Object[] toArray() Returns an array containing all of the elements in this collection. If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. ...
The Array class is not part of the System.Collections namespaces. However, it is still a collection because it is based on the IList interface. The rank of an Array object is the number of dimensions in the Array. An Array can have one or more ranks. The lower bound of an Array is ...
