【C#】Deep copy of objects

If you learned C++ carefully, you must have known something about the copy of object.

For example, I defined a class called (ABC)，and two variable (x) and (y) are (ABC)s.

Like this:

class ABC{
    public:
        int a,b;
};
int main(){
    ABC x,y;
    x.a=1;x.b=2;
    y=x;
    y.a=3;
    return 0;    
};

Certainly,( y.a==3 , y.b==2 ), and, what's more,  ( x.a==1,x.b==2 ).

So in fact,a deep copy was made in the line 8.

But in C#,this can be different, if you operate like this, ( x.a==3,x.b==2 ) would be the result, for x and y is the same variable.

So how can we make a deep copy? Do not worry,we can serialize it and then turn it back!

(Remember : Don't forget to put a ([Serializable]) before the defination of the object!!!)
