A collection of > Queue Queue > Create a queue

The System.Collections.Queue class provides four overloaded constructors.

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // Construct using the default constructor Queue
            Queue qu = new Queue();
            qu.Enqueue(" Elements of the queue 1");
            qu.Enqueue(" Elements of the queue 2");
            qu.Enqueue(null);
            // Using the implementation ICollection The class instance of the interface, here is the list of arrays, constructed Queue
            Queue qu2 = new Queue(new string[5] { " Elements of the queue 1", " Elements of the queue 2", " Elements of the queue 3", " Elements of the queue 4", " Elements of the queue 5" });
            // Use the initial capacity of 20 Individual element structure Queue.
            Queue qu3 = new Queue(20);
            // Use the initial capacity of 20 And the equal ratio factor is 2 To construct the Queue.
            Queue qu4 = new Queue(20, 2);
        }
    }
   
}

The isometric factor means that the current capacity is 5, and the isometric factor is 2 when the capacity is expected to be expanded to 10.

The default capacity of Queue is 32 elements.
