Question

我在MVC 4中有一个简单的控制器，就像这样。对不起，我是.net的大三学生，也许这很简单？

public class HomeController : BaseController
    {

        public ActionResult Index()
        {
            ViewBag.h1 = Resources.Language.HomeH1;
            ViewBag.Title = Resources.Language.HomeTitle;
            ViewBag.Description = Resources.Language.HomeDescription;
            return View();
        }

        public ActionResult Dataroom()
        {
            ViewBag.h1 = Resources.Language.DataRoomH1;
            ViewBag.Title = Resources.Language.DataroomTitle;
            ViewBag.Description = Resources.Language.DataroomDescription;
            return View();
        }

        public ActionResult Consultancy()
        {

            ViewBag.h1 = Resources.Language.ConsultancyH1;
            ViewBag.Title = Resources.Language.ConsultancyTitle;
            ViewBag.Description = Resources.Language.ConsultancyDescription;
            return View();
        }


        public ActionResult Services()
        {
            ViewBag.h1 = Resources.Language.ServicesH1;
            ViewBag.Title = Resources.Language.ServicesTitle;
            ViewBag.Description = Resources.Language.ServicesDescription;
            return View();
        }

        public ActionResult Contact()
        {

            ViewBag.h1 = Resources.Language.ContactH1;
            ViewBag.Title = Resources.Language.ContactTitle;
            ViewBag.Description = Resources.Language.ContactDescription;
            return View();
        }

当链接正常时它正在工作oK，但是如果someoen进入like / simpleexample等。我希望用户始终重定向到主页，这是一个简单的修复方法吗？

Answer 1

使用http状态代码404的自定义错误页面，并始终重定向到您的控制器操作。 ASP.NET MVC 404 Error Handling

Answer 2

在web.config中添加自定义错误页面网址

<customErrors mode="On" defaultRedirect="~/Home/Index" />

Answer 3

将此添加到配置：

<customErrors mode="On">
   <error statusCode="404" redirect="~/Home/Index"/>
</customErrors>

或其他方式：使用attrubute处理错误。创建属性：

public class HandleMyError : HandleErrorAttribute
    {
        public override void OnException( ExceptionContext filterContext )
        {
            if ( filterContext.ExceptionHandled ) { return ; }
            else
            {
                string actionName = filterContext.RouteData.Values["action"].ToString();
                Type controllerType = filterContext.Controller.GetType();
                var method = controllerType.GetMethod( actionName );
                var returnType = method.ReturnType;

                if ( returnType.Equals( typeof( ActionResult ) ) || ( returnType ).IsSubclassOf( typeof( ActionResult ) ) )
                {
                    filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { { "area", "" }, { "controller", "Home" }, { "action", "Index" } });
                }
            }

            filterContext.ExceptionHandled = true;
        }
    }

并为您的[HandleMyError]控制器添加Home属性：

[HandleMyError]
public class HomeController : BaseController
{
}

将用户重定向到主页C＃？
