Can you have a private constructor C#?

1. Static constructor is called before the first instance of class is created, wheras private constructor is called after the first instance of class is created . 2. Static constructor will be executed only once, whereas private constructor is executed everytime, whenever it is called.

Private constructors are used to prevent creating instances of a class when there are no instance fields or methods , such as the Math class, or when a method is called to obtain an instance of a class. If all the methods in the class are static, consider making the complete class static.

Yes, we can declare a constructor as private . If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.
