C# C语言中的石头、布、剪刀#

我正在用C#制作一个石头、布、剪刀游戏，当有人输入一个不是R、S或p的输入时，我现在很难显示消息。例如，我试图让switch语句中的默认值起作用，但运气不好。这就是我现在拥有的。如果我还有其他问题，请告诉我

请帮忙

虽然这不能直接回答您的问题，但它应该显示请求用户输入的程序的逻辑/流程，并再次询问他们是否输入了无效输入

            while (true)
            {
                Console.WriteLine("1. Print A then C");
                Console.WriteLine("2. Print B then C");
                Console.Write("Enter option: ");

                var input = Console.ReadLine();
                switch (input)
                {
                    case "1":
                        Console.WriteLine("A");
                        break;
                    case "2":
                        Console.WriteLine("B");
                        break;
                    default:
                        Console.WriteLine("Invalid Input. Please try again");
                        continue;
                }

                Console.WriteLine("C");
            }

在这里，打印A/B就像选择你的手，而打印C就像显示结果。

default

分支使用

continue

（）返回循环的开头，因此不打印C

---

我建议在如下数组中声明您的有效移动：

string[] validMoves = new string[3] { "R", "P", "S" };

string playerInput = GetStringFromUser(
    "To play: enter R for Rock, S for Scissors, P for Paper: ",
    x => x.ToUpper() == "R" || x.ToUpper() == "S" || x.ToUpper() == "P");

Console.WriteLine($"You entered: {playerInput}");

Console.Write("\nPress any key to continue...");
Console.ReadKey();

然后，在switch语句匹配之前，如果用户提供的输入有效或无效，则重新运行

while

循环，否则，继续执行

switch

语句。如下所示：

if (!validMoves.Contains(inputPlayer))
{
    Console.WriteLine("Please select a valid move.");
    continue;
}

以下是您的主要方法的外观：

    int wins = 0;
    int Loses = 0;
    int ties = 0;
    while (keepPlaying)
    {
      // while (keepPlaying) // You can get rid of this while loop as it is not helping you out.
      // { // second while loop opening
            Random myRandomObject = new Random();
            randomnum = myRandomObject.Next(1, 4);
            Console.Write("To play: enter R for Rock, S for Scissors, P for Paper.");
            inputPlayer = Console.ReadLine();
            inputPlayer = inputPlayer.ToUpper();

            if (!validMoves.Contains(inputPlayer))
            {
                Console.WriteLine("Please select a valid move.");
                continue;
            }

            switch (randomnum)
            {

下面是我在控制台应用程序中使用的一种方法，它非常有用。实际上，我有几个用于从用户那里获取类型（如

int

或

double

）。它接收一个提示，向用户显示该提示，并包含一个可选的验证器方法，它将对输入运行该方法，以查看其是否有效

这里有一个字符串输入：

public static string GetStringFromUser(string prompt, Func<string, bool> validator = null)
{
    var isValid = true;
    string result;

    do
    {
        if (!isValid)
        {
            WriteLineColor("Invalid input, please try again.", ConsoleColor.Red);
        }
        else isValid = false;

        Console.Write(prompt);
        result = Console.ReadLine();
    } while (validator != null && !validator.Invoke(result));

    return result;
}

下面是示例输出：

这是我对RPS游戏以及如何处理用户输入的看法。在设计方面，我定义了一些

enum

类型来描述不同的动作或结果

public enum Move
{
    Rock,
    Scissors,
    Paper,
}

public enum Outcome
{
    Tie,
    Loss,
    Win,
}

然后我有两个助手函数，一个用于处理用户输入（op遇到问题的部分），另一个用于决定游戏，因为op的重复让我头疼

本着C#函数的精神，例如

int.TryParse（string，out int）

我设计了

PlayerMove（）

函数，如果成功，它将返回

true

，否则返回

fase

。函数的实际结果分配给名为

move

的

out

变量

switch语句没有直接处理用户输入，因此不清楚默认情况与此有何关系。只有当开关进入其他情况之一时，才会检查用户输入。如果它这样做了，那么它就不会进入默认状态。在这些不同的情况下，您有很多重复的代码。您学习并能够使用了吗？而且您似乎有两个while循环检查同一个变量，但不确定这是关于什么的。看看我对这个问题的回答：。它不是一个控制台应用程序，但逻辑应该是SamemyRandoObject。下一步（1，4）将只返回1，2或3。所以不符合默认情况。回答不错。注意：现在，您可以跳过

null

检查，只需执行

！validator？.Invoke（result）

@3Dave几乎可以，除了它必须求值为

bool

，而不是

bool？

，因此您必须执行类似

（！validator？.Invoke（result）？false）

，这样读起来就有点困难。
