EventLog appender C#不会在事件日志查看器中写入

Question

我需要让我的C#应用​​程序在Windows事件查看器中写入日志.

我用了 ,

 <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
  <param name="ApplicationName" value="DataLoader" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value='{"Processed":"%d{yyyy-MM-dd HH:mm:ss}","Loglevel":"%p","Service":"DataLoader","Instance":"","AdditionalInfo":"%c{1}|%M","logtext":"%m%n"}'/>
  </layout>
</appender>

控制台中没有错误,但它不会在Windows事件查看器中写入日志
