深复制——Deep_Copy

简历的深复制实现

workExperience类:实现了ICloeable接口==实现了Clone方法——创建一个新对象，然后将当前对象的非静态字段复制到该新对象。如果字段是值类型的则对该字段执行逐位复制。如果字段是引用类型的，则复制引用但不复制引用的对象。

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

namespace Deep_Copy
{
    class WorkExperience : ICloneable
    {
        private string workDate;
        public string WorkDate
        {
            get { return workDate; }
            set { this.workDate = value; }
        }
        private string company;
        public string Company
        {
            get { return company; }
            set { this.company = value; }
        }

        public object Clone()
        {
            return (Object)this.MemberwiseClone();
        }
    }
}

Resume简历

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

namespace Deep_Copy
{
    class Resume : ICloneable
    {
        private string name;
        private string sex;
        private string age;
        private WorkExperience workExperience;
        public Resume(string name)
        {
            this.name = name;
            workExperience = new WorkExperience();
        }
        private Resume(WorkExperience workExperience)
        {
            this.workExperience = (WorkExperience)workExperience.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)
        {
            this.workExperience.WorkDate = workDate;
            this.workExperience.Company = company;
        }
        //显示
        public void DisPlay()
        {
            Console.WriteLine("{0} {1} {2}", name, sex,age);
            Console.WriteLine("工作经历: {0} {1}",workExperience.WorkDate,workExperience.Company);
        }
        public Object Clone()
        {
            Resume obj = new Resume(this.workExperience);
            obj.name = this.name;
            obj.sex = this.sex;
            obj.age = this.age;
            return obj;
        }
        
    }
}

深复制：把引用对象的变量指向复制过的新对象，而不是原有的被引用的对象。当Resume类的对象new出来时候共有的Resume方法new了一个WorkExperience对象存储到Resume对象中的workExperience。

Resume对象中的Clone方法 调用私有构造器Resume()将workExperience传入到私有构造器中，在私有构造器中调用workExperienc中的Clone方法。 返回的WorkExperience对象存储在workExperiecne中。这个时候相当于把引用对象的变量指向了复制过来的新对象obj 而不是原有的被引用的对象。
