Queue (Queue) represents a FIFO collection of objects. When you need access to the FIFO, then use the queue. When you add a list, called into the team , when you remove the item from the list, called a team .
Queue class of methods and properties
The following table lists Queue some common class attributes :
| Attributes | description |
|---|---|
| Count | Get the number of elements contained in the Queue. |
The following table lists Queue some common class method :
| No. | Methods Name & Description |
|---|---|
| 1 | public virtual void Clear (); removing all the elements from the Queue. |
| 2 | public virtual bool Contains (object obj) ; determining whether an element in the Queue. |
| 3 | public virtual object Dequeue (); remove the object and returns at the beginning of Queue. |
| 4 | public virtual void Enqueue (object obj) ; add an object to the end of the Queue. |
| 5 | public virtual object [] ToArray () ; Copy Queue to a new array. |
| 6 | public virtual void TrimToSize (); set a capacity of the actual number of elements in the Queue. |
Examples
The following example demonstrates the use of a queue (Queue) is:
Examples
using System;
using System.Collections;
namespace CollectionsApplication
{
class Program
{
static void Main(string[] args)
{
Queue q = new Queue();
q.Enqueue('A');
q.Enqueue('M');
q.Enqueue('G');
q.Enqueue('W');
Console.WriteLine("Current queue: ");
foreach (char c in q)
Console.Write(c + " ");
Console.WriteLine();
q.Enqueue('V');
q.Enqueue('H');
Console.WriteLine("Current queue: ");
foreach (char c in q)
Console.Write(c + " ");
Console.WriteLine();
Console.WriteLine("Removing some values ");
char ch = (char)q.Dequeue();
Console.WriteLine("The removed value: {0}", ch);
ch = (char)q.Dequeue();
Console.WriteLine("The removed value: {0}", ch);
Console.ReadKey();
}
}
}
When the above code is compiled and executed, it produces the following results:
Current queue: A M G W Current queue: A M G W V H Removing values The removed value: A The removed value: M
