The study included 40 patients with viral hepatitis B. Blood samples were collected from each subject. Three sera were tested for HBeAg/HBsAg with ELISA technique, two of them for HBcAg with an indirect immunofluorescence method. Serum HBcAg was found in 35 (87.5%) of the patients with viral hepatitis B, while HBeAg was detected in one (2.5%). Serum HBcAg was found in two out of three patients with chronic active hepatitis (66.7%). The presence of HBcAg in the liver biopsies was detected in 37 (92.5%) of the patients with HBcAg in the serum.Q:

How to access an object’s protected constructor from a child class?

I have this class:
public class SomeClass : ParentClass
SomeOtherClass obj = new SomeOtherClass();

// SomeCode

In the child class SomeOtherClass, I’d like to access the constructor of the parent class. The problem is, that the compiler doesn’t allow me to do so. What would be the best way to solve this problem? Thanks.


By definition of the language, a child class doesn’t have access to the constructor of a parent class unless it’s stated explicitly in the child class.
In your case, this would imply that the SomeClass can’t know about the parent class’s constructor.

The problem is, that the compiler doesn’t allow me to do so. What would be the best way to solve this problem?

The most simple way to deal with this would be to encapsulate the construction in the child class, and let the constructor of the parent class get the input from the child class.
public class SomeClass
// Encapsulate the construction of SomeOtherClass
SomeOtherClass(some_input_to_construct_child_class) { }

SomeOtherClass obj = new SomeOtherClass(some_input_to_construct_child_class);

// SomeCode


How about just creating a constructor on the parent class that takes an object and then create an explicit interface on the class that the child class can use to invoke this constructor? I.e.:
public class ParentClass
public ParentClass(SomeOtherClass someOtherClass) {…}

public class SomeClass : ParentClass
public SomeClass() : base(new SomeOtherClass()) {…}
