在用户列表中链接数据库 在这里html只管做Post 请求,其他逻辑全部交给ashx 其中修改需要隐藏域

1.展现列表

 1  public void ProcessRequest (HttpContext context) {
 2         context.Response.ContentType = "text/html";
 3         //连接数据库
 4         string connString = System.Configuration.ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
 5 
 6         using (SqlConnection conn = new SqlConnection(connString))
 7         {
 8             using(SqlDataAdapter apter=new SqlDataAdapter("select * from UserInfo",conn))
 9             {
10                 DataTable da = new DataTable();
11                 apter.Fill(da);
12                 //
13                 StringBuilder sb = new StringBuilder();
14                 for (int i = 0; i < da.Rows.Count; i++)
15                 {
16                     sb.AppendFormat("<tr><td>{0}</td><td>{1}</td><td>{2}</td><td>{3}</td><td>{4}</td><td><a href=‘ShowDetail.ashx?id={5}‘>详细</a></td></tr>",
17                             da.Rows[i]["ID"], da.Rows[i]["UserName"], da.Rows[i]["UserPass"],Convert.ToDateTime(da.Rows[i]["RegTime"]).ToShortDateString(),
18                             da.Rows[i]["Email"],da.Rows[i]["ID"]);
19                 }
20                 string filePath = context.Request.MapPath("UserInfoList.html");
21                 string fileContent = File.ReadAllText(filePath);
22                 fileContent= fileContent.Replace("$tbody",sb.ToString());//$tbody是html 里面的
23                 context.Response.Write(fileContent);
24             }
25         }
26     }

 

在这里的html里面指定AddUserInfo.html
