Creates a shallow copy of the ArrayList.
Assembly: mscorlib (in mscorlib.dll)
A shallow copy of a collection copies only the elements of the collection, whether they are reference types or value types, but it does not copy the objects that the references refer to. The references in the new collection point to the same objects that the references in the original collection point to.
In contrast, a deep copy of a collection copies the elements and everything directly or indirectly referenced by the elements.
This method is an O(n) operation, where n is Count.
