This method copies all the elements of the current array instance to the array destination array, starting at index index. The array destination array must already have been dimensioned and must have a sufficient number of elements to accommodate the copied elements. Otherwise, the method throws an exception.

This method supports the ICollection interface. If implementing ICollection is not explicitly required, use Array.Copy(Array, Array, long) to avoid an extra indirection.

If this method throws an exception while copying, the state of array is undefined.

This method is an O(n) operation, where n is Array.Length. It performs a shallow copy only.
