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.
