User · Answer

You organized class interface such that public members begin with "my". Therefore you must use only those members. Instead of

myScoreonHole.hole = Console.ReadLine();

you should write

myScoreonHole.myhole = Console.ReadLine();

User · Answer

You need to use the public properties from Main  and not try to directly change the internal variables

User · Answer

In your Main method  you re trying to access  for instance  club  which is protected   when you should be accessing myclub which is the public property that you created

User · Answer

In your base class Clubs the following are declared protected   club  distance  cleanclub  scores  par  hole    which means these can only be accessed by the class itself or any class which derives from Clubs   In your main code  you try to access these outside of the class itself  eg   Console WriteLine  How far to the hole     myClub distance   Console ReadLine      You have  somewhat correctly  provided public accessors to these variables  eg   public string mydistance       get               return distance            set               distance   value                    which means your main code could be changed to   Console WriteLine  How far to the hole     myClub mydistance   Console ReadLine

User · Answer

Dan  it s just you re accessing the protected field instead of properties   See for example this line in your Main        myClub distance   Console ReadLine     myClub distance is the protected field  while you wanted to set the property mydistance   I m just giving you some hint  I m not going to correct your code  since this is homework

User · Answer

The reason being you can not access protected member data through the instance of the class   Reason why it is not allowed is explained in this blog

User · Answer

It s because you cannot access protected member data through its class instance  You should correct your code as follows   namespace homeworkchap8       class main                   static void Main string   args                            SteelClubs myClub   new SteelClubs                Console WriteLine  How far to the hole                 myClub mydistance   Console ReadLine                Console WriteLine  what club are you going to hit                 myClub myclub   Console ReadLine                myClub SwingClub                 SteelClubs mycleanclub   new SteelClubs                Console WriteLine   nDid you clean your club after                 mycleanclub mycleanclub   Console ReadLine                mycleanclub clean                 SteelClubs myScoreonHole   new SteelClubs                Console WriteLine   nWhat hole are you on                 myScoreonHole myhole   Console ReadLine                Console WriteLine  What did you score on the hole                 myScoreonHole myscore   Console ReadLine                Console WriteLine  What is the par of the hole                 myScoreonHole parhole   Console ReadLine                 myScoreonHole score                 Console ReadKey

User · Answer

myClub distance   Console ReadLine      should be  myClub mydistance   Console ReadLine       use your public properties that you have defined for others as well instead of the protected field members
