在MVC4中，如何使用Url中的参数从控制器动作重定向到视图？

Question

In my MVC4 login view, I have several sections defined:

• login - /User/Login#login or - /User/Login
• register - /User/Login#register
• lostpassword - - /User/Login#lostpassword

The JS on the page picks up the right form area to present.

Everything works fine for login - validation, etc. However if the registration fails, how do I return to the view with the added #register parameter?

-- Update -- I forgot to mention that this is from a controller and all validation errors need to be passed back to it. So, return Redirect("...") doesn't work

Answer 1

The following does the trick

return Redirect(Url.Action("Login", "User") + "#registerform");

URL is ~/Login/User#registerform .

Answer 2

This way will work:

return RedirectToAction("NewAction", new { 
     id = model.Id, 
     registerParam = model.registerId
});

PS: If New Action fails you can do the same thing back to the current action method, with some error parameter.
