link制作课程表，要求避免早上第一节课是体育课，怎么修改？

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"" };
string[] xinqi = { ""一""二""三""四""五"" };
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"") && x.Contains(""自修课"")))
{
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 i) => new string[] { ""星期"" + xinqi[i] }.Concat(x.OrderBy(y => y == ""自修课"" ? 1 : 0).ThenBy(_ => Guid.NewGuid()).GroupBy(y => y).SelectMany(y => y)).ToArray()).ToArray();
for (int j = 0; j < 7; j++)
{
for (int i = 0; i < 5; i++)
{
Console.Write(result[i][j] + ""t"");
}
Console.WriteLine();
}
}
}
}

解决方案

while (!result.All(x => x.Contains(""语文课"") && x.Contains(""数学课"") && x.Contains(""英语课"") && x.Contains(""自修课"") && x[0] != ""体育课""))
