從MVC 4.0 ActionFilterAttribute我如何獲得當前的ApiController

Question

我想從filterContext獲取當前ApiController。它公開了一個控制器屬性，但ApiController實現了一些httpcontroller接口，不在那裏。

public override void OnActionExecuting(ActionExecutingContext filterContext) 

Answer 1

您會將其轉換回您的ApiController。像這樣：

var apiController = filterContext.Controller as ApiController; 
if (apiController != null) 
{ 
    //Do something with apiController. 
}
