无法访问由于其保护级别 [英] is inaccessible due to its protection level

问题描述

帮助我，我不能想出解决办法。问题是，距离，俱乐部，cleanclub，洞，成绩，和参数都因保护级别人迹罕至的说，我不知道为什么，因为我认为我做的一切权利。

 命名空间homeworkchap8 
 {
公共类俱乐部
 {
保护串俱乐部; 
保护串的距离; 
保护串cleanclub; 
保护串分数; 
保护串相提并论; 
保护的弦孔; 
 
公共字符串Myclub上海
 {
得到
 {
返回俱乐部; 
} 
组
 {
俱乐部=价值; 
} 
} 
公共字符串mydistance 
 {
得到
 {
返回的距离; 
} 
组
 {
距离=价值; 
} 
} 
公共字符串mycleanclub 
 {
得到
 {
返回cleanclub; 
} 
组
 {
 cleanclub =价值; 
} 
} 
公共字符串myScore的
 {
得到
 {
回报率的分数; 
} 
组
 {
分数=价值; 
} 
} 
公共字符串parhole 
 {
得到
 {
返回面值; 
} 
组
 {
 =票面价值; 
} 
} 
公共字符串myhole 
 {
得到
 {
返回孔; 
} 
组
 {
孔=价值; 
} 
} 
} 
} 
  

这是派生类：

 命名空间homeworkchap8 
 {
公共类SteelClubs：俱乐部，ISwingClub 
 {
公共无效SwingClub（）
 {
 Console.WriteLine（你打一个+ Myclub上海++ mydistance）; 
} 
 
公共无效干净（）
 {
如果（mycleanclub！=是）
 {
 Console.WriteLine（你的俱乐部脏）; 
} 
，否则
 {
 Console.WriteLine（你的俱乐部是干净的）; 
} 
} 
 
公共无效得分（）
 {
 Console.WriteLine（你是在孔+ myhole +，你打进了+ 
 myScore的+相提并论+ parhole）; 
} 
} 
} 
  

这是界面：

 命名空间homeworkchap8 
 {
公共接口ISwingClub 
 {
无效SwingClub（） ; 
无效干净（）; 
无效得分（）; 
} 
} 
  

下面是主要代码：

 命名空间homeworkchap8 
 {
类主要
 {
静态无效的主要（字串[] args） 
 {
 SteelClubs Myclub上海=新SteelClubs（）; 
 Console.WriteLine（有多远洞口？）; 
 myClub.distance =到Console.ReadLine（）; 
 Console.WriteLine（你打算什么俱乐部打？）; 
 myClub.club =到Console.ReadLine（）; 
 myClub.SwingClub（）; 
 
 SteelClubs mycleanclub =新SteelClubs（）; 
 Console.WriteLine（\\\
Did你清理后你的俱乐部？）; 
 mycleanclub.cleanclub =到Console.ReadLine（）; 
 mycleanclub.clean（）; 
 
 SteelClubs myScoreonHole =新SteelClubs（）; 
 Console.WriteLine（\\\
What孔是你吗？）; 
 myScoreonHole.hole =到Console.ReadLine（）; 
 Console.WriteLine（你是怎么在比分上洞？）; 
 myScoreonHole.scores =到Console.ReadLine（）; 
 Console.WriteLine（什么是洞的标准杆？）; 
 myScoreonHole.par =到Console.ReadLine（）; 
 
 myScoreonHole.score（）; 
 
 Console.ReadKey（）; 
} 
} 
} 
  

解决方案

在你的基类俱乐部以下是声明保护

• 俱乐部;


• 的距离;


• cleanclub;


• 分数;


• 参数;


• 孔;

这意味着，这些只能由类本身或从俱乐部派生的任何类访问。

在你的主代码，您试图访问这些类本身之外。例如：

  Console.WriteLine（？多远洞）; 
 myClub.distance =到Console.ReadLine（）; 
  

您已经（有点正确）提供的公共访问到这些变量。例如：

 公共字符串mydistance 
 {
得到
 {
返回的距离; 
} 
组
 {
距离=价值; 
} 
} 
  

这意味着你的主代码可以改为

  Console.WriteLine（有多远洞口？）; 
 myClub.mydistance =到Console.ReadLine（）; 
  

help me i cant figure this out. The problem is that the distance, club, cleanclub, hole , scores , and par all say inaccessible due to protection level and I don't know why because I thought I did everything right.

namespace homeworkchap8
{
    public class Clubs
    {
        protected string club;
        protected string distance;
        protected string cleanclub;
        protected string scores;
        protected string par;
        protected string hole;            

        public string myclub
        {
            get
            {
                return club;
            }
            set
            {
                club = value;
            }
        }        
        public string mydistance
        {
            get
            {
                return distance;
            }
            set
            {
                distance = value;
            }
        }        
        public string mycleanclub
        {
            get
            {
                return cleanclub;
            }
            set
            {
                cleanclub = value;
            }
        }       
        public string myscore
        {
            get
            {
                return scores;
            }
            set
            {
                scores = value;
            }
        }       
        public string parhole
        {
            get
            {
                return par;
            }
            set
            {
                par = value;
            }
        }       
        public string myhole
        {
            get
            {
                return hole;
            }
            set
            {
                hole = value;
            }
        }
    }   
}

this is the derived class:

namespace homeworkchap8
{
    public class SteelClubs : Clubs, ISwingClub
    {
        public void SwingClub()
        {
            Console.WriteLine("You hit a " + myclub + " " + mydistance);
        }

        public void clean()
        {
            if (mycleanclub != "yes")
            {
                Console.WriteLine("your club is dirty");
            }
            else
            {
                Console.WriteLine("your club is clean");
            }
        }

        public void score()
        {   
            Console.WriteLine("you are on hole " + myhole + " and you scored a " + 
                myscore + " on a par " + parhole);
        }            
    }
}

This is the interface:

namespace homeworkchap8
{
    public interface ISwingClub
    {
        void SwingClub();
        void clean();
        void score();
    }  
}

here is the main code:

namespace homeworkchap8
{
    class main
    {    
        static void Main(string[] args)
        {    
            SteelClubs myClub = new SteelClubs();
            Console.WriteLine("How far to the hole?");
            myClub.distance = Console.ReadLine();
            Console.WriteLine("what club are you going to hit?");
            myClub.club = Console.ReadLine();
            myClub.SwingClub();

            SteelClubs mycleanclub = new SteelClubs();
            Console.WriteLine("\nDid you clean your club after?");
            mycleanclub.cleanclub = Console.ReadLine();
            mycleanclub.clean();

            SteelClubs myScoreonHole = new SteelClubs();
            Console.WriteLine("\nWhat hole are you on?");
            myScoreonHole.hole = Console.ReadLine();
            Console.WriteLine("What did you score on the hole?");
            myScoreonHole.scores = Console.ReadLine();
            Console.WriteLine("What is the par of the hole?");
            myScoreonHole.par = Console.ReadLine();

            myScoreonHole.score();

            Console.ReadKey();    
        }
    }
}

解决方案

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();
