VB.NET Language in a Nutshell, Second Edition

Name

Stack.Pop Method

Class

System.Collections.Stack

Syntax

                  stackvariable.Pop(  )

Return Value

Object

Description

Removes the top item from the stack and returns it as an Object

Rules at a Glance

• Pop removes the top item from the stack and decrements the Count property by one.

• Pop generates an error if applied to an empty stack. Thus, it’s advisable to determine when a stack is empty by using the Count property before popping the stack.

Programming Tips and Gotchas

The Peek method returns a reference to the object at the top of the stack, but unlike the Pop method, does not remove it from the stack.
