Question

我正在尝试制作一个Secret Santa代码，以便在运行该程序时，它将从数组中获取所有名称并将它们配对。

我已经尝试了多种方法来执行此操作，但是最终只是在输出中重复了一个条目。例如：

弗雷德和莎拉

Yusef和Kyle

萨拉和弗雷德

萨拉（Sarah）来了两次，这不好。这是开始代码，我当然首先将数组随机化，但是不知道在那之后该怎么做。

int main() {
    int i = 0, j, n = 10;

    loop:
    for (j = 0; j <= n; j++) {
        putchar(j++ >= n - 1 ? '#' : ' ');
    }

    puts("");
    if (i++ < n) goto loop;

    return 0;
}

任何想法，任何人都可以帮忙吗？

我也尝试过这种方法，我认为这可以解决问题，但是它返回索引超出数组范围的错误

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp27
{
class Program
{
    static void Main(string[] args)
    {
        Random random = new Random();
        String[] students = {"Fred","Mary","Yusef","Kyle","Sophie", "Lydia", "Max", "Donald","Yasmin","Archie"};
        string[] shuffleStudents = students.OrderBy(x => random.Next()).ToArray();



    }
}
}

}

Answer 1

您可以尝试将它们洗牌，然后打印结果。这是我做的代码：

using System;
using System.Linq;

namespace _05_01_19_5am
{
    class Program
    {
        public static void Main()
        {
            Random random = new Random();
            String[] students = { "Fred", "Mary", "Yusef", "Kyle", "Sophie", "Lydia", "Max", "Donald", "Yasmin", "Archie" };

            var shuffleThem = students.OrderBy(s => Guid.NewGuid()).ToArray();

            for (int i = 0; i < 5; i++)
            {
            Console.WriteLine(shuffleThem[i] + " + " + shuffleThem[i+5]);
            }
        }
    }
}

Answer 2

摆弄一些东西，找到了解决方法。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp27
{
class Program
{
    static void Main(string[] args)
    {
        Random random = new Random();
        string[] students = { "Fred", "Mary", "Yusef", "Kyle", "Sophie", "Lydia", "Max", "Donald", "Yasmin", "Archie"};
        string[] shuffleStudents = students.OrderBy(x => random.Next()).ToArray();

        Console.WriteLine("Your pairs for Secret Santa has been completed!");

        int count = 0;

            for (int j = 0; j < 5; j++)
            {

                Console.Write("{0} and {1} \n", shuffleStudents[count], shuffleStudents[count+1]);
            for (int i = 0; i < 2; i++)
            {
                count++;

            }
        }


        Console.Read();

    }
}

}

如何在不重复自身的情况下配对此数组的内容？
