在MVC中，要把前端View中的值传递给后端Controller, 主要有两种方法

1. 利用Request.Form 或者 Request.QueryString

public ActionResult Index()    {        ViewData["Message"] = "Welcome to ASP.NET MVC!";        ViewData["name"] = Request.Form["name"];        ViewData["sex"] = Request.Form["sex"];        return View();    }

 

2. 利用FormCollection来获取页面上的值

public ActionResult Index(FormCollection form)    {        ViewData["Message"] = "Welcome to ASP.NET MVC!";        User u=new User();        u.Name = form["Name"];        u.Password = form["Password"];        return View(u);    }

 3）利用Action参数

     
              Name:
      
      
        Sex: 
              
          
     
    <%        if (ViewData["name"] != null)        {            Response.Write("your name is:" + ViewData["name"] + ",  your sex is:" + ViewData["sex"]);        }               %>    :    public ActionResult Index(string name, string sex)    {        ViewData["Message"] = "Welcome to ASP.NET MVC!";        ViewData["name"] = name;        ViewData["sex"] = sex;        return View();    }
