#614 – Subclass Accessibility

A class can be defined with one of two different levels of accessibility:

  • public – all code can use the class
  • internal – only code in the same .exe or .dll can use the class

When you define a subclass, the accessibility of the subclass must be the same as, or less accessible than, the parent class.

This means:

  • If the parent class is public
    • Subclass can be public or internal
  • If the parent class is internal
    • Subclass must be internal
