log4net 自定义日志级别记录多个日志

程序中原来只记录一个日志，现在我要写一个用户操作日志，需要与原来的日志分开，在config文件中一阵折腾无果(要么写不全，要么写重了，反正没办法完美分离，要么与现存代码没办法完美兼容)，差点放弃准备自己直接写txt文件了。

在网上看到可以写自定义filter，可以and可以or，那还有什么事情是搞不定的呢？代码比较简单，不解释。

public class AndFilter : 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

            }

            return FilterDecision.Accept;

        }

        public IFilter Filter

        {

            set { filters.Add(value); }

        }

        public bool AcceptOnMatch

        {

            get { return acceptOnMatch; }

            set { acceptOnMatch = value; }

        }

    }

    public class OrFilter : 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.Accept;

            }

            return FilterDecision.Deny;

        }

        public IFilter Filter

        {

            set { filters.Add(value); }

        }

        public bool AcceptOnMatch

        {

            get { return acceptOnMatch; }

            set { acceptOnMatch = value; }

        }

    }
