Parent Elements

Element

Description

configuration

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

listeners

Specifies a listener that collects, stores, and routes messages. Listeners direct the tracing output to an appropriate target.

system.diagnostics

Specifies trace listeners that collect, store, and route messages and the level where a trace switch is set.

trace

Remarks

Note

Removing the DefaultTraceListener from the Listeners collection alters the behavior of the Debug.Assert, Trace.Assert, Debug.Fail, and Trace.Fail methods. Calling an Assert or Fail method normally results in the display of a message box, however the message box is not displayed if the DefaultTraceListener is not in the Listeners collection.

Example

The following example shows how to remove the default trace listener from the trace Listeners collection.

<configuration>
   <system.diagnostics>
      <trace autoflush="true" indentsize="0">
         <listeners>
            <remove name="Default" />
         </listeners>
      </trace>
   </system.diagnostics>
</configuration>
