C# - 使用 List<> 泛型给GridView控件数据

namespace Test.Models
{
    public class Student
    {
        public string ID
        {
            get;
            set;
        }

        public string Name
        {
            get;
            set;
        }
    }
}

using System;
using System.Data;
using System.Collections.Generic;

namespace Test
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            List<Models.Student> studentlist = new List<Models.Student>();
            string sql = string.Format("select ID, Name from Tb_Student where Sex = {0}", 1);
            DataTable dt = new DataTable();
            dt = DAL.SQLHelper.ExecuteTable(sql, CommandType.Text);
            if (dt != null || dt.Rows.Count >0)
            {
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    Models.Student student = new Models.Student
                    {
                        ID = dt.Rows[i]["ID"].ToString(),
                        Name = dt.Rows[i]["Name"].ToString()
                    };
                    studentlist.Add(student);
