WebForm gets the data of the entity class and fills the page (use session to pass value)_html/css_WEB-ITnose

First create an entity class User

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace 实体类{    public class User    {               public int Id { get; set; }        public string UserName { get; set; }        public int Age { get; set; }        public int Gender { get; set; }    }}

Call SqlHelper to convert the queried data into a list object (map the queried data to the entity class)

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Data;namespace 实体类.ModelService{    public class UserService    {        public static List<user>  SelectDataToEntity()        {            //通过查询数据库，将获取到的数据转换成一个list            List<user> list = SqlHelper.SelectDataToList<user>("select * from T_User");            return list;                    }    }}</user></user></user>

WebForm1.aspx.cs page (Note: WebForm1.aspx page inherits the WebForm1.aspx.cs class)

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using 实体类.ModelService;namespace 实体类{    public partial class WebForm1 : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            //将获取到的list（List<user> lsit）存放到 Session里。然后可以在WebForm1.aspx页面中来遍历这个list 从而取到实体类的数据            Session.Add("User", UserService.SelectDataToEntity());        }    }}</user>
