what is single pattern term in c#
Make the class of the single instance responsible for access and initialization on first use. The single instance is a private static attribute. The accessor function is a public static method. The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance. It is named after the singleton set, which is defined to be a set containing one element. The office of the President of the United States is a Singleton.
