问题描述

link没有运行结果，请问哪里编写错误？

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

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string[] courses = { ""体育课""体育课""美术课""音乐课""劳动课""语文课""语文课""语文课""语文课""语文课""语文课""语文课""
数学课""数学课""数学课""数学课""数学课""数学课""数学课""英语课""英语课""英语课""英语课""英语课""
英语课""英语课""};
var result = Enumerable.Range(0 5).Select(_ => Enumerable.Range(0 6).Select(__ => """").ToArray()).ToArray();
var rndseq = Enumerable.Range(0 30).OrderBy(_ => Guid.NewGuid()).Zip(courses (x y) => new { x y }).ToArray();
while (true && !result.All(x => x.Contains(""语文课"") && x.Contains(""数学课"") && x.Contains(""英语课"")))
{
for (int i = 0; i < 5; i++)
{
for (int j = 0; j < 6; j++)
{
if (rndseq.Any(x => x.x == i * 6 + j))
result[i][j] = rndseq.First(x => x.x == i * 6 + j).y;
else
result[i][j] = ""自修课"";
}
}
}
for (int j = 0; j < 6; j++)
{
for (int i = 0; i < 5; i++)
{
Console.Write(result[i][j] + ""t"");
}
Console.WriteLine();
}
}
}
}

解决方案

while (true &&
不好意思，这里忘记去掉true了，陷入死循环了。

解决方案二：

 using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Text.RegularExpressions;using System.Threading.Tasks;namespace ConsoleApplication1{    class Program    {        static void Main(string[] args)        {            string[] courses = { ""体育课""体育课""美术课""音乐课""劳动课""语文课""数学课""英语课""};            var result = Enumerable.Range(0 5).Select(_ => Enumerable.Range(0 6).Select(__ => """").ToArray()).ToArray();            while (!result.All(x => x.Contains(""语文课"") && x.Contains(""数学课"") && x.Contains(""英语课"")))            {                var rndseq = Enumerable.Range(0 30).OrderBy(_ => Guid.NewGuid()).Zip(courses (x y) => new { x y }).ToArray();                for (int i = 0; i < 5; i++)                {                    int pos = 0;                    string[] cs = { ""语文课""数学课""英语课"" };                    for (int j = 0; j < 6; j++)                    {                        if (rndseq.Any(x => x.x == i * 6 + j))                            result[i][j] = rndseq.First(x => x.x == i * 6 + j).y;                        else                            result[i][j] = (pos++ < 3) ? cs[pos - 1] : ""自修课"";                    }                }            }            result = result.Select(x => x.OrderBy(_ => Guid.NewGuid()).ToArray()).ToArray();            for (int j = 0; j < 6; j++)            {                for (int i = 0; i < 5; i++)                {                    Console.Write(result[i][j] + ""t"");                }                Console.WriteLine();            }        }    }}

这样应该好了
