根据总分排序
学生成绩包括chinese math english physic history
一个人五门成绩
姓名，成绩1 ，成绩2，等（txt文件）
输出txt文件是
姓名，成绩1 ，成绩2，等，总分

using (StreamWriter writer = new StreamWriter("sorted_students.txt"))

foreach (Student student in students.OrderByDescending(s => s.TotalScore))
{
writer.WriteLine($"{student.Name},{student.Chinese},{student.Math},{student.English},{student.Physics},{student.History},{student.TotalScore}");
}
}
Student highest = students.OrderByDescending(s => s.TotalScore).First();
Console.WriteLine($"最高分：{highest.Name} {highest.TotalScore}");
Student lowest = students.OrderBy(s => s.TotalScore).First();
Console.WriteLine($"最低分：{lowest.Name} {lowest.TotalScore}");
}
}
在这段代码中，我们首先读取学生信息并将其存储在列表中。然后，我们将这些学生按照总分从高到低排序，并将结果写入新文本文件。最后，我们找到了最高分和最低分的学生，并在控制台中输出他们的信息。
希望能帮助到您，答案仅供参考
定义两个类来实现，一个Student用于表示学生及各科成绩，一个MainClass用来读取文件、转换成Student对象、排序、输出等。
望采纳，谢谢！

使用linq. 直接orderby
