Question

我正在编写一个程序，我在其中使用NLog。我有几个课程，在所有课程中我都有属性

public string DeviceName { get; set; }

我希望记录器将它放在我的日志消息前面，所以如果我有两个类

class A 
{
    public DeviceName {get;set;} = "HMP20"
    public void methodOne() 
    {
        logger.Info("Something");
    }
}

class B 
{
    public DeviceName {get;set;} = "HMP30"
    public void methodOne() 
    {
        logger.Info("Something");
    }
}

然后日志文件中的输出应为

HMP20: Something
HMP30: Something

如何实现这一目标？

The fast solution is to use the logger-name as device-name:

  public class A
  {
    public string DeviceName {get => logger.Name; set => logger = NLog.LogManager.GetLogger(value); }
    private NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();
  }

  public class B
  {
    public string DeviceName {get => logger.Name; set => logger = NLog.LogManager.GetLogger(value); }
    private NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();
  }

Then you can use the following layout-renderer: ${logger:shortname=true}

NLog如何在日志中使用类成员变量？
