Question

我正在尝试将随机座位代码链接到我的用户界面类，我很难理解如何通过我的用户界面随时调用它。以下内容目前保留在{ Random rand = new Random(); bool[] seats = new bool[32]; //To keep a separate list of seats taken List<int> seatsBooked = new List<int>(); bool quit = false; do { Console.Clear(); //int seatAssignFirstClass = rand.Next(0, 32);-> Moved to switch-case 1: block int seatAssignThirdClass = rand.Next(32); int seatAssignFirstClass; //Variable moved from main loop //Are there any seats booked already or this is the first? if (seatsBooked.Count == 0) //if this is the first seat to be booked... { seatAssignFirstClass = rand.Next(0, 32); seats[seatAssignFirstClass] = true; seatsBooked.Add(seatAssignFirstClass); //Add seat to the list of booked seats. } else { do //while there are available seats and current seat has not being assigned before. { seatAssignFirstClass = rand.Next(0, 32); if (!seatsBooked.Contains(seatAssignFirstClass)) //if seatAssignFirstClass is not booked. { seats[seatAssignFirstClass] = true; } //repeat while the random seat number is already booked and there are avaialable seats } while (seatsBooked.Contains(seatAssignFirstClass) && seatsBooked.Count < 32); //IMPORTANT: Number on line bellow needs tos be one bigger than rest if (seatsBooked.Count < 34) //if seatsBooked list is not full for First Class { seatsBooked.Add(seatAssignFirstClass); //Add current random-generated seat to the list. } } //IMPORTANT: Number on line bellow needs tos be one bigger than rest if (seatsBooked.Count >= 34) //If all seats are booked { Console.WriteLine("All seats for First Class are booked"); Console.WriteLine("Press enter to continue..."); } else //Give customer their seat nmumber { Console.WriteLine("Train seat number: {0}", seatAssignFirstClass + 1); Console.WriteLine("Press enter to continue to the main menu..."); } } while (!quit);级别内。

Answer 1

C＃中最小的代码重用单元是一个函数。您需要将此代码放在一个函数中，然后您可以从其他地方调用它。最容易成为public static函数，但随着您对设计的了解越多，您可能会发现有更好的方法来共享功能。

Answer 2

您可以使用using关键字和所需的类＆＃39;添加对其他文件中的类的引用。 namespace

示例：

namespace MyProject.MyCore {
    public class MyClass {
        public void MyMethod() { }
    }
}

然后，您将在调用类中引用此命名空间，如下所示：

using MyProject.MyCore

允许您实例化类对象，如下所示：

var myInstantiatedClass = new MyClass();

并称之为：

myInstantiatedClass.MyMethod();

方法也可以标记为静态，这样就无需实例化类，而是使用Type.Method（）语法调用，例如MyClass.MyMethod()。

您还可以使用完全限定的路径放弃添加引用。

var myInstantiatedClass = new MyProject.MyCore.MyClass()

当然，如果此代码位于不同的项目或程序集中，您必须添加对项目或二进制文件的引用以访问它提供的类型。

Answer 3

This example may be your answer

或者你可以使用像

这样的静态方法

np.asarray([np.asarray(a[0]), np.asarray(a[1])]) / 10.

你可以从另一个类

中使用这个方法

namespace MyProject.MyCore {
    public class MyClass {
        public static void MyMethod() { }
    }
}

如何在另一个C＃中使用一个类的代码
