How to use C# Stack Class

The Stack class represents a last-in-first-out (LIFO) Stack of Objects. Stack follows the push-pop operations. That is we can Push (insert) Items into Stack and Pop (retrieve) it back . Stack is implemented as a circular buffer. It follows the Last In First Out (LIFO) system. That is we can push the items into a stack and get it in reverse order. Stack returns the last item first. As elements are added to a Stack, the capacity is automatically increased as required through reallocation.

Commonly used methods :

  Push : Add (Push) an item in the Stack data structure
  Pop : Pop return the last Item from the Stack

  Contains: Check the object contains in the Stack

Push : Add (Push) an item in the Stack data structure

  Syntax : Stack.Push(Object)
  Object : The item to be inserted.
  Stack days = new Stack();

  days.Push("Sunday");

Pop : Pop return the item last Item from the Stack

  Syntax : Object Stack.Pop()
  Object : Return the last object in the Stack

  days.Pop();

Contains : Check the object contains in the Stack

  Syntax : Stack.Contains(Object)
  Object : The specified Object to be search

  days.Contains("Tuesday");
