Please help: Log by Microsoft.Practices.EnterpriseLibrary.Logging 5.0 does not work?
===

I'm using Logging 5.0, when I call: 

LoggerUtils.WriteLog("test","test");

It passed but I have no log information.

Below is my configuration (at config.web):

        <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" />

      <errors switchValue="All" name="Logging Errors &amp; Warnings">
        <listeners>
          <add name="Event Log Listener" />
        </listeners>
      </errors>
    </specialSources>
  </loggingConfiguration>


I've configured the fileName="Log\test.log", but I have no data in it.

Please help me find out why the log does not work.

Thank you very much.
