When the base class has a method private virtual int XX (int A) {return a + 1} If the subclass uses new such as private New int XX (int A) {return a + 2}, the virtual functions in the base can be hidden. If the XX (1) method in the subclass is called at this time, the result is 2. However, in the subclass, you can still use base. XX (1) to call the XX method of the base class. If override such as private overrid
