MVC使用Log4Net进行错误日志记录学习笔记4_实用技巧_

 using System.Web.Mvc; namespace PMS.WebApp.Models { public class Log4ExceptionAttribute:HandleErrorAttribute { /// 
 /// 重写OnException方法来捕获异常数据 /// 
 ///  public override void OnException(ExceptionContext filterContext) { base.OnException(filterContext); //捕获当前异常数据 var ex = filterContext.Exception; } } } 

 using System.Web.Mvc; using PMS.WebApp.Models; namespace PMS.WebApp { public class FilterConfig { public static void RegisterGlobalFilters(GlobalFilterCollection filters) { //filters.Add(new HandleErrorAttribute()); filters.Add(new Log4ExceptionAttribute()); } } } 

 using System; using System.Collections.Generic; using System.Web.Mvc; namespace PMS.WebApp.Models { public class Log4ExceptionAttribute:HandleErrorAttribute { public static Queue Exceptions=new Queue(); /// 
 /// 重写OnException方法来捕获异常数据 /// 
 ///  public override void OnException(ExceptionContext filterContext) { base.OnException(filterContext); //捕获当前异常数据 var ex = filterContext.Exception; //将异常数据入队 Exceptions.Enqueue(ex); //跳转到错误页面 filterContext.HttpContext.Response.Redirect("/Error.html"); } } }
