新建一个网站，然后在Default.aspx里添加代码如下：
<%@ Import Namespace="System.Web.SessionState" %>
<%@ Import Namespace="System.IO" %>
在相应位置添加代码如下：
void Application_Start(object sender, EventArgs e)
{
StreamReader rd = new StreamReader(Server.MapPath("counter.txt"));
int nNum = int.Parse(rd.ReadLine());
Application.Lock();
Application["Counter"] = nNum;
Application.UnLock();
rd.Close();
}
void Session_Start(object sender, EventArgs e)
{
Application.Lock();
Application["Counter"] = Convert.ToInt32(Application["Counter"]) + 1;
Application.UnLock();
//写入
StreamWriter sw = new StreamWriter(Server.MapPath("counter.txt"), false);//false为不追加
sw.WriteLine(Application["Counter"]);
sw.Close();
}
void Session_End(object sender, EventArgs e)
{
//写入
StreamWriter sw = new StreamWriter(Server.MapPath("counter.txt"),false);//false为不追加
sw.WriteLine(Application["Counter"]);
sw.Close();
}
最后你还要在程序目录里新建Counter.txt文件，就OK了
1<script language="c#" runat="server">
2 private void Page_Load(object sender, System.EventArgs e)
3 {
4 if (!IsPostBack)
5 GlobalGraph(MyPanel);
6 }
7 void GlobalGraph(Panel Container)
8 {
9 Label lbl;
10 Label lbl2;
11 string count;
12 lbl = new Label();
13 lbl2 = new Label();
14 lbl.Text = "该站点已被访问次数：";
15 Container.Controls.Add(lbl);
16 count = Application["Counter"].ToString();
17 for (int i = 0; i < count.Length; i++)
18
{
19 lbl2.Text=count.Substring(i, 1);
20
21 Container.Controls.Add(lbl2 ); //加载到控件容器
22
}
23 }
24 </script>
25
26<body style="background-color:White">
27<p><strong style=" font-family:@楷体_GB2312">Welcome to you!</strong> </p>
28 <form id="form1" runat="server">

31 </div>
32 </form>
33</body>
添加新项Global.asax文件，先声名，添加代码如下：<script language="c#" runat="server">2
private void Page_Load(object sender, System.EventArgs e)3
{
4
if (!IsPostBack)5
GlobalGraph(MyPanel);6
}7
void GlobalGraph(Panel Container)8

Label lbl2;11
string count;12
lbl = new Label();13
lbl2 = new Label();14
lbl.Text = "该站点已被访问次数：";15
Container.Controls.Add(lbl);16
count = Application["Counter"].ToString();17
for (int i = 0; i < count.Length; i++)18
{
19
lbl2.Text=count.Substring(i, 1); 20

Container.Controls.Add(lbl2 ); //加载到控件容器22
