建立一個空網站，添加Global.asax全域處理。

檔案目錄

 

在global類中添加代碼：

123456789101112131415161718192021222324252627282930313233

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Security;using System.Web.SessionState; namespace WebApplication{    public class Global : System.Web.HttpApplication    {         protected void Application_Start(object sender, EventArgs e)        {            Application["UserCount"] = 0;        }         protected void Session_Start(object sender, EventArgs e)        {            try            {                Application.Lock();                int countUser = (int)Application["UserCount"];                Application["UserCount"] = ++countUser;            }            catch            {            }            finally            {                Application.UnLock();            }        }

　　建立一個web表單applicationstateread類添加在如下代碼：

12345678910111213141516171819202122

public partial class ApplicationStateRead : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            int userCount = (int)Application["UserCount"];            Label1.Text = userCount.ToString();        }    }public partial class ApplicationStateRead : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            int userCount = (int)Application["UserCount"];            Label1.Text = userCount.ToString();        }    }public partial class ApplicationStateRead : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            int userCount = (int)Application["UserCount"];            Label1.Text = userCount.ToString();        }    }
