Provides a multilevel switch to control tracing and debug output without recompiling your code.
Assembly: System (in System.dll)
You can set the event level of a through the application configuration file and then use the configured level in your application. Alternatively, you can create a in your code and set the level directly, to instrument a specific section of code.
To configure a , 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.
