创建一个basic类型的Project.

A.控制器相关文件:

HomeControlle.cs:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcSessionTest.Controllers{    public class HomeController : Controller    {        // GET: /Home/        public ActionResult Index()        {            return View();        }       [NonAction]       public   int  Add(int b)       {            int a = int.Parse(Session["a"].ToString());             return a + b;       }       public ActionResult Who()       {            Session["Name"] = "我是张三";            Session["a"] = 1;                       int a ;            a=Add(2);            return RedirectToAction("Show", "Other", new { i = a });             }       public ActionResult Abandon()       {            Session.Abandon();            return View("Index");       }           }}

OtherController.cs:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcSessionTest.Controllers{    public class OtherController : Controller    {        //        // GET: /Other/        public ActionResult Index()        {            return View();        }        public ActionResult Show(int i)        {            ViewBag.i =i.ToString();            return View();        }    }}

B.Views/Home下文件:Index.cshtml:

@{    ViewBag.Title = "Index";}<h2>Index</h2>@{       if(Session["Tip"]!=null&&Session["Tip"].ToString()!="")    {        <p>@Session["Tip"].ToString()</p>    }       if (Session["Name"] != null && Session["Name"].ToString() != "")       {        <p>@Session["Name"].ToString()</p>       }  }  @Html.ActionLink("Who?", "Who")  @Html.ActionLink("Abandon","Abandon","Home")

Views/Other下的文件:Show.cshtml:

@{    ViewBag.Title = "Show";}<h2>Show</h2><hr />@ViewBag.i <hr />@Session.SessionID<hr />@Session["Tip"].ToString()<hr />@Session["Name"].ToString()<hr />@Html.ActionLink("Index", "Index", "Home")

C.Global.asax.cs文件中添加:

  protected void Session_Start(object sender, EventArgs e)        {            Random r= new Random();            int i = r.Next(1000);            Session["Tip"] = "有一个人登录,随机数:"+i.ToString()+"  SessionID:"+Session.SessionID;        }        protected void Session_End(object sender, EventArgs e)        {         }
