log4net.Filter.PropertyFilter无法正常工作

我是处理log4net过滤器的logenteries的新手我已尝试过剩余过滤器,例如"等级范围,stringtomatchLoggerMatchFilter"一切正常,但属性过滤器不起作用。我尝试了不同的解决方案,但它也没有用。

这是我的代码:

public class CustomFilter : FilterSkeleton
{
    private bool acceptOnMatch;
    private readonly IList<IFilter> filters = new List<IFilter>();

    public override FilterDecision Decide(LoggingEvent loggingEvent)
    {
        if (loggingEvent == null)
            throw new ArgumentNullException("loggingEvent");

        foreach (IFilter filter in filters)
        {
            if (filter.Decide(loggingEvent) != FilterDecision.Accept)
                return FilterDecision.Neutral; // one of the filter has failed
        }

        // All conditions are true
        if (acceptOnMatch)
            return FilterDecision.Accept;
        else
            return FilterDecision.Deny;
    }

    public IFilter Filter
    {
        set { filters.Add(value); }
    }

    public bool AcceptOnMatch
    {
        get { return acceptOnMatch; }
        set { acceptOnMatch = value; }
    }

}

我在log4net filter - how to write AND filter to ignore log messages中看到了这个解决方案,但对我来说,过滤器没有添加到接口。我是否无法直接添加过滤器?在 loggingevent 我传递消息属性中的数据,但我不知道如何添加到属性中,任何人都可以引导我,我不要&# 39;不知道如何调用此函数。

Webconfig:

   <filter type="Namespace.CustomFilter, Assembly">
    <filter type="log4net.Filter.PropertyFilter">
      <key value="firstname" />
      <stringToMatch value="1234" />
    </filter>
    <filter type="log4net.Filter.PropertyFilter">
      <key value="address" />
      <stringToMatch value="abcdf" />
    </filter>
    <acceptOnMatch value="false" />
  </filter>

我错过了一些请帮助我的地方。我过去几个小时都在挣扎。

更新:

    public string logFilter()
     {
        log4net.Config.XmlConfigurator.Configure();

        ILog Log = LogManager.GetLogger(
            System.Reflection.MethodBase.GetCurrentMethod().DeclaringType
           );

        var ReferenceID = Guid.NewGuid().ToString();

        var firstname = "1234";
        var address ="abcdf";
        var sno = "12";

        Log.InfoFormat("firstname {0}-{1}", firstname, ReferenceID);

        Log.InfoFormat("address {0}-{1}", address, ReferenceID);

        Log.InfoFormat("sno {0}-{1}", sno, ReferenceID);

        return ReferenceID;
    }

这里决定()功能除了 filterskelton ,但属性过滤器没有应用它能够从 webconfig 读取详细信息,但它可以&# 39; t过滤日志消息是否有任何我错过的内容。

提前致谢!

如果其中一个过滤器返回FilterDecision.Neutral,则会记录日志消息。因此,您需要检查该消息是否同时通过所有过滤器

            public override FilterDecision Decide(LoggingEvent loggingEvent)
            {
                if (loggingEvent == null)
                    throw new ArgumentNullException("loggingEvent");

                if (filters.All(x => x.Decide(loggingEvent) != FilterDecision.Accept))
                {
                    return FilterDecision.Neutral;
                }

                // All conditions are true
                if (acceptOnMatch)
                    return FilterDecision.Accept;
                else
                    return FilterDecision.Deny;
            }

<强>更新: 我的log4net配置看起来像这样:

 <filter type="MyApp.CustomFilter, MyApp">
            <filter type="log4net.Filter.PropertyFilter">
              <key value="firstname" />
              <stringToMatch value="1234" />
            </filter>
            <filter type="log4net.Filter.PropertyFilter">
              <key value="address" />
              <stringToMatch value="abcdf" />
            </filter>
            <acceptOnMatch value="false"/>
          </filter>
        </appender>

示例如何检查记录

    Task.Run(() =>
    {
        log4net.ThreadContext.Properties["firstname"] = "123";
        Log.Info("123");
    });

    Task.Run(() =>
    {
        log4net.ThreadContext.Properties["firstname"] = "1234";
        Log.Info("1234");
    });

    Task.Run(() =>
    {
        log4net.ThreadContext.Properties["address"] = "abcdf";
        Log.Info("abcdf");
    });
