1. 添加Log4net引用
2. 添加配置文件
Log.config

Web.config
<!--log4net日志配置文件-->
<add key="log4net" value="config/log4net/log.config" />
3. 注册lognet
protected void Application_Start() { //注册lognet var log4NetFileName = FilePath(ConfigurationManager.AppSettings["log4net"]); if (File.Exists(log4NetFileName)) { XmlConfigurator.ConfigureAndWatch(new FileInfo(log4NetFileName)); } } private static string FilePath(string name) { if (string.IsNullOrEmpty(name)) { return string.Empty; } return string.Format("{0}/{1}", AppDomain.CurrentDomain.BaseDirectory.TrimEnd('\', '/'), name.TrimStart('\', '/')); }
4. 编写Helper
using log4net; using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace Log4NetTest { public static class Log4NetUtility { /// <summary> /// 写日志 /// </summary> public static void WriteLog(this string message, string name, Log4NetType logType = Log4NetType.Info) { var log = GetLog(name); if (log == null) { return; } if (logType == Log4NetType.Debug) { log.Debug(message); return; } if (logType == Log4NetType.Error) { log.Error(message); return; } if (logType == Log4NetType.Fatal) { log.Debug(message); return; } if (logType == Log4NetType.Info) { log.Info(message); return; } log.Warn(message); } /// <summary> /// 写异常日志 /// </summary> public static void WriteLog(this Exception exception, string name) { var log = GetLog(name); if (log == null) { return; } WriteLog(exception, log); } /// <summary> /// 写异常日志 /// </summary> private static void WriteLog(Exception exception, ILog log) { if (exception == null) { return; } log.Error(exception); WriteLog(exception.InnerException, log); } /// <summary> /// 获取日志对象 /// </summary> public static ILog GetLog(string name) { var logger = LogManager.GetLogger(name); return logger; } } /// <summary> /// Log4Net类型枚举 /// </summary> public enum Log4NetType { /// <summary> /// 字段Debug /// </summary> Debug, /// <summary> /// 字段Error /// </summary> Error, /// <summary> /// 字段Info /// </summary> Info, /// <summary> /// 字段Fatal /// </summary> Fatal, /// <summary> /// 字段Warn /// </summary> Warn } /// <summary> /// 类名称：Log4NetName /// 命名空间：DaiShu.Crm.Utility /// 类功能：日志名称 /// </summary> public class Log4NetName { /// <summary> /// 字段UrlFilter /// </summary> public const string Log4NetTest = "Log4NetTest"; /// <summary> /// 字段UrlFilter /// </summary> public const string UrlFilter = "RYJ.Crm.UrlFilter"; /// <summary> /// 字段System /// </summary> public const string System = "RYJ.Crm.System"; /// <summary> /// 字段Quartz /// </summary> public const string Quartz = "RYJ.Crm.Quartz"; /// <summary> /// 字段Service /// </summary> public const string Service = "RYJ.Crm.Services"; /// <summary> /// 字段ExternalService /// </summary> public const string ExternalService = "RYJ.Crm.ExternalService"; /// <summary> /// 字段Return /// </summary> public const string Return = "RYJ.Return"; /// <summary> /// 字段HeartBeat /// </summary> public const string HeartBeat = "RYJ.Crm.HeartBeat"; /// <summary> /// 字段Event /// </summary> public const string Event = "RYJ.Crm.Event"; } }
