継承メモ

When you create a class without explicitly inheriting from another class, your class implicitly inherits from System.Object.

自分で作ったクラスに何も継承させなかったときは、System.Objectを継承する

Public Class Class2
             Inherits Class1
  ' class member declarations go here
End Class
'' ↑改行は:で置き換え可能↓
Public Class Class2 : Inherits Class1
  ' class member declarations go here
End Class
