一般处理程序UserList.ashx代码
<%@ WebHandler Language="C#" Class="UserList" %>
using System;
using System.Web;
using System.Configuration;
using System.Data.SqlClient;
using System.Data;
using System.Text;
using System.IO;
public class UserList : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/html";
//第一步连接数据库
using(SqlConnection conn = new SqlConnection(GetConnStr()))
{
//第二部建立桥梁
string sql="SELECT * FROM Employee";
using(SqlDataAdapter da =new SqlDataAdapter(sql,conn))
{
//第三步建立DataTable自动打开连接并且把数据添加到内存表中
DataTable dt = new DataTable();
da.Fill(dt);
//开始遍历表，并且把值组装成字符串
StringBuilder sb =new StringBuilder();
if(dt.Rows.Count>0)//判断是否有记录
{
for(int i=0;i<dt.Rows.Count;++i)//遍历记录
{
sb.AppendFormat("<tr><td>{0}</td><td>{1}</td><td>{2}</td><td>{3}</td><td><a href=‘ShowList.ashx?id={0}‘>详细</a>---修改---删除</td><tr>",dt.Rows[i]["EmpId"],dt.Rows[i]["EmpName"],dt.Rows[i]["EmpAge"],dt.Rows[i]["DelFlag"]);
}
}
//读取并获取模版路径
string htmlPath=context.Server.MapPath("UserList.htm");
//读取模版内容
string strHtml=File.ReadAllText(htmlPath);
//将模版内容替换成字符串对象中的内容
strHtml=strHtml.Replace("$tbody",sb.ToString());
context.Response.Write(strHtml);
}
}
}
/// <summary>
/// 返回数据库的连接字符串
/// </summary>
/// <returns></returns>
public string GetConnStr()
{
string ConnStr=ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString;
return ConnStr;
}
public bool IsReusable {
get {
return false;
}
}
}
数据库连接字符串配置web.config
