How to use C# Stack Class

Hi Friends, let me give you a intro about “Stack”. It is a last-in-first-out (LIFO) collection of objects. When you add an item in the list, it is called Push and when you remove it, it is called Pop. We will see How to use C# Stack Class.

Namespace :


using System.Collections;

Step1 :

Step4 :

Lets, Build simple console application to Push, Pop and  Display items from Stack.

Main Method :


private static bool flag = true;

private static Stack stackTable = new Stack();

static void Main(string[] args)

{

while (flag)

{

Console.WriteLine("\n1. Push \t2. Pop \n3. Display\t4. Exit");

Console.Write("Please enter your Choice: ");

string choice = Console.ReadLine();

switch (choice)

{

case "1":

stackTable = Push(stackTable);

break;

case "2":

stackTable = Pop(stackTable);

break;

case "3":

Display(stackTable);

break;

case "4":

flag = false;

break;

default:

Console.WriteLine("Enter correct choice !!");

break;

}

}

}

Output :

Push :


private static Stack Push(Stack stackTable)

{

Console.Write("Enter value into Stack Table : ");

string stackValue = Console.ReadLine();

stackTable.Push(stackValue);

Display(stackTable);

return stackTable;

}

Output :

Pop :


private static Stack Pop(Stack stackTable)

{

string stackValue = stackTable.Pop().ToString();

Console.WriteLine("Removed value form Stack Table : " + stackValue);

Display(stackTable);

return stackTable;

}

Output :

Display :


private static void Display(Stack stackTable)

{

var item = stackTable.GetEnumerator();

Console.WriteLine("Object in Stack Table :");

while(item.MoveNext())

{

Console.WriteLine(item.Current);

}

}

Output :

Returns the object at the top of the Stack without removing it.

etc.

Enjoy to Code..;)
