1.在AssemblyInfo中添加

[assembly: log4net.Config.XmlConfigurator()]

2.新建一个控制台应用程序，在项目中引用log4net.dll，然后修改app.config：

2.新建一个loggerhelper类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using log4net;
using System.Reflection;

namespace TestLog4Net
{
    public static class LoggerHelper
    {
        private static ILog log = log4net.LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

        /// 

        /// 获取当前 Ilog 对象
        /// 
        public static ILog GetILog
        {
            get
            {
                return log;
            }
        }
        /// 

        /// 记录错误日志
        /// 
        /// 
        /// 
        public static void Error(object message, Exception ex)
        {
            log.Error(message, ex);
        }
        /// 

        /// 记录严重错误
        /// 
        /// 
        /// 
        public static void Fatal(object message, Exception ex)
        {
            log.Fatal(message, ex);
        }
        /// 

        /// 记录一般信息
        /// 
        /// 
        public static void Info(object message)
        {
            log.Info(message);
        }
        /// 

        /// 记录调试信息
        /// 
        /// 
        public static void Debug(object message)
        {
            log.Debug(message);
        }
        /// 

        /// 记录警告信息
        /// 
        /// 
        public static void Warn(object message)
        {
            log.Warn(message);
        }
    }
}

3.使用loggerhelper类

using NLog;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace TestLog4Net
{
    class Program
    {
        static void Main(string[] args)
        {
            
            LoggerHelper.Error("这里存在错误",null);
            Console.ReadKey();
        }
    }
}
