C# Tutorial For Beginners: Working with collections(Stack)

It represents a last-in, first-out collection. It is used to create an array that supports the logic of last-in, first-out of elements. This article will provide code examples for its main properties and methods.

Note: the syntax of adding and removing items in the list, we will use the ‘push’ (add item) and ‘popping’ (remove item).

class Program

{

static void Main(string[] args)

{

//Creating a new stack

Stack StackLearning = new Stack();

//Adding elements

StackLearning.Push("st_1");

StackLearning.Push("st_2");

StackLearning.Push("st_3");

StackLearning.Push("st_4");

//Remove the top element in the stack

StackLearning.Pop();//will remove "st_4"

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

StackLearning.Pop();

//Determines whether an element is in the Stack.

Console.WriteLine(StackLearning.Contains("st_3"));//Returns True

//Remove all objects from the stack

StackLearning.Clear();

}
