如何从使用另一控制器的一个控制器加载视图？

Question

Really simple question: I want to be able to redirect from one page to another in Razor MVC.

The user clicks a link on the first page, which calls a method on the first controller. This method uses data from its own model, as well as methods from the second controller, to construct a model for the second controller.

I now wish to display that second view using the newly constructed model. However, there doesn't seem to be a way to use View() to do this (unless I'm blind). The two controllers are in different folders, so it can't automatically find the page to load.

Any ideas?

您可以使用类似

return View("../FolderName/ViewName", model);

Answer 2

It sounds like this has answered this question here: How to simulate Server.Transfer in ASP.NET MVC?

In summary you should look at:

return RedirectToRoute(new { controller = "home"});

or look at some other redirection options:

• Redirect to action and need to pass data
• Redirect to different controller

Answer 3

Ideally you cannot return a view from Different Controller and Different Action. But you can return a view from same controller and different action.

To Answer your question, We can always redirect to Different controller and Different Actions. In this scenario it will be a 302 GET request .So if you cannot pass models across Controllers.

(Though you can pass as route values,which will be appended in querystring.(This is not at all advised))

Best approach will be either ,

1) Keep both the actions in same controller.

or

2) Create the model with in the Action of 2nd Controller.

Answer 4

If the page should redirect to the correct URL for the second controller, I would:

1. Send to the first controller.
2. Add model to TempData.
3. Return RedirectResult to second controller.
4. Retrieve first model from TempData.
5. Process and return consolidated model.

If you don't want a redirect, you might consider turning the actions from the first controller into an ActionFilter. That filter can be applied to both controller actions (first and second). Your initial view would post to the second controller directly and the ActionFilter would help create that part of your model.
