Constructors generally cannot be private.

Generally we use constructors to create objects. If you place a constructor as private, you cannot create an object of that particular class. Thus any classes except the nested classes are allowed to create instance of it.

It is really a rare case to use Private Constructors. It is created to classes which have only static members, so that each member can individually be accessed without its object.

In that case that class will act like a sealed class. Am I correct??

Mark this as answer, if it is.....

Hi,

unlike as static class, class with private constructor is not implicitly sealed. you explicitly need to make it sealed otherwise you will get complie time error when try to derive class from that class.
