Requirement: When class needs to have only one instance, and there should be a global point of access to the instance.
class Singleton
{
private static Singleton instance;
private Singleton() {}
public static Singleton Instance
{
get
{
if (instance == null)
{
instance = new Singleton();
}
return instance;
}
}
}
Constructor is made private so that the class cannot be instantiated with keyword new.
To create the object:
Singleton s1 = Singleton.Instance;
