ASP.NET MVC：回报重定向和ViewData的 [英] ASP.NET MVC: return Redirect and ViewData

问题描述

我在我的母版登录框。只要登录信息是不正确的，我稳定物价计算机[loginError] 来显示错误信息给用户。

I have a login box in my MasterPage. Whenever the login information is not correct, I valorize ViewData["loginError"] to show the error message to the user.

登录是由于UserController的动作，使包含登录表单具有行动=/用户/登录。

Login is an action of the UserController, so the form that contains the login has action = "/User/Login".

作为一个用户可以尝试从任何页面登录，在成功的情况下，我重定向他到自己的个人网页，但在错误的情况下，我希望他留下来，他试图登陆非常同一页上。我发现，这个作品：

As a user can try to log in from any page, in case of success I redirect him to his personal page, but in case of error I want him to stay on the very same page where he tried to login. I've found that this works:

return Redirect(Request.UrlReferrer.ToString());

但似乎，因为我不返回正确的视图中，ViewData的数据丢失，所以我不能显示错误消息。

but it seems that, as I'm not returning a proper view, the data on ViewData is lost, so I cannot show the error message.

如何解决这一点，类似的问题任何建议？

Any suggestion on how to solve this and similar problems?

感谢

推荐答案

您可能需要使用的TempData 属性，这将在下一HTTP请求被持久化。

You probably want to use the TempData property, this will be persisted across to the next HTTP request.
