PS：一个Home控制器里两个Action方法Index和Temp 分别对应两个视图；
Index页面用于显示单个参数传值
Temp页面用于显示多个参数参数
(项目命名空间：MVC多种传值方式)
两个类：
Student : public int stuId { get; set; } public string stuName { get; set; } public int stuAge { get; set; } public char stuSex { get; set; } public string stuEmail { get; set; }
User : public int uId { get; set; } public string uName { get; set; } public string uPwd { get; set; }
后台Index方法(后台传递单个参数的几种方法)：
public ActionResult Index()
{
#region ViewData传值
//1)、传递对象
ViewData["stu"] = new Student()
{
stuId = 1,
stuName = "麻花筒",
stuSex = '男',
stuAge = 20,
stuEmail = "25476342@qq.com"
};
//2)、传递标量值
ViewData["flag"] = "能服于忍";
#endregion
#region ViewBag传值
//1)、传递对象
ViewBag.stu2 = new Student()
{
stuId = 2,
stuName = "张三",
stuSex = '男',
stuAge = 18,
stuEmail = "1472583699@qq.com"
};
//2）、传递标量值
ViewBag.flag2 = "精忠报国";
#endregion
#region TempData传值
//1)、传递对象
TempData.Add("stu3", new Student()
{
stuId = 3,
stuName = "李四",
stuSex = '女',
stuAge = 20,
stuEmail = "1574258632@qq.com"
});
//2）、传递标量值
TempData["flag3"] = "白昼流星";
//3)、说明：使用Add方法和使用键值对作用是一样的;
#endregion
#region @model传值
return View(new Student()
{
stuId = 4,
stuName = "王五",
stuSex = '男',
stuAge = 16,
stuEmail = "145236987@qq.com"
});
#endregion
}

Index页面:

#endregion
#region Tuple传值(元数组)

var tuple = new Tuple<Student, Student, string, User, Tuple<Student, User>>(
