A clone makes a copy of the arraylist. While an array is a reference type,
are only the references copied. Any change in a shadow will affect on the
other one as well. Except when it is by instance the removing or adding of a
reference (row), than they grew apart.

A copyto makes a copy of the values in a one dimensional array. Where when
it are objects it is in fact again a shadow of course.

A deep copy makes new copy of all the values and creates a new arraylist
arround those. For that I have never seen a method in Net. You have to do it
yourself. (In my opinion can that be complicated when it is by instance a
jagged array).

I hope this gives some idea's
