ViewBag、ViewData、TempData的使用和区别

 1 ViewBag.Message = "Your application description page.";
 2 ViewData["Message"] = "Your application description page.";
 3 List<string> colors = new List<string>();
 4 ViewBag.Listcolors = colors;
 5 ViewData["Listcolors"] = colors;
 6 //在View中访问
 7 @{
 8     List<string> clist = ViewBag.Listcolors as List<string>;
 9     List<string> clist = ViewData["Listcolors"] as List<string>;
10     //然后通过for/foreach进行使用
11 }
12 @ViewData["Message"]
13 @ViewBag.Message

1 Dictionary<string, string> address = new Dictionary<string, string>();
2 List<string> modules = new List<string>();
3 ViewBag.Address = address;
4 ViewBag.Modules = modules;
5 //在View中访问
6 @ViewBag.Address[键值1];@ViewBag.Address[键值2];@ViewBag.Address[键值3];//通过键值进行访问
7 @ViewBag.Modules[0];@ViewBag.Modules[1];@ViewBag.Modules[2];//通过索引进行访问

1 public ActionResult Index(){
2     TempData["abc"] = "this is tempdata";
3     return View();
4 }
5 //在About视图里面调用
6 @TempData["abc"];
