Learning design patterns, there has been no chance to write a singleton pattern.

Today in the console application, write a simple example, hi and hello.

  Public Sealed classAt {Private Staticat instance =NULL;  Public StaticAt Instance {Get            {                if(Instance = =NULL) {instance=NewAt (); }                returninstance; }        }         Public voidHello () {Console.WriteLine ("Hello"); }         Public voidHi () {Console.WriteLine ("Hi"); }    }

Test:

The Singleton class, declared as sealed, means that other classes are prevented from inheriting from the class. The object is just itself.
