例子如下


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcApplication2.Models;
using DataAccess;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Reflection;
namespace MvcApplication2.Controllers
{
   /// <summary>
    /// 将datatable装入指定类型的集合
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class GenericList<T>:List<T>
    {
        public GenericList(DataTable dt, string  f)
        {
            System.Type tt = System.Type.GetType(f);//获取指定名称的类型
            object ff = Activator.CreateInstance(tt, null);//创建指定类型实例
            PropertyInfo[] fields = ff.GetType().GetProperties();//获取指定对象的所有公共属性
            foreach (DataRow dr in dt.Rows)
            {
                object obj = Activator.CreateInstance(tt, null);
                foreach (DataColumn dc in dt.Columns)
                {
                    foreach (PropertyInfo t in fields)
                    {
                        if (dc.ColumnName == t.Name)
                        {
                            t.SetValue(obj, dr[dc.ColumnName], null);//给对象赋值
                            continue;
                        }
                    }

                }
                this.Add((T)obj);//将对象填充到list集合
            }
        }
    }

｝
//////////////////////实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
namespace MvcApplication2.Models
{
    [MetadataType(typeof(EmployeeData))]
    public partial  class Employee
    {

        public class EmployeeData
        {
            [DisplayName("用户ID")]
            public int ID { set; get; }

            [DisplayName("姓名")]
            [Required(ErrorMessage = "用户名不允许为空")]
            [StringLength(50, ErrorMessage = "用户名长度必须小于50个字符")]
            public string Uname { set; get; }

            [DisplayName("性别")]
            public bool Sex { set; get; }

            [DisplayName("出生日期")]
            [Required(ErrorMessage = "出生日期不允许为空")]
            public DateTime Birthday { set; get; }

            [DisplayName("是否婚配")]
            public bool IsHp { set; get; }

          
        }


    }
}


//////////////////调用

 GenericList<Employee> list1 = new GenericList<Employee>(dt, "MvcApplication2.Models.Employee");//调用
  return View(list1);
