They have a different context. 

<code>OnActionExecuted</code> has a <a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.actionexecutedcontext%28v=vs.100%29.aspx">ActionExecutedContext</a> 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.

<code>OnResultExecuting</code> has a <a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.resultexecutingcontext%28v=vs.100%29.aspx">ResultExecutingContext</a>. This method gets called just before the <code>ActionResult</code> 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).

They get called after one another. 

There can be no initialisation, since the ActionResult you are executing may not be rendering a View - ActionResults are free to do whatever they choose: return JSON, return a File, issue a redirect, etc.

They are called at different stages of the request as below
<ul>
<li>OnActionExecuting(ActionExecutingContext filterContext): Just before the action method is called.</li>
<li>OnActionExecuted(ActionExecutedContext filterContext): After the action method is called and before the result is executed (before view render).</li>
<li>OnResultExecuting(ResultExecutingContext filterContext): Just before the result is executed (before view render)</li>
<li>OnResultExecuted(ResultExecutedContext filterContext): After the result is executed (after the view is rendered).</li>

What is the difference between OnActionExecuted and OnResultExecuting? Do they both get fired right after each other once the action has been processed or does something happen in between these two methods. Like the initialisation of the View Engine, ...

OnActionExecuted和OnResultExecuting有什么区别？这两种方法都是在动作被处理后立即被解雇，还是在这两种方法之间发生了一些事情。就像视图引擎的初始化一样.
