What is a singleton? A singleton is a design pattern used when only one instance of an object is created and shared; that is, it only allows one instance of itself to be created. Any attempt to create another instance simply returns a reference to the first one. Singleton classes are created by defining all class constructors as private. In addition, a private static member is created as the same type of the class, along with a public static member that returns an instance of the class. Here is a basic example: public class SingletonExample { private static SingletonExample _Instance; private SingletonExample () { } public static SingletonExample GetInstance() { if (_Instance == null) { _Instance = new SingletonExample (); } return _Instance; } }
