1. Request.Form读取表单数据

HomeController代码如下：

    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewData["Message"] = "Welcome to ASP.NET MVC!";

            return View();
        }

        public ActionResult About()
        {
            return View();
        }
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult RequestForm()
        {
            Person person=new Person();
            person.FirstName = Request.Form["FirstName"];
            person.LastName = Request.Form["LastName"];
            return View(person);
        }
    }
    public  class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

Index.aspx代码如下：

     <% using (Html.BeginForm("RequestForm", "Home")) { %>FirstName: <% =Html.TextBox("FirstName")%><br/>
         LastName: <% =Html.TextBox("LastName")%><br/>  <input type="submit"  name="submit" value="RequestForm" /><br/>
　　　<%} %>

右键Add View添加选择Details

2. FormCollection读取表单

HomeController代码如下：

   [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewData["Message"] = "Welcome to ASP.NET MVC!";

            return View();
        }

        public ActionResult About()
        {
            return View();
        }
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult FormCollection(FormCollection formCollection)
        {
            Person person=new Person();
            person.FirstName = formCollection["FirstName"];
            person.LastName = formCollection["LastName"];
            return View(person);
        }
    }
    public class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

Index.aspx代码如下：

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <h2>
        <%: ViewData["Message"] %></h2>
    <%using (Html.BeginForm("FormCollection", "Home"))
      {%>
    FirstName:<%:Html.TextBox("FirstName") %><br />
    LastName:<%:Html.TextBox("LastName") %><br />
    <input type="submit" name="submit" value="FormCollection" /><br />

        }
        [AcceptVerbs(HttpVerbs.Post)]

    }
    public class Person
