How can i limit logging in my app using the web.config ?

Question

Hi ,

In my app I have logging , but I would like to limit what I log. So foir example if I have a setting in web.config to log the rrrors or information.

In my web.config file I have the following:

<system.diagnostics>
<trace autoflush="true"/>
<sources>
<source name="MyLogFileSource" switchValue="Error">
<listeners>
<remove name="Default"/>
<add name="MyLogFileListener"
      type="System.Diagnostics.TextWriterTraceListener"
     initializeData="iMyLogFileOrder.log"
     traceOutputOptions="DateTime">
</add>
</listeners>
</source>

I call a number of statements in my applications 

So for example 

try{

     ... some code 

     TraceSource LogFile = new TraceSource("MyLogFileSource", SourceLevels.All);

     LogFile.TraceInformation("TEST TO LOG ONLY ERRORS THIS SHOULD NOT BE LOGGED");

   .. some more code runs and exception happens here. So it falls through to the catch .

}

Catch Exception (ex) {

     LogFile.TraceEvent(TraceEventType.Error, 0, "Error MyLogFileSource: ");

     LogFile.TraceData(TraceEventType.Error, 0, ErrorMessage(ex));

}

Since the web.config is configured to error , I would have thought only the error would be logged and not the Information ,

"TEST TO LOG ONLY ERRORS THIS SHOULD NOT BE LOGGED"

Is the Web config configured correctly for the trace type ?

Would it log an exception regardless of the setting ?

Thanks
