ViewBag与ViewData有什么区别？ [英] What is the difference between ViewBag to ViewData ?

问题描述

ViewBag.LogoFileId = new SelectList(db.Files, "FileId", "FileId", chain.LogoFileId);
ViewBag.LangId = langId;
ViewData["catid"] = catid;
ViewData["languages"] = db.Languages.OrderBy(l => l.LanguageId).ToList();

推荐答案

ViewData就像一个你添加东西的集合，而ViewBag是一个动态类型，所以你只需设置和读取它的属性。 ViewData是在实现动态类型之前构思的，因此它是一种保存可在运行时定义的对象集合的方式。

ViewData acts like a collection you add things to, whereas ViewBag is a dynamic type so you simply set and read properties on it. ViewData was conceived before dynamic types were implemented so it was a way of holding a collection of objects you could define at run-time.
