Child Elements

Parent Elements

Element	Description
configuration	The root element in every configuration file used by the common language runtime and .NET Framework applications.

Remarks

You can change the level of a trace switch by putting it in a configuration file. If the switch is a BooleanSwitch, you can turn it on and off. If the switch is a TraceSwitch, you can assign different levels to it to specify the types of trace or debug messages the application outputs.

Example

The following example shows how to use the <switch> element to set the General trace switch to the TraceLevel.Error level, and enable the Data Boolean trace switch.

<configuration>
   <system.diagnostics>
      <switches>
         <add name="General" value="4" />
         <add name="Data" value="1" />
      </switches>
   </system.diagnostics>
</configuration>
