原型模式实例简历浅复制 深复制

把一份简历复制成多份浅复制实现 

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication6
{
    class Resume:ICloneable
    {private string name;
        private string sex;
        private string age;
        private string timearea;
        private string company;
        public Resume(string name)
        {
            this.name = name;
        }
        public void setinfo(string sex,string age)
        {
            this.sex = sex;
            this.age = age;
        }
        public void setexperience(string timearea,string company)
        {
            this.timearea = timearea;
            this.company = company;
        }
        public void display()
        {
            Console.WriteLine("{0} {1}{2}", name, sex, age);
            Console.WriteLine("工作经历：{0}{1}", timearea, company);
            
        }
        public object Clone()
        {
            return (Object)this.MemberwiseClone();
        }
    }
}

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication6
{
    class Program
    {
        static void Main(string[] args)
        {
            Resume a = new Resume("大鸟");
            a.setinfo("男","29");
            a.setexperience("1998-2000", "xx公司");
            Resume b = (Resume)a.Clone();
            b.setexperience("2001-2004", "xx公司");
            Resume c = (Resume)a.Clone();
            c.setinfo("男", "22");
            a.display();
            b.display();
            c.display();
        }
    }
}

如果把工作经历设成一个类，就不能通过浅复制来实现，因为浅复制不能复制对对象的引用，复制的简历都指向同一地址。必须进行深复制

工作经历类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication6
{
    class WorkExperience:ICloneable
    {
        private string workdate;
        public string WorkDate
        {
            get { return workdate; }
            set { workdate = value; }
        }
        private string company;
        public string Company
        {
            get { return company; }
            set { company = value; }
        }
        public Object Clone()
        {
            return (Object)this.MemberwiseClone();
        }

    }
}

 简历类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication6
{
    class Resume:ICloneable
    {private string name;
        private string sex;
        private string age;
        WorkExperience work;
        public Resume(string name)
        {
            this.name = name;
            work = new WorkExperience();
        }
        private Resume(WorkExperience work)
        {
            this.work = (WorkExperience)work.Clone();

        }
        public void setinfo(string sex,string age)
        {
            this.sex = sex;
            this.age = age;
        }
        public void setexperience(string timearea,string company)
        {
            work.WorkDate = timearea;
            work.Company = company;
        }
        public void display()
        {
            Console.WriteLine("{0} {1}{2}", name, sex, age);
            Console.WriteLine("工作经历：{0}{1}", work.WorkDate,work.Company);
            
        }
        public object Clone()
        {
            Resume obj = new Resume(this.work);
            obj.name = this.name;
            obj.sex = this.sex;
            obj.age = this.age;
            return obj;
        }
    }
}
