I have a view which contains a form, the form posts and the data gets processed etc, then I want to return the view Index, so return view("Index");
我有一个视图，它包含一个表单，表单post和数据被处理等等，然后我想返回视图索引，所以返回视图(“Index”);
however this will then complain about my ViewData not existing, I get the feeling that the controller code under Index() isn't being processed which adds the list it requires to the ViewData, anyone know what's wrong?
然而，这将会抱怨我的ViewData不存在，我感觉在索引()下的控制器代码没有被处理，它添加了对ViewData所需要的列表，谁知道是哪里出了问题?
Thanks
谢谢
edit: Apparently it's done to prevent recursion.. in which case, I'm lost as to what to do without repeating all my ViewData stuff both Controllers
编辑:显然是为了防止递归。在这种情况下，我不知道该怎么做而不重复所有的ViewData内容两个控制器

I think you should have two actions: one that processes the form submission, and another one that collects data for the view. Once the form has been processed, you call return RedirectToAction("Index") and you are done. I hope I understood what you meant by this.
我认为您应该有两个动作:一个是处理表单提交，另一个是为视图收集数据。处理完表单后，调用return RedirectToAction(“Index”)，就完成了。我希望我理解你的意思。

If your Index method on the controller does a return View("Index"); then just call the Index method with any parameters it requires. Then the method will populate the ViewData reuired by the Index View.
如果控制器上的索引方法执行返回视图(“Index”);然后用它需要的任何参数调用索引方法。然后该方法将通过索引视图填充ViewData。
