Singleton

The singleton pattern is a software design pattern that is used to restrict instantiation of a class to one object. This is useful when we require exactly one object of a class to perform our operations. In this pattern we ensure that the class has only one instance and we provide a global point of access to this object public class Singleton { // Static object of the Singleton class. private static volatile Singleton _instance = null; ///

/// The static method to provide global access to the singleton object. ///

/// Singleton object of class Singleton. public static Singleton Instance() { if (_instance == null) { lock (typeof(Singleton)) { _instance = new Singleton(); } } return _instance; } ///

/// The constructor is defined private in nature to restrict access. ///

private Singleton() { } }
