Action context for MVC: ActionExecutingContext

Let's see, everyone, ActionExecutingContext object A total of 3 references. Below I come one by one parse:

Call base. OnActionExecuting (Filtercontext) After this, will not perform the subsequent actionfilter, if you are sure only one, or do not want to follow up, then you can not call the statement

FilterContext.ActionDescriptor.ActionName the action name executed by the context

Filtercontext.result is the custom result returned after executing the context action.

And then we'll take a look at this actionexecutingcontext class, see

Here's a clearer explanation of what the ActionExecutingContext class can do for you. Of course, I would like to say that this class is generally used to filter the custom filter, for the controller itself inherits the ActionFilterAttribute base class, so it can be rewritten onactionexecuting the following describes the class-related methods

Method	Parameters	Describe
OnActionExecuting	ActionExecutingContext	Execute before the behavior method executes
onactionexecuted	ActionExecutedContext	Executes after the behavior method executes
Onresultexecuting	ResultExecutingContext	Executes before the behavior method returns
onresultexecuted	ResultExecutedContext	Executes after the behavior method returns

The four method execution order is onactionexecuting-->onactionexecuted-->onresultexecuting-->onresultexecuted
