在ASP.NET 实现页面点击数记录
方法1：
l 建立Default.aspx Web窗体
l 在Default.aspx.cs文件中加入如下代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace HitCount
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
Session["first"] = null;
}
int count = 0;
Application.Lock();
Application.Add("count", count);
if (Session.IsNewSession == true)
{
Application["count"] = (int)Application["count"] + 1;
}
Application.UnLock();
Response.Write("The page has been visited: " + Application["count"] + "Times!");
}
}
}
方法2：
l 建立counter.ascx 用户自定义控件，在根目录下加入counter.xml,如下
<?xml version="1.0" standalone="yes"?>
<counter>
<count>
<hits>0</hits>
</count>
</counter>
l Counter.ascx.cs文件中加入如下代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
namespace HitCount
{
public partial class counter : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
/*
使用Session目的是避免同一用户不同刷新页面使hits增加1
*/
Session["first"] = DateTime.Now;
this.HitCount();
}
DataSet tmpDS = new DataSet();
tmpDS.ReadXml(HttpContext.Current.Server.MapPath("~/counter.xml"));
Label1.Text = tmpDS.Tables[0].Rows[0]["hits"].ToString();
}
private void HitCount()
{
DataSet tmpDS = new DataSet();
tmpDS.ReadXml(HttpContext.Current.Server.MapPath("~/counter.xml"));
int hits = Int32.Parse(tmpDS.Tables[0].Rows[0]["hits"].ToString());
if (Session.IsNewSession == true)
{
hits += 1;
}
tmpDS.Tables[0].Rows[0]["hits"] = hits.ToString();
tmpDS.WriteXml(HttpContext.Current.Server.MapPath("~/counter.xml"));
}
}
}
l 在counter.ascx 前台添加一个 Lable控件 ID="Label1"
..
OK, enjoy it.. That is it..
