jquery ajax/post/get 传参数给 mvc的action 1.ActionResult Test1 2.View Test1.aspx 3.ajax page 4.MetaObjectMigration.cs string json convert to class 5.相关的代码下载（包含用的相关类， jquery.json.js等）
ActionResult Test1
public ActionResult Test1(string nameJS, UserInfoInputData model, string js) { UserInfoInputData userinfo = new UserInfoInputData(); if (!string.IsNullOrEmpty(js)) { userinfo = (UserInfoInputData)js.ToInputDataObject(typeof(UserInfoInputData)); } ViewData["Time"] = model.Name + " :" + userinfo.Name; ViewData["Time2"] = model.age; ViewData["Message"] = "Test1 :" + nameJS + " :" + typeof(UserInfoInputData).ToString(); ViewData["js"] = userinfo.ToJSON(); return View(); }

ajax page 四种写法
