浅拷贝

浅拷贝是字段的被拷贝，而字段的引用的对象不会被拷贝，拷贝对象和源对象仅仅是引用名称有所不同，他们公用一份实体,改变其中一个都会影响到因为一个对象。

void Main(){     Student s1=new Student("objectboy",27);    Student s2=s1;    s2.Age=20;    s1.ShowInfo();    s1.Age=11;    s2.ShowInfo();}public class Student{    public string Name;    public int Age;    public Student(string name,int age){        Name=name;        Age=age;    }    public void ShowInfo(){        Console.WriteLine("{0}'s age is {1} ",Name,Age);    }}

输出：objectboy's age is 20 objectboy's age is 11

 深拷贝

对象的字段拷贝，同时对象的引用也被拷贝，不共用一个对象，改变其中一个对象不会影响到另外一个对象(一般值类型的拷贝就是深拷贝)。

void Main(){    int i=0;    int j=i;    i=2;    Console.WriteLine(i);    Console.WriteLine(j);}

输出：20

 浅拷贝实现

void Main(){    var sourceEnrollment=new Enrollment();    sourceEnrollment.students.Add(new Student(){Name="objectboy",Age=27});    sourceEnrollment.students.Add(new Student(){Name="hky",Age=27});        Enrollment cloneStudents=sourceEnrollment.Clone() as Enrollment;  //克隆    sourceEnrollment.ShowEnrollmentInfo();    cloneStudents.ShowEnrollmentInfo();        Console.WriteLine("------------------------------");        cloneStudents.students[0].Name="boyobject";    cloneStudents.students[0].Age=22;    sourceEnrollment.ShowEnrollmentInfo();    cloneStudents.ShowEnrollmentInfo();}class Enrollment:ICloneable{    public  List
     
       students=new List
      
       ();    public void ShowEnrollmentInfo(){        foreach (var element in students)        {            Console.WriteLine("{0}'s age is {1}",element.Name,element.Age);        }    }    public object Clone(){        return MemberwiseClone();    }}public class Student{    public string Name{
   get;set;}    public int Age{
   get;set;}}
      
     

输出:objectboy's age is 27hky's age is 27objectboy's age is 27hky's age is 27------------------------------boyobject's age is 22hky's age is 27boyobject's age is 22hky's age is 27
