Asp.Net MVC中捕捉错误路由并设置默认Not Found页面。

在Global中写一个Application_Error捕捉错误路由并重定向到Not Found页面。这里是全局性抓取错误路由，此处还可以写由错误路由导致访问失败的日志记录。

 1   protected void Application_Error(object sender, EventArgs e)
 2         {
 3             var httpContext = ((MvcApplication)sender).Context;
 4             var currentController = "";
 5             var currentAction = "";
 6             var currentRouterData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));
 7 
 8             if (currentRouterData != null)
 9             {
10                 if (currentRouterData.Values["controller"] != null && !string.IsNullOrEmpty(currentRouterData.Values["controller"].ToString()))
11                 {
12                     currentController = currentRouterData.Values["controller"].ToString();
13                 }
14 
15                 if (currentRouterData.Values["action"] != null && !string.IsNullOrEmpty(currentRouterData.Values["action"].ToString()))
16                 {
17                     currentAction = currentRouterData.Values["action"].ToString();
18                 }
19             }
20 
21             var ex = Server.GetLastError();
22             //record error log here.
23 
24             var controller = new ErrorController();
25             var routeData = new RouteData();
26             var action = "Index";
27 
28             if (ex is HttpException)
29             {
30                 var httpEx = ex as HttpException;
31 
32                 switch (httpEx.GetHttpCode())
33                 {
34                     case  404:
35                         action = "Not Found";
36                         Response.Redirect("/Error/index");
37                         break;
38                 }
39 
40                 httpContext.ClearError();
41                 httpContext.Response.Clear();
42                 httpContext.Response.StatusCode = ex is HttpException ? ((HttpException)ex).GetHttpCode() : 500;
43                 httpContext.Response.TrySkipIisCustomErrors = true;
44 
45                 routeData.Values["controller"] = "Error";
46                 routeData.Values["action"] = action;
47             }
48         }
