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
<form name="form1" action="/Home/Index" method="post">
Name:<input type="text" name="name" /><br />
Sex: <input type="text" name="sex" />
<input type="submit" value="submit" />
</form>
<%
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();
}
