新建一个网站，然后在Default.aspx里添加代码如下：

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

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

}
23

}
24

</script>
25

<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">
29

<div>
30

<asp:Panel id="MyPanel" runat="server" width="50%" BorderColor="#C0FFC0" BorderStyle="Groove"></asp:Panel>
31

</div>
32

</form>
33

</body>

添加新项Global.asax文件，先声名，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
