學習筆記:設計模式之抽象工廠(C#)

標籤：建立   實體類   creat   設計模式   用戶端   return   int   ctf   class   

1.建立抽象工廠類

    public abstract class AbstractFactory    {        public abstract Connect CreatConnet();        public abstract Select CreatSelect();    }

2.建立兩個抽象類別

    public abstract class Connect    {        public abstract void Print();    }    public abstract class Select    {        public abstract void Print();    }

3.建立兩個實體類

    public class SqlConnect : Connect    {        public override void Print()        {            //throw new NotImplementedException();            Console.Write("Sql Connect");        }    }    public class SqlSelect : Select    {        public override void Print()        {            Console.Write("Sql Select");        }    }    public class MysqlConnect : Connect    {        public override void Print()        {            Console.Write("MySql Connect");        }    }    public class MysqlSelect : Select    {        public override void Print()        {            Console.WriteLine("MySql Select");        }    }

4.建立實體工廠類

    public class SqlFactory : AbstractFactory    {        public override Connect CreatConnet()        {            return new SqlConnect();        }        public override Select CreatSelect()        {            return new SqlSelect();        }    }    public class MySqlFactory : AbstractFactory    {        public override Connect CreatConnet()        {            return new MysqlConnect();        }        public override Select CreatSelect()        {            return new MysqlSelect();        }    }

5.用戶端調用

        static void Main(string[] args)        {            AbstractFactory sqlFactory = new SqlFactory();            AbstractFactory mysqlFactory = new MySqlFactory();            Connect sqlConnect = sqlFactory.CreatConnet();            Connect mysqlConnect = mysqlFactory.CreatConnet();            sqlConnect.Print();            mysqlConnect.Print();            Select sqlSelect = sqlFactory.CreatSelect();            Select mysqlSelect = mysqlFactory.CreatSelect();            sqlSelect.Print();            mysqlSelect.Print();                        Console.Read();        }
