Remarks

This method supports the System.Collections.ICollection interface. If implementing System.Collections.ICollection is not explicitly required, use Copy 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 Length.
