MVC的路径选择十分灵活，可以用类似/parm1/parm2/parm3/ 的方式(这个有点象iis的urlrewriter)，也可以象传统url那样用/?parm1=a&parm2=b&parm3=c这样访问

关键是Global.asax中Route规则的配置

以下是一个Global.asax的示例:

protected void Application_Start(object sender, EventArgs e)

        {

            // Note: Change Url= to Url="[controller].mvc/[action]/[id]" to enable 

            //       automatic support on IIS6



            RouteTable.Routes.Add(new Route

            {

                Url = "[controller]/[action]",

                Defaults = new { action = "Index" },

                RouteHandler = typeof(MvcRouteHandler)

            });

            RouteTable.Routes.Add(new Route

            {

                Url = "[controller]/[action]/[id]",

                Defaults = new { action = "Index", id = (int?)null },

                RouteHandler = typeof(MvcRouteHandler)

            });


            RouteTable.Routes.Add(new Route

            {

                Url = "[controller]/[action]/[id]/[name]",

                Defaults = new { action = "Index", name = (string)null,id=(int?)null },

                RouteHandler = typeof(MvcRouteHandler)

            });



            RouteTable.Routes.Add(new Route

            {

                Url = "[controller]/[action]/[id]/[name]/[sex]",

                Defaults = new { action = "Index", name = (string)null, id = (int?)null,sex=(string)null },

                RouteHandler = typeof(MvcRouteHandler)

            });   


            RouteTable.Routes.Add(new Route

            {

                Url = "Default.aspx",

                Defaults = new { controller = "Home", action = "Index", id = 2, name = "Jimmy",sex="female" },

                RouteHandler = typeof(MvcRouteHandler)

            });

        }

对应的HomeController文件:

public class HomeController : Controller

    {       

        /// <summary>

        /// Example URL: /Home/Index/?id=2&name=abc&sex=male (对应Url = "[controller]/[action]")                     

        ///              /Home/Index/2/?name=abc&sex=male  (对应Url = "[controller]/[action]/[id]")          

        ///              /Home/Index/2/abc/?sex=male  (对应Url = "[controller]/[action]/[id]/[name]")

        ///              /Home/Index/2/abc/male/ (对应Url = "[controller]/[action]/[id]/[name]/[sex]")

        ///              /Home/Index/2/abc/  (对应Url = "[controller]/[action]/[id]/[name]")

        ///              /Home/Index/2/ (对应Url = "[controller]/[action]/[id]")

        /// </summary>

        /// <param name="id"></param>

        [ControllerAction]

        public void Index(int? id,string name,string sex)

        {

            ViewData["id"] = id;

            ViewData["name"] = name;

            ViewData["sex"] = sex;

            RenderView("Index");

        }      

    }

对应的Index视图:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="MVCDemo.Views.Home.Index" %>



<asp:Content ID="Content2" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">



    <h2>Welcome to my ASP.NET MVC Application!</h2>

    

    id=<%=ViewData["id"] %> <br/>

    name=<%=ViewData["name"] as string %><br/>

    sex=<%=ViewData["sex"] as string %>



</asp:Content>
