mvc笔记-HandleError用法

方式一：使用web.config配置

 [HandleError]
public class MvcHandleController : Controller
    {
       
        public ActionResult Index()
        {
            return View();
        }
    }

web.config配置如下

<customErrors mode="On" defaultRedirect="~/Account/Error">
      <error statusCode="403" redirect="~/404.html"/>
      <error statusCode="404" redirect="~/500.html"/>
 </customErrors>

方式二：

Controller

    public class MvcHandleController : Controller
    {
        [HandleError(View = "Error")]
        public ActionResult Index()
        {
            return View();
        }
    }

view

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<HandleErrorInfo>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    AboutError
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    通过强类型获取异常信息
    <%= Model.Exception.Message %>
</asp:Content>
