c# - Log4net 对待异常的方式不同于其他日志消息

Question

我想为异常设置这样的模式:

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="[%-5level] %date{HH:mm:ss}: %message%newlineException: %exception{message}%newlineStackTrace: %exception{stacktrace}%newline" />
  </layout>

虽然我想为非异常设置这样的模式:

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="[%-5level] %date{HH:mm:ss}: %message%newline" />
  </layout>

我怎样才能做到这一点？

这与日志级别无关，因为它可能是DEBUG、DEBUG-EXCEPTION，以及ERROR 或错误异常

不完全确定您在寻找什么，但我认为它已经可以做到这一点。只要您像这样记录异常:

try 
{
throw new Exception();
}
catch (Exception ex)
{
Log.Error("There was an exception!", ex)
}

这是 PowerGUI VSX 的示例:
