CustomAppendar中LoggingEvent中的LocationInformation

Question

我已经写好了Appendar并覆盖了Append方法。我在该方法中获取LoggingEvent，但是当我查看LocationInformation时它是空的，它只显示“？”在以下属性中。

protected override void Append(log4net.Core.LoggingEvent loggingEvent)
{

ClassName = loggingEvent.LocationInformation.ClassName /*contains "?"*/,
MethodName = loggingEvent.LocationInformation.MethodName /*contains "?"*/,
FileName = loggingEvent.LocationInformation.FileName /*contains "?"*/,
FullInfo = loggingEvent.LocationInformation.FullInfo /*contains "?"*/,

}

我做错了什么？

由于

Answer 1

您可以尝试在自定义appender的构造函数中添加以下行：

Fix = FixFlags.All;

Answer 2

在Append-Method中设置LoggingEvent的Fix属性：

protected override void Append(LoggingEvent loggingEvent)
{
     loggingEvent.Fix = FixFlags.All;

     var className = loggingEvent.LocationInformation.ClassName;
     // ... 
}
