Explain how to Implement an Object Pool in C#.NET.

using System;
using System.Collections;

namespace ObjectPool
{
      class ObjQueue
      {
           private static int maxSize = 2;
           private static readonly Queue objPool = new Queue(maxSize);
           public MyClass GetMyClass()
           {
              MyClass oMyClass;
              if (MyClass.Counter >= maxSize && objPool.Count>0)
                   oMyClass = RetrieveFromPool();
              else
                   oMyClass = GetNewMyClass();
                   return oMyClass;
           }
           private MyClass GetNewMyClass()
           {
               MyClass myObj = new MyClass();
               objPool.Enqueue(myObj);
               return myObj;
           }
           protected MyClass RetrieveFromPool()
           {
               MyClass myObj;
               if (objPool.Count>0)
               {
                   myObj = (MyClass)objPool.Dequeue();
                   MyClass.Counter--;
              }
              else
                   myObj = new MyClass();
                   return myObj;
          }
}
class MyClass
{
          public static int Counter = 0;
          public MyClass() { ++Counter; }
          private string _Firstname;
          public string Firstname
          {
               get { return _Firstname; }
               set { _Firstname = value; }
          }
}}
