设计模式-原型模式

Prototype Pattern

原型实例指定创建对象的种类，并且通过拷贝这些原型创建新的对象。

 

    abstract class Prototype
    {
        private string id;

        // Constructor
        public Prototype(string id)
        {
            this.id = id;
        }

        // Property
        public string Id
        {
            get { return id; }
        }

        public abstract Prototype Clone();
    }

    class ConcretePrototype1 : Prototype
    {
        // Constructor
        public ConcretePrototype1(string id)
            : base(id)
        {
        }

        public override Prototype Clone()
        {
            // Shallow copy
            return (Prototype)this.MemberwiseClone();
        }
    }

    class ConcretePrototype2 : Prototype
    {
        // Constructor
        public ConcretePrototype2(string id)
            : base(id)
        {
        }

        public override Prototype Clone()
        {
            // Shallow copy
            return (Prototype)this.MemberwiseClone();
        }
    } 

 

ConcretePrototype1 p1 = new ConcretePrototype1("I");
ConcretePrototype1 c1 = (ConcretePrototype1)p1.Clone();
Console.WriteLine("Cloned: {0}", c1.Id);

ConcretePrototype2 p2 = new ConcretePrototype2("II");
ConcretePrototype2 c2 = (ConcretePrototype2)p2.Clone();
Console.WriteLine("Cloned: {0}", c2.Id);
