What is the Queue class?

Rating:

The Queue is a data structure that stores a object in such a manner that the object inserted first is the first to come out. The queue is also called first in first out (FIFO) list. The two important methods used in the queue class are as follows:

  • Enqueue(): Inserts an object in the queue.
  • Dequeue(): Removes an object from the queue.
The following code snippet displays the use of the Queue class:

using System;
using System.Collections;
public class SamplesQueue
{
   public static void Main()
   {
      Queue MyQueue = new Queue();
      MyQueue.Enqueue("Microsoft");
      MyQueue.Enqueue("Corporation");
      MyQueue.Enqueue("Limited");
      PrintTheValues(myqueue);
   }
   public static void PrintTheValues(IEnumerable MyCollection)
   {
      foreach (Object list in MyCollection)
      Console.Write(list);
   }
}
