Question

What’s the difference between the System.Array.CopyTo() and System.Array.Clone()?

Answer 1

The Clone() method returns a new array (a shallow copy) object containing all the elements in the original array. The CopyTo() method copies the elements into another existing array. Both perform a shallow copy. A shallow copy means the contents (each array element) contains references to the same object as the elements in the original array. A deep copy (which neither of these methods performs) would create a new instance of each element’s object, resulting in a different, yet identical object.

So the difference are :

1- CopyTo require to have a destination array when Clone return a new array. 2- CopyTo let you specify an index (if required) to the destination array. 

Edit:

Remove the wrong example.
