如何在Linq中订购组结果？

var orderedStudents = students.OrderBy(student => student.Score);

var orderedStudents = students.OrderByDescending(student => student.Score);

var groupedStudents = students.GroupBy(student => student.Score)
                               .OrderBy(group => group.Key);

var groupedStudents = students.GroupBy(student => student.Score)
                               .OrderByDescending(group => group.Key);

var orderedStudents = students.OrderBy(student => student.Score)
                               .ThenBy(student => student.Name);

var orderedStudents = students.OrderByDescending(student => student.Score)
                               .ThenByDescending(student => student.Name);
