LOG操作类

using

 System;

using  System.IO;

namespace  TankAction.SystemLog

{

    /**//// <summary>

    /// LogHelper的摘要说明。

    /// </summary>

    public class LogHelper

    {

        private SystemLog()

        {

        }

        public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");

        public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");

        public static void SetConfig()

        {

            log4net.Config.DOMConfigurator.Configure();

        }

        public static void SetConfig(FileInfo configFile)

        {

            log4net.Config.DOMConfigurator.Configure(configFile); 

        }

        public static void WriteLog(string info)

        {

            if(loginfo.IsInfoEnabled)

            {

                loginfo.Info(info);

            }

        }

        public static void WriteLog(string info,Exception se)

        {

            if(logerror.IsErrorEnabled)

            {

                logerror.Error(info,se);

            }

        }

    }

}

Global.asax.cs文件配置如下：

  

protected   void  Application_Start(Object sender, EventArgs e)

  

{

            SystemLog.SetConfig();

  }

  

protected   void  Application_Error(Object sender, EventArgs e)

  

{

   Exception objExp = HttpContext.Current.Server.GetLastError();

   LogHelper.WriteLog("/r/n客户机IP:"+ Request.UserHostAddress +"/r/n错误地址:"+ Request.Url +"/r/n异常信息:"+ Server.GetLastError().Message,objExp);

  }

eg:

   try

   {}

   catch(Exception ex)

   {

       LogHelper.WriteLog("ErrorInfo"ex);

   }
