通过继承无法在主类中使用方法 [英] Unable to a method in main class through inheritance

问题描述

您好我有继承的DisplayData方法，并且我成功地能够在继承的类中调用此方法。但不幸的是，我无法在主类中调用此方法，我已经创建了继承类的对象，并尝试访问未显示的DisplayData方法。我知道当你继承另一个类中的任何类时，你将能够访问所有方法和成员字段，但我无法做到..请澄清我。我的要求是我可以使用系统访问主类

Hi I have method DisplayData which is inherited and i am succefully able to call this method in inherited class. But unfortunately I am unable to call this method in main class i have created the object of for inherited class and tried accessing the DisplayData method its not shown. I am aware that when you inherit any class in another class you will be able to access all the methods and member fields but i am unable to do.. Please clarify me. My requirement is can i access the DisplayData() method in main class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

class student
{
    protected int _stdID;
    protected string _stringName;


    Protected void DisplayData()
    {

        Console.WriteLine("Name of the student {0} and id {1}", _stringName, _stdID);
    }

}
    class Csstudent : student
    {

        private int _sub1, _sub2;

        public Csstudent(int id, string name, int sub1, int sub2)
        {
            _stdID = id;
            _stringName = name;
            _sub1 = sub1;
            _sub2 = sub2;

        }


        public void StudentDetails()
        {
           //DisplayData();
            Console.WriteLine("Subject marks1 {0} and subject marks2 {1}",_sub1,_sub2);
        }
    }




    class Program 
{
    static void Main(string[] args)
    {


        Csstudent cs = new Csstudent(101, "Sha", 56, 96);

        cs.StudentDetails();
          

        
    }
}

推荐答案

引用：

我的要求是可以访问主类中的DisplayData（）方法

My requirement is can i access the DisplayData() method in main class

你实际可以，以下代码应该（并且在我的系统上）编译并运行正常。

You actually can, the following code should (and it does, on my system) compile and run fine.

static void Main(string[] args)
    {
 

        Csstudent cs = new Csstudent(101, "Sha", 56, 96);
 
        cs.StudentDetails();
        cs.DisplayData();
 
        
    }
