public int ID

interface IDepartment

Department GetDepartment(int id);
}
class SqlserverDepartment : IDepartment
{
public void Insert(Department department)
{
Console.WriteLine("在SQL Server中给Department表增加一条记录");
}
public Department GetDepartment(int id)
{
Console.WriteLine("在SQL Server中根据ID得到Department表一条记录");
return null;
}
}
class AccessDepartment : IDepartment
{
public void Insert(Department department)
{
Console.WriteLine("在Access中给Department表增加一条记录");
}
public Department GetDepartment(int id)
{
Console.WriteLine("在Access中根据ID得到Department表一条记录");
return null;
}
}
interface IFactory
{
IDepartment CreateDepartment();
}
class SqlserverFactory : IFactory
{
public IDepartment CreateDepartment()
{
return new SqlserverDepartment();
}
}
class AccessFactory : IFactory

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
