RedirectToAction and RedirectToRoute
提问by user1079925
In my controller of webpage 1, I want to redirect to Webpage 2, passing 2 variables.
在我的网页 1 控制器中，我想重定向到网页 2，传递 2 个变量。
I tried using RedirectToRoute, but cannot get it to work; wrong URL is displayed. I then switched to using RedirectToAction.
我尝试使用 RedirectToRoute，但无法让它工作；显示错误的网址。然后我切换到使用 RedirectToAction。
my code:
我的代码：
Routing
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 (which works)
RedirectToAction（有效）
return RedirectToAction("Index", "UsersAdditionalPreviousNames", new { userId = user.Id, applicantId = applicant.Id });
RedirectToRoute (doesn't work)
RedirectToRoute（不起作用）
return RedirectToRoute("CreateAdditionalPreviousNames", new { userId = user.Id, applicantId = applicant.Id });
Oh, and one other thing, can you make parameters required, rather than optional....if so, how?
哦，还有一件事，你能不能让参数成为必需的，而不是可选的……如果是这样，怎么做？

Omit parameter defaults to make parameters required:
省略参数默认值以使参数成为必需：
routes.MapRoute(
"CreateAdditionalPreviousNames", // Route name
"Users/{controller}/{action}/{userId}/{applicantId}", // URL with parameters
new { controller = "UsersAdditionalPreviousNames", action = "Index" }
);
For route redirect, try this:
对于路由重定向，试试这个：
return RedirectToRoute(new
{
controller = "UsersAdditionalPreviousNames",
action = "Index",
userId = user.Id,
applicantId = applicant.Id
});
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:
我从史蒂夫桑德森那里学到的另一个习惯是不命名你的路线。每个路由都可以有一个空名称，这使您可以明确指定所有参数：
routes.MapRoute(
null, // Route name
"Users/{controller}/{action}/{userId}/{applicantId}", // URL with parameters
new { controller = "UsersAdditionalPreviousNames", action = "Index" }
);
