更改MVC控制器中的URL导航 [英] Change the URL navigation in MVC controller

问题描述

当我在我的主页面完成我的工作时，我必须去巢1.

我尝试从下一页控制器那样做`loginController`

当我在主控制器中时，我使用以下功能：

While I Finishing my job in my main page I have to go to the nest one.
I try to do that from the next page controller lets say `loginController`
While I'm in the main controller I use the following function for this purpose:

Public Sub FlagBtn_Click(ByVal myFlag As String) As ActionResult
            Attributes.envProp._LanguageFlag = myFlag
            Attributes.mvcLogin.Index()
        End Sub

程序进入接下来`loginController`并在那里执行函数：

The program goes to the next `loginController` and executes the function there:

<Route("Login")>
       Function Index() As ActionResult
           Return View()
       End Function

通常需要更改` url`也可以根据`route file`

Which normally has to change the `url` as well according to the `route file`

routes.MapRoute(
          name:="Default",
          url:="{controller}/{action}/{id}",
          defaults:=New With {.controller = "main", .action = "Index", .id = UrlParameter.Optional}
      )

但这不会发生。而不是那个`url`导航仍然在`Default`路线上，当然下一页无法显示。

这里的问题是如何更改`url`导航，根据我选择去的页面。



我尝试了什么：



没有比我已经做过的更多

But that doesn't happen. Instead of that the `url` navigation remains on the `Default` route and of course the next page can't be display.
The question here is how to change the `url` navigation, according to page I choose to go.

What I have tried:

Nothing more than I have already done

推荐答案

使用 RedirectToAction [ ^ ]将浏览器重定向到另一个动作。

Use RedirectToAction[^] to redirect the browser to another action.

Public Sub FlagBtn_Click(ByVal myFlag As String) As ActionResult
    Attributes.envProp._LanguageFlag = myFlag
    Return RedirectToAction("Index", "login")
End Sub

注意：该方法的第一行看起来很可疑。您是否尝试在请求之间的字段中存储值？那不行。您需要使用会话状态或 TempData 集合来保存数据。

NB: The first line of that method looks suspicious. Are you trying to store values in a field between requests? That won't work. You'd need to use session state, or the TempData collection, to persist the data.
