Writing to a new log file each day with TraceSource

I am using a logger in my application to write to files. The source, switch and listeners have been defined in the app.config file as follows:

  <system.diagnostics>
    <sources>
      <source name="LoggerApp" switchName="sourceSwitch" switchType="System.Diagnostics.SourceSwitch">
        <listeners>
          <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="myListener.log" />
        </listeners>
      </source>
    </sources>
    <switches>
      <add name="sourceSwitch" value="Information" />
    </switches>
  </system.diagnostics>

Inside, my .cs code, I use the logger as follows:

private static TraceSource logger = new TraceSource("LoggerApp");
logger.TraceEvent(TraceEventType.Information, 1, "{0} : Started the application", DateTime.Now);

What would I have to do to create a new log file each day instead of writing to the same log file every time?

Try use:

<system.diagnostics>
    <sources>
      <source name="LoggerApp" switchName="sourceSwitch" switchType="System.Diagnostics.SourceSwitch">
        <listeners>
          <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="myListener-{0:dd}-{0:MM}-{0:yyyy}.log" />
        </listeners>
      </source>
    </sources>
    <switches>
      <add name="sourceSwitch" value="Information" />
    </switches>
  </system.diagnostics>

You'd have to make your own TraceListener instead of using TextWriterTraceListener. This would allow your TraceListener implementation to change log files daily, or do any other custom behavior you wish.
