aspx页面

using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
public partial class AddBrow : System.Web.UI.Page
{
    public string tableName;
    public string item;
    public int classID;
    public int hot=0;

protected void Page_Load(object sender, EventArgs e)
{

        classID = int.Parse(Request.QueryString["cid"].ToString());

        addbrows();
    }

    public void addbrows()
    {
        DB ydy = new DB();
        SqlConnection ydyconn = ydy.getcon();
        ydyconn.Open();
        SqlCommand ydycom = new SqlCommand("Article set Hot=Hot+1 where id='" + classID + "' ", ydyconn);
        ydycom.ExecuteNonQuery();
        ydyconn.Close();

        ydyconn.Open();
        SqlCommand ydycomd = new SqlCommand("select * from Article where id='" + classID + "' ", ydyconn);
        SqlDataReader ydydr = ydycomd.ExecuteReader();
        while (ydydr.Read())
        {
            hot = ydydr.GetInt32(8);
            Response.Write(hot);
        }

}

注意：var url="articleAddBrow.aspx?cid=180";//是向页面articleAddBrow.aspx传值，将cid=180换成cid=$$article_id$$生成页面是用数据替换模板，就ok

Response.Write(hot); 输出使能够得到请求的值。

通过以上的例子拓展，可以写一个静态页中上下篇的问题！
