Enterprise Library: Logging Block and Email

问题

Does anyone have a tutorial link or an example on how to use the Logging block to send out error email?

You need to set up an EmailTraceListener in the Logging Application Block.

You can use the Enterprise Library UI but the web.config section ends up looking something like this:

<loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="Default" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add toAddress="admin@company.com" fromAddress="fromemail@company.com"
        subjectLineStarter="" subjectLineEnder="" smtpServer="127.0.0.1"
        smtpPort="25" formatter="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        traceOutputOptions="None" filter="All" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        name="Email" />
    </listeners>
    <categorySources>
      <add switchValue="All" name="Default">
        <listeners>
          <add name="Email" />
        </listeners>
      </add>    
    </categorySources>
</loggingConfiguration>

This will work providing your SMTP server is set up correctly. You can use Telnet to check that by sending command line email.
