c# 利用反射动态给实体类对象赋值

转：http://blog.sina.com.cn/s/blog_659a572b0100xp5s.html

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

}





//////////////////调用



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

  return View(list1);
