Program.cs

using System;
using System.Collections.Generic;
using System.Text;

namespace AbstractFactory
{
    class Program
    {
        static void Main(string[] args)
        {
            Department dept = new Department();

            IFactory factory = new AccessFactory();

            IDepartment id = factory.CreateDepartment();
            id.Insert(dept);
            id.GetDepartment(1);

            Console.Read();
        }
    }
}

 

运行结果：

在Access中给Department表增加一条记录

在Access中根据ID得到Department表一条记录
