each TraceSource trace method calls the ShouldTrace method before calling the listeners. If the ShouldTrace method returns false, the trace is ignored and the trace method exits. If the ShouldTrace method returns true, the trace is passed to the listeners.

Constructors

SourceSwitch(String)	Initializes a new instance of the SourceSwitch class, specifying the name of the source.
SourceSwitch(String, String)	Initializes a new instance of the SourceSwitch class, specifying the display name and the default value for the source switch.
