如何将ControllerContext传递给属性

Question

我想从Attribute \ Filter构造函数中使用来自ControllerContext或ActionContext的信息。我怎么能这样做？试图将ControllerContext作为参数传递给操作中的属性，但没有成功。

Answer 1

public override void OnActionExecuting(ActionExecutingContext filterContext) 
     { 
      var controllerContext = filterContext.Controller.ControllerContext; 

行动执行。您不能对建设

Answer 2

[HttpGet] 
    public ActionResult VideoStream(int id = 0) 
    { 
    } 
    public override void ExecuteResult(ControllerContext context) 
    { 
     string routedata = context.RequestContext.RouteData.Values["id"].ToString(); 
     //The File Path 
     var videoFilePath = HostingEnvironment.MapPath("~/CombineFile/Tanvir.mp4"); 
     //The header information 

    }
