求问模式达人，静态类可否代替单件？

哈哈哈~看代码：）想必单件模式大家都非常熟悉：）

namespace  Singleton1
{
     class  Program
    {
         static   void  Main( string [] args)
        {
             for  ( int  i  =   0 ; i  <   10 ; i ++ )
            {
                Factory.RecordCount();
            }

            Factory.Display();

            global::System.Console.Read();
        }
    }

     static   class  Factory
    {
         private   static   object  objLock  =   typeof (Factory);
         private   static   long  longCount  =   0 ;

         public   static   void  RecordCount()
        {
             lock  (objLock)
            {
                longCount ++ ;
            }
        }

         public   static   void  Display()
        {
             lock  (objLock)
            {
                global::System.Console.WriteLine(longCount);
            }
        }
    }
}
