在我的网页1的控制器，我要重定向到网页2，传递两个变量。

In my controller of webpage 1, I want to redirect to Webpage 2, passing 2 variables.

我试着用RedirectToRoute，但不能让它开始工作;显示错误的URL。 然后我切换到使用RedirectToAction。

I tried using RedirectToRoute, but cannot get it to work; wrong URL is displayed. I then switched to using RedirectToAction.

我的code：

路由

routes.MapRoute(
    "CreateAdditionalPreviousNames", // Route name
    "Users/{controller}/{action}/{userId}/{applicantId}", // URL with parameters
    new { controller = "UsersAdditionalPreviousNames", action = "Index", userId = UrlParameter.Optional, applicantId = UrlParameter.Optional } // Parameter defaults
);

RedirectToAction（其中工程）

RedirectToAction (which works)

return RedirectToAction("Index", "UsersAdditionalPreviousNames", new { userId = user.Id, applicantId = applicant.Id });

RedirectToRoute（不工作）

RedirectToRoute (doesn't work)

return RedirectToRoute("CreateAdditionalPreviousNames", new { userId = user.Id, applicantId = applicant.Id });

哦，还有一件事，你可以要求，而不是可选参数....如果是这样，如何​​？

Oh, and one other thing, can you make parameters required, rather than optional....if so, how?

推荐答案

省略参数默认为使参数要求：

Omit parameter defaults to make parameters required:

    routes.MapRoute(
    "CreateAdditionalPreviousNames", // Route name
    "Users/{controller}/{action}/{userId}/{applicantId}", // URL with parameters
    new { controller = "UsersAdditionalPreviousNames", action = "Index" }
);

有关路由重定向，试试这个：

For route redirect, try this:

return RedirectToRoute(new 
{ 
    controller = "UsersAdditionalPreviousNames", 
    action = "Index", 
    userId = user.Id, 
    applicantId = applicant.Id 
});

另一种习惯，我拿起从史蒂夫·桑德森没有命名您的路线。每个路由可以有一个空的名字，它让你显式地指定的所有参数：

Another habit I picked up from Steve Sanderson is not naming your routes. Each route can have a null name, which makes you specify all parameters explicitly:

    routes.MapRoute(
    null, // Route name
    "Users/{controller}/{action}/{userId}/{applicantId}", // URL with parameters
    new { controller = "UsersAdditionalPreviousNames", action = "Index" }
);
