C# Programming Language: Queue

Hi everyone, welcome back. In this tutorial, we will be going over the Queue and how to use the built in functions regarding them. A Queue is a linear type of data structure that is capable of storing objects. The Queue is a first-in-first-out or FIFO data structure which means that the first item added to the queue is the first item that will be removed. With this introduction out of the way, let’s get into it.

Creating The Queue

Let’s start by creating a Queue. Before we can create the Queue, we need to make sure we have our necessary imports, which will be included within the System.Collections.Generic package:

using System.Collections.Generic;

Now, we can successfully create our Queue:

Queue<int> myQueue = new Queue<int>();

So now, we have created our Queue variable of the ‘int’ data type and named it myQueue. When we create our Queue, we need to specify the data type. As we can see in the example above, we have used the ‘int’ data type. We can use other data types as well, such as the string or boolean data types.

Adding Elements to The Queue

Now, let’s see how we can add elements into our Queue. We can do this by using the built in Enqueue() function that is provided. Let’s see…
