ASP.NET MVC

Model:数据和业务规则 data and business rules

View: 结果展示 output and representation

Controller: 把用户输入转变成 Model能处理的数据

访问localhost/Home/index.aspx,

实际机制：HomeControl.cs中的 Action index;

返回机制：返回Views/Controller/index.aspx

总结：请求aspx时,是请求control类下的action方法

返回views时,是返回View目录下的Control类的action.aspx.

MVC官方入门例子

http://www.asp.net/mvc/tutorials/getting-started-with-aspnet-mvc3/cs/intro-to-aspnet-mvc-3

        // GET: /HelloWorld/
        #region  为Controller类添加Action方法
        /*MVC默认的Mapping format*/
        public string Index() //调用方式  Controller前缀/Index
        {
            return "this is <b>default</b> action";
        }
        //public string Welcome() //调用方式  Controller前缀/Welcome
        //{
        //    return "this is Welcome action";
        //}
        //http://localhost:7391/HelloWorld/Welcome?name=Scott&numtime=1  //调用时，url的参数名必须和形参同名
        public string Welcome(string name, int numtime) //在Control中不许出现函数重载,
        {
            return "Hello " + name + "numTime is:" + numtime.ToString();
        }
        #endregion

△ Controller解析URL和参数, 将结果写到ViewData（键值对）,ViewBag中，View再生成结果页面

public class HelloWorldController:Controller
{       
 public ActionResult Welcome(string name, int numtime)
        {
            ViewData["Message"] = "Hello " + name;
            ViewData["Numtime"] = numtime;
            return View();
        }
}

WelCome.aspx

    <h2>Welcome</h2>
    <ul>
       <%for (int i = 0; i <= Convert.ToInt32(ViewData["numtime"]); i++) {%>
            <li><%=ViewData["Message"].ToString()%></li>
       <%}%> 
    </ul>
