public class Test
{
public string s;
}
...
private void test()
{
Test[] array = new Test[1];
array[0] = new Test();
array[0].s = "ORIGINAL";
Test[] copy = new Test[1];
array.CopyTo(copy, 0);
// Next line displays "ORIGINAL"
MessageBox.Show("array[0].s = " + array[0].s);
copy[0].s = "CHANGED";
// Next line displays "CHANGED", showing that
// changing the copy also changes the original.
MessageBox.Show("array[0].s = " + array[0].s);

Hi
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 would create a new instance of each element's object, resulting in a different, yet identacle object.
Hope this is clear enough.
Best regards
