原型模式（Prototype）是一种通过定义一个原型对象，然后通过复制该原型对象来创建新对象的设计模式。这种方式可以避免直接使用类的实例化操作，从而隐藏对象创建的细节并提升性能。

基本实现：

abstract class Prototype
{
    private string id;
    
    public Prototype(string id)
    {
        this.id = id;
    }
    
    public string Id
    {
        get
        {
            return id;
        }
    }
    
    public abstract Prototype Clone();
}

class ConcretePrototype1 : Prototype
{
    public ConcretePrototype1(string id) : base(id)
    {
    }
    
    public override Prototype Clone()
    {
        return (Prototype)this.MemberwiseClone();
    }
}

浅拷贝示例：

static void Main(string[] args)
{
    ConcretePrototype1 p1 = new ConcretePrototype1("I");
    ConcretePrototype1 C1 = (ConcretePrototype1)p1.Clone();
    Console.WriteLine("Cloned:{0}", C1.Id);
    Console.Read();
}

深拷贝实现：

class WorkExperience : ICloneable
{
    public string WorkData { get; set; }
    public string Company { get; set; }
    
    public object Clone()
    {
        return this.MemberwiseClone();
    }
}

class Resume : ICloneable
{
    private string name;
    private string sex;
    private string age;
    private WorkExperience work;
    
    public Resume(string name)
    {
        this.name = name;
        this.work = new WorkExperience();
    }
    
    private Resume(WorkExperience work)
    {
        this.work = (WorkExperience)work.Clone();
    }
    
    public void SetPersonalInfo(string sex, string age)
    {
        this.sex = sex;
        this.age = age;
    }
    
    public void SetWorkExperience(string workData, string company)
    {
        work.Company = company;
        work.WorkData = workData;
    }
    
    public void Display()
    {
        Console.WriteLine("{0},{1},{2}", name, sex, age);
        Console.WriteLine("工作经历:{0},{1}", work.WorkData, work.Company);
    }
    
    public object Clone()
    {
        Resume obj = new Resume(work);
        obj.name = this.name;
        obj.sex = this.sex;
        obj.age = this.age;
        return obj;
    }
}

深拷贝测试：

static void Main(string[] args)
{
    Resume a = new Resume("我是谁");
    a.SetPersonalInfo("男", "29");
    a.SetWorkExperience("2018-11-1", "杭州德川");
    
    Resume b = (Resume)a.Clone();
    b.SetWorkExperience("2020-2-09", "dahua");
    
    Resume c = (Resume)a.Clone();
    c.SetPersonalInfo("女", "23");
    c.SetWorkExperience("2021-9-08", "kaba");
    
    a.Display();
    b.Display();
    c.Display();
    
    Console.Read();
}
