ASP.NET MVC AsyncController xxx已完成
实现 ASP.NET MVC AsyncController 时，xxxCompleted 方法必须是 Public。我想知道这是否意味着可以直接调用 xxxCompleted 方法，或者是否使用 NonAction 或类似的方法在内部对其进行保护？
谢谢。
When implementing ASP.NET MVC AsyncController the xxxCompleted method has to be Public. I'm wondering if this means the xxxCompleted method can be invoked directly, or if this is protected internally using NonAction or something similar?
Thanks.

在内部（并且简单地），构造了异步控制器上的操作的
MethodInfo数组。构造时，Async和Completed后缀将从操作方法名称中删除。如果您尝试调用诸如
IndexCompleted之类的操作方法，则会搜索此数组，但由于数组中没有IndexCompleted（因为后缀已被删除），因此 < code>AsyncControllerActionInvoker 报告未找到任何操作。值得自己研究一下源代码：
Internally (and simplistically), there's an array of
MethodInfoof the actions on the async controller constructed. When it's constructed theAsyncandCompletedsuffixes are stripped off the action method names.If you try an call an action method such as
IndexCompletedthis array is searched but because there isn't anIndexCompletedin the array (because the suffixes have been removed) theAsyncControllerActionInvokerreports that no action was found.It's worth having a poke around the source code to see for yourself:
