<assert> Element

Specifies whether to display a message box when you call the Debug.Assert method; also specifies the name of the file to write messages to.

<configuration>
   <system.diagnostics>
      <assert>

<assert assertuienabled="true|false" logfilename="file name"/>

Optional Attributes

Attribute	Description
assertuienabled	Specifies whether to display a message box when the Debug.Assert method evaluates to false. true Displays the message box. This is the default. false Does not display the message box.
logfilename	Specifies the name of the file to write the message to if Debug.Assert evaluates to false.

Remarks

      <assert assertuienabled="false" logfilename="c:\log.txt"/>
   </system.diagnostics>
</configuration>
