淺拷貝 −
淺拷貝是指拷貝一個物件的"主要"部分，但不拷貝內部的部分 objects.
The "inner objects" are shared between the original object and its copy.
The problem with the shallow copy is that the two objects are not independent. If you 修改一個對象，改變將會反映在另一個對象。
深拷貝 −
深拷貝是完全獨立的物件副本。如果我們複製了我們的對象， would copy the entire object structure.
If you modify the one object, the change will not be reflected in the other object.
class Program{
static void Main(string[] args){
//Shallow Copy
ShallowCopy obj = new ShallowCopy();
obj.a = 10;
ShallowCopy obj1 = new ShallowCopy();
obj1 = obj;
Console.WriteLine("{0} {1}", obj1.a, obj.a); // 10,10
obj1.a = 5;
Console.WriteLine("{0} {1}", obj1.a, obj.a); //5,5
//Deep Copy
DeepCopy d = new DeepCopy();
d.a = 10;
DeepCopy d1 = new DeepCopy();
d1.a = d.a;
Console.WriteLine("{0} {1}", d1.a, d.a); // 10,10
d1.a = 5;
Console.WriteLine("{0} {1}", d1.a, d.a); //5,10
Console.ReadLine();
}
}
class ShallowCopy{
public int a = 10;
}
class DeepCopy{
public int a = 10;
}10 10 5 5 10 10 5 10
