Q11. How can you implement Singleton or Factory in C#?


If a constructor is created with a private access modifier, then it is known as a Private Constructor. A private constructor is a special instance constructor that is generally used in classes that contain static members only.

If we do not use an access modifier with the constructor it will still be private by default. However, the private modifier is usually used explicitly to make it clear that the class cannot be instantiated.

Also a private constructor without having any parameters prevent the automatic generation of the default constructor.

A private constructor is generally used for the singleton implementation.
A class only having a default private constructor cannot be inherited.
Private constructors are used for preventing the instantiation of a class.
A class having only private constructors cannot be instantiated, except the nested class.
