记录每个客户的系统列表和汽车列表

Question

我正在对机械记录系统进行简单的模拟，其中将包含客户列表及其详细信息；每个人都有自己拥有的汽车清单。每次访问也会被记录。

客户：姓名、地址、汽车清单（包括品牌、型号和注册号）

访问：日期、所有者、汽车、完成工作的描述、下次访问日期

在主要方法中，我需要模拟两个客户端的创建，每个客户端有 5 辆汽车。数据将被硬编码。然后需要添加7次访问并显示所有信息。

class Human 
{

    int id;

    public int Id
    {
        get { return id; }
        set { id = value; }
    }

    private string name;

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private string address;

    public string Address
    {
        get { return address; }
        set { address = value; }
    }
}

class Customer : Human
{
    public LinkedList<Car> Cars = new LinkedList<Car>();

   public Customer()
   {

   }


 }

 public class Visit
{


    public int visitId { get; set; }
    public DateTime DateTimeVisited { get; set; }
    public string customer { get; set; }
    public string Discussion { get; set; }

    public DateTime NextDateTimetoVisit { get; set; }

}

 class Mechanic :Human
{

    public LinkedList<Customer> customerDetails;

    public LinkedList<Visit> visitDetails;

    public LinkedList<Car> carDetails;

    public Mechanic()
    {
        customerDetails = new LinkedList<Customer>();

        visitDetails = new LinkedList<Visit>();

        carDetails = new LinkedList<Car>();

    }

    public void AddCustomer(Customer c)
    {

        customerDetails.AddLast(c);
    }

    public void AddVisit(Visit v)
    {

        visitDetails.AddLast(v);
    }



    public LinkedList<Customer> ViewCustomer()
    {

          return customerDetails;
    }

     public LinkedList<Visit> ViewVisit()
    {

        return visitDetails;
    }


     public void AddCar(Car car)
     {

         carDetails.AddLast(car);
     }


}

                    mech1.AddCustomer(customer1);

                    Car car1 = new Car();

                    car10.Id = 2;
                    mech1.AddCar(car10);

当我调试汽车是否属于特定客户时，它们似乎是单独声明的，客户没有汽车。访问类也正确实现了吗？我哪里错了？谢谢

Answer 1

像这样将所有列表以及 AddCar 方法移动到基类中：

class Human 
{
 public LinkedList<Customer> customerDetails;

 public LinkedList<Visit> visitDetails;

 public LinkedList<Car> carDetails;

 public void AddCar(Car car)
 {

     carDetails.AddLast(car);
 }
 ...
}

class Customer:public Human
{
 ...
}
