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 }
