将 Array 转换为原始方法来表达相同的结果，不使用 LINQ，仅使用 int。

我的程序记录了四个房间在瓶子驱动器中收集的瓶子数量。当用户输入 quit 时，会显示每个房间收集的瓶子数量，并打印出拥有最多瓶子的房间。我使用了一个数组来跟踪房间号。如何更改方法而不是使用数组，我想启动 room1、room2、room3、room4。如果我不使用数组，我可以使用循环数组调用来写入行吗？我的意思是这些线条。

            int room = int.Parse(quit);
            Console.Write("Bottles collected in room {0}: ", room);
            // This line adds the count of bottles and records it so you can continuously count the bottles collected.
            rooms[room - 1] += int.Parse(Console.ReadLine());

还有这一行：

           }//Writes the bottles collected by the different rooms
            Console.WriteLine("Bottles collected in room {0} = {1}", i + 1, rooms[i]);

这是我的代码：

         namespace BottleDrive
   {
    class Program
   {
    static void Main(string[] args)
    {//Initialize array of rooms to 4
        int[] rooms = new int[4];
        //Start of while loop to ask what room your adding into. 
        while (true)
        {
            Console.Write("Enter the room you're in: ");
            //If user enters quit at anytime, the code will jump out of while statement and enter for loop below
            string quit = Console.ReadLine();
            if (quit == "quit")
                //Break statement allows quit to jump out of loop
                break; 


           //Variable room holds the number of bottles collect by each room. 
            int room = int.Parse(quit);
            Console.Write("Bottles collected in room {0}: ", room);
            // This line adds the count of bottles and records it so you can continuously count the bottles collected.
            rooms[room - 1] += int.Parse(Console.ReadLine());

        }

        int maxValue = 0;//initiates the winner, contructor starts at 0
        int maxRoomNumber = 0;//initiates the room number that wins
        for (int i = 0; i < rooms.Length; ++i)//This loop goes through the array of rooms (4)
        {
            if (rooms[i] > maxValue)//Makes sure that the maxValue is picked in the array
            {//Looking for room number for the 
                maxValue = rooms[i];
                maxRoomNumber = i + 1;
            }//Writes the bottles collected by the different rooms
            Console.WriteLine("Bottles collected in room {0} = {1}", i + 1, rooms[i]);
        }
        //Outputs winner
        Console.WriteLine("And the Winner is room " + maxRoomNumber + "!!!");

    }
}
 }

谢谢你，我很感激这个社区对我学习 c Sharp 的帮助。

您无法轻松地将数组替换为单个变量。如果您有类似的声明

int room1 = 0, room2 = 0, room3 = 0, room4 = 0;

并想要访问房间号i那么你必须写

switch (i) {
    case 1:
        Console.WriteLine(room1);
        break;
    case 2:
        Console.WriteLine(room2);
        break;
    case 3:
        Console.WriteLine(room3);
        break;
    case 4:
        Console.WriteLine(room4);
        break;
}

使用数组你可以简单地写

Console.WriteLine(rooms[i]);

如果你真的想采用这种无数组的方式，我建议你使用辅助方法：

private void SetRoom(int room, int value)
{
    switch (room) {
        case 1:
            room1 = value;
            break;
        case 2:
            room2 = value;
            break;
        case 3:
            room3 = value;
            break;
        case 4:
            room4 = value;
            break;
    }
}

public int GetRoom(int room)
{
    switch (room) {
        case 1:
            return room1;
        case 2:
            return room2;
        case 3:
            return room3;
        case 4:
            return room4;
        default:
            return 0;
    }
}

您必须将变量 room1 到 room4 声明为类成员才能完成此操作。

现在你可以写：

Console.WriteLine(GetRoom(i));

或者代替rooms[i] += n;

SetRoom(i, GetRoom(i) + n);
