我的程序收集了四个房间收集的瓶子数量。当用户随时键入退出时,程序会不时显示并显示瓶子收集的结果。然后计算具有最多瓶数的获胜房间。
我有一个while循环我不明白为什么我不能输入它。要进入while循环,它会提示我输入数组中使用的数字1-4,以及每个房间收集的瓶数。如果我在任何时候输入退出,该程序将停止记录瓶子并吐出结果和最多瓶子的获胜房间。
如何输入“输入您所在的房间号码”,在我输入瓶数之前先显示?我的问题存在于getBottles()
中我认为这条线不能用在数组中,我是对的吗?
rooms [room - 1] + = int.Parse(Console.ReadLine());
namespace BottleDrive
{
class BottleDrive
{
public int[] rooms;
public BottleDrive()
{
rooms = new int[4];
}
static void Main(string[] args) //static is member of class not object
{
BottleDrive bD = new BottleDrive();
bD.getBottles();
bD.displayBottleCount();
bD.findWinner();
}
public void getBottles()
{
string quit = Console.ReadLine();
while while(quit != "quit")
{
int room = int.Parse(quit);
Console.Write("Bottles collected in room {0}: ", room);
rooms[room - 1] += int.Parse(Console.ReadLine());
Console.Write("Enter the room you're in: ");
}
}
public void findWinner()
{
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;
}
}
Console.WriteLine("And the Winner is room " + maxRoomNumber + "!!!");
}
public void displayBottleCount()
{
Console.WriteLine("Bottles collected in room one: " + rooms[0]);
Console.WriteLine("Bottles collected in room two: " + rooms[1]);
Console.WriteLine("Bottles collected in room three: " + rooms[2]);
Console.WriteLine("Bottles collected in room four: " + rooms[3]);
}
}
}

while (quit == "quit")
如果退出(从控制台获得的内容)是“退出”,上面的行只会运行循环。
你想:
while (quit != "quit")
或
while (!quit.Equals("quit"))
毕竟,虽然你实际上并没有在你的循环中更新quit,所以一旦进入你就永远不会离开。
您需要捕获您的console.Readline并将其放入“退出”。
如果用户输入的字符串不是退出或有效整数,您可能还需要查看int.TryParse。 TryParse会告诉你解析是否成功,而不是抛出异常。

这一行:
while (quit == "quit")
实际应该是:
while (quit != "quit")
或者更好:
while (!quit.Equals("quit", StringComparison.CurrentCultureIgnoreCase))
这将忽略输入的大小写。正如其他人所说,你的循环存在更多问题。尝试将此用于getBottles函数:
public void getBottles()
{
string input;
do
{
Console.Write("Enter the room you're in: (or quit)");
input = Console.ReadLine();
int room;
// doing try parst because the input might be "quit" or other junk
if (int.TryParse(input, out room))
{
Console.Write("Bottles collected in room {0}: ", room);
// this will fail hard if the input is not of type int
rooms[room - 1] += int.Parse(Console.ReadLine());
}
} while (!input.Equals("quit", StringComparison.CurrentCultureIgnoreCase));
}

你是否应该为{while}条件while(quit != "quit")
?
答案 3 :(得分:0)
尝试:
while (!quit.Equals("quit"))
答案 4 :(得分:0)
函数getBottles()看起来很奇怪。键入“quit”时只输入while循环。我认为这不是你想要的行为。
