Answer / bhagyesh

class A
{
public A()
{
};
public int i;
}
class TestPerson
{
static void Main()
{
A a = new A();
A b;
a.i =5;
b=a; // not a deep copy
b.i = a.i+6;
}
}
here a.i=11 and b.i = 11 because a and b both refer same
instance of object
Deep copy would be implemented in c# using copy construction
class A
{
public A()
{
};
public A(A previouscopy)
{
i = previouscopy.i;
};
public int i;
}
class TestPerson
{
static void Main()
{
A a = new A();
a.i =5;
// Create another new object, copying a.
A b = new A(a); // Deep copy using copy constructor
b.i = a.i+6;
}
}
here a.i=5 and b.i = 11 because a and b both refer it's own
instance of object

Answer / rad

public static T DeepCopy<T>(T obj)
{
object result = null;

using (var ms = new MemoryStream())
{
var formatter = new BinaryFormatter();
formatter.Serialize(ms, obj);
ms.Position = 0;

result = (T)formatter.Deserialize(ms);
ms.Close();
}

return (T)result;
}

In C# if u want to deep allocation, u can used
serialization that is use ISerializable
for shallow copy u can use cloning, that is use Iclonable
interface

Answer / mario j vargas

You can perform a deep copy in C# by implementing the
ICloneable interface and manually assigning the values of
each member field in the current instance to the new
instance being returned. It is important to mention in the
implementation's documentation whether or not the copy is a
shallow or deep copy.

Bhagyesh suggested using a copy constructor. This is
something I had never seen in C#, only in C++, but the idea
sounded very compelling and I think this could be another
way to achieve a deep copy. You should check out the article
"How to: Write a Copy Constructor (C# Programming Guide)" in
the MSDN documentation.

Answer / sanjay

I Agree clone() always gives deep copy.

Now I am just diverting from the tpoic. one of the question
asked during interview is : what is the difference b/w
Array.copy() and array.clone(). for me both gives deep copy
the only difference is array.clone() returns a object type
so you have to typecast it.
