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

using System;

using System.Web;

using System.ComponentModel;

using System.ComponentModel.DataAnnotations;

namespace MvcApplication2.Models

{

[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")]

}

}

//////////////////调用

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

return View(list1);
