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);
}
