While I also prefer the LINQ solution, you could alternatively make your Student class implement IComparable, which could give you more complex sorting options without having to write an in-line function every time.

You could use something like this:

Array.Sort(array, (s1, s2) => s1.Name.CompareTo(s2.Name));

You can define the comparator function however you want to get different sorting orders.

If it’s an array, the most efficient way is to use Array.Sort:

Array.Sort(array, (s1, s2) => s1.Name.CompareTo(s2.Name));

you can use linq:

sortedStudents1 = students.OrderBy(s=>s.Name).ToList();
sortedStudents2 = students.OrderBy(s=>s.ID).ToList();

I would use a list for this.

List<Student> students = new List<Student>{ new Student(), new Student(), new Student() }

then sort that list with LINQ

var sortedStuds = students.OrderBy(s => s.ID).ToList();

where the s is a Student object
