推荐答案

他们有不同的背景。

OnActionExecuted 有一个<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.mvc.actionexecutedcontext%28v=vs.100%29.aspx\">ActionExecutedContext在其中您可以查看由动作产生的结果。您还可以查看操作是否遇到异常，看看异常被处理的。

OnActionExecuted has a ActionExecutedContext in which you can view the result produced by the action. You can also see whether the action encountered an Exception and see if the exception was handled.

OnResultExecuting 有一个<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.mvc.resultexecutingcontext%28v=vs.100%29.aspx\">ResultExecutingContext.这种方法被称为的ActionResult 实例调用之前。可以检查方法的结果和可能取消的结果的执行。这通常会导致与状态code 200的空白响应（你不能在OnActionExecuted方法做到这一点）。

OnResultExecuting has a ResultExecutingContext. This method gets called just before the ActionResult instance is invoked. You can examine the result of the method and possibly cancel the execution of the result. This will usually result in a blank response with status code 200. (you can't do this in the OnActionExecuted method).
