ViewBag&&ViewData(转载) - zLulus/My_Note GitHub Wiki

作用都是在View和Controller之间传值，是全局变量 ViewBag是dynamic，ViewData是字典 ViewBag比ViewData慢 ViewBag在ViewPage中查询数据时不需要类型转换，ViewData在ViewPage中查询数据时需要转换合适的类型

ViewData

<h1>@ViewData["Title"]</h1>

ViewData["Title"] = " UsingViewData";

ViewBag

<h1>@ViewBag.Title</h1>

ViewBag.Title = " Using ViewBag";
