名称''在当前上下文中不存在

CRN courseid timedays Roomnumber

在显示屏上，没有任何项目被识别。为什么显示器在声明为set并获得时没有看到它们？

using System.Text;


   public class Section
{

       private int crn;
       private String courseId;
       private String timeDays;
       private String roomNumber;
       private int instructor;

    public void display(){
        System.Console.WriteLine("CRN =  "+ getCrn());
        System.Console.WriteLine("CourseID =   "+ getCourseId());
        System.Console.WriteLine("Time Days =  " + getTimeDays());
        System.Console.WriteLine("Room Number =  " + getRoomNumber());

    }



    }

我认为display（）需要如下所示。我不知道你的display（）函数是如何编译的。

public void display()
{
    System.Console.WriteLine("CRN =  "+ Crn);
    System.Console.WriteLine("CourseID =   "+ CourseId);
    System.Console.WriteLine("Time Days =  " + TimeDays);
    System.Console.WriteLine("Room Number =  " + RoomNmber);

}

此外，由于您使用{get;声明了所有属性组; }，您不需要任何后备成员变量（编译器会自动为您处理这些变量）。因此，您可以删除如下所示的行：

private int crn;
private String courseId;
private String timeDays;
private String roomNumber;
private int instructor;

当前上下文中不存在显示名称
