推荐答案

据我所知，这些是答案:

As far as i m understanding your question these are the answers :

第一个答案:

不可能有两个具有相同名称但结果也不同的控制器动作:

it's not possible to have two controller actions with the same name but with a different result also:

例如:

ActionResult YourAction() { ... } FileContentResult YourAction() { ... }

在MVC中，您也可以执行以下操作:

In MVC you can also do this :

[HttpGet] [ActionName("AnyAction")] ActionResult YourAction(firstModel model1) { ... } [HttpPost] [ActionName("AnyAction")] FileContentResult YourAction(secondModel model1) { ... }

这里的主要思想是，您可以使用ActionNameAttribute来命名具有相同名称的多个操作方法.

The main idea here is that you can use the ActionNameAttribute to name several action methods with the same name.
