简历实例

（一）浅拷贝

1.简历实例

 public class Remuse : ICloneable
    {
        private string name;
        private string sex;
        private string age;

        private WorkExperience work;

        public Remuse(string name)
        {
            this.name = name;
            work = new WorkExperience();
        }

        //设置个人信息
        public void SetPersonalInfo(string sex, string age)
        {
            this.sex = sex;
            this.age = age;
        }

        //设置工作经历
        public void SetWorkExperience(string workDate, string company)
        {
            work.WorkDate = workDate;
            work.Company = company;
        }

        //显示
        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()
        {
            return (object)this.MemberwiseClone();
        }
    }

2.工作经验

public class WorkExperience
    {
        private string workDate;

        public string WorkDate
        {
            get { return workDate; }
            set { workDate = value; }
        }

        private string company;

        public string Company
        {
            get { return company; }
            set { company = value; }
        }
    }

3.调用

            Remuse a = new Remuse("大鸟");
            a.SetPersonalInfo("男", "29");
            a.SetWorkExperience("1998-2000", "XX公司");

            Remuse b = (Remuse)a.Clone();
            b.SetWorkExperience("1998-2006", "YY企业");

            Remuse c = (Remuse)a.Clone();
            c.SetPersonalInfo("男", "24");

            a.Display();
            b.Display();
            c.Display();

（二）深拷贝

1.简历

 public class RemuseDeep : ICloneable
    {
        private string name;
        private string sex;
        private string age;

        private WorkExperienceDeep work;

        public RemuseDeep(string name)
        {
            this.name = name;
            work = new WorkExperienceDeep();
        }

        private RemuseDeep(WorkExperienceDeep work)   //提供Clone方法调用的私有构造函数，以便克隆工作经历数据，
        {
            this.work = (WorkExperienceDeep)work.Clone();
        }

        //设置个人信息
        public void SetPersonalInfo(string sex, string age)
        {
            this.sex = sex;
            this.age = age;
        }

        //设置工作经历
        public void SetWorkExperience(string workDate, string company)
        {
            work.WorkDate = workDate;
            work.Company = company;
        }

        //显示
        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()
        {
            RemuseDeep obj = new RemuseDeep(this.work);   //调用私有构造函数，克隆工作经历，在给简历相关字段赋值，最终返回深复制简历对象，

            obj.name = this.name;
            obj.sex = this.sex;
            obj.age = this.age;

            return obj;
        }
    }

2.工作经验

 public class WorkExperienceDeep: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()   //工作经历类实现Clone方法，
        {
            return (Object)this.MemberwiseClone();
        }

    }

3.调用

            RemuseDeep ad = new RemuseDeep("大鸟");
            ad.SetPersonalInfo("男", "29");
            ad.SetWorkExperience("1998-2000", "XX公司");

            RemuseDeep bd = (RemuseDeep)ad.Clone();
            bd.SetWorkExperience("1998-2006", "YY企业");

            RemuseDeep cd = (RemuseDeep)ad.Clone();
            cd.SetWorkExperience("1998-2003", "ZZ企业");

            ad.Display();
            bd.Display();
            cd.Display();
