Stack<(Of <(T>)>) the ToArray method.
'Use the Push method to push five strings onto the stack.
'The elements of the stack are enumerated, which does not change the state of the stack.
'The Pop method is used to pop the first string off the stack.
'The Peek method is used to look at the next item on the stack
'The ToArray method is used to create an array and copy the stack elements to it
