what is the use of private constructor?

Answer:

When we declare a class constructor as private , we can not do 2 things:-

-- We can not create a object of the class from out side of the class.
-- We can not inherit the class.

Private constructor is used for controlling the object generation which Is singleton design pattern implementation..

public class Singleton

{

 private static Singleton instance = new Singleton();

//Private constructor, which does not allow object creation

//from outside the classs..

 private Singleton() { }

 

 public static Singleton GetInstance

 {

 get

 {

 return instance;

 }

 }

}
