我通过ViewBag从ActionFilter传递的数据无法在View中访问

您可以ViewBag在ViewResult其中设置要传递给视图的viewBag项目的属性 .您可以将动态对象设置为值.

filterContext.Result = new ViewResult
                          {
                             ViewName = "~/Views/Shared/Info.cshtml" ,
                             ViewBag= { Message="SS",Title="Hi title"}
                          };
