反射+抽象工厂模式(一)

1.抽象工厂模式：提供一个创建一系列相关或相互依赖对象的接口，而无需指定它们具体的类

2.反射：

例子：

webconfig部分：

< xml version="1.0" encoding="utf-8" >

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
/**/
using System.Reflection;//反射
using System.Configuration;

namespace 抽象工厂模式
{
class Program
{
static void Main(string[] args)
{
User user = new User();
Department department = new Department();
IUser iu = DataAccess.CreatUser();
iu.Insert(user);
iu.GetUser(1);

IDepartment id = DataAccess.CreatDepartment();
id.Insert(department);
id.Getdepartment(1);
Console.Read();
}
}
#region 公共属性
class User
{
private int _id;
public int ID
{
get { return _id; }
set { _id = value; }
}

private string _name;
public string Name
{
get { return _name; }
set { _name = value; }
}
}

class Department
{
private int _id;
public int ID
{
get { return _id; }
set { _id = value; }
}

private string _deptName;
public string DeptName
{
get { return _deptName; }
set { _deptName = value; }
}
}
