Solution 1

Try:

C#

var selected = studentsCollection.Where(s => s.ID == 3);

or

C#

Student justTheOne = studentsCollection.Where(s => s.ID == 3).FirstOrDefault();

You don't actually need a 'Where' statement at all, you can do this:
Student justTheOne = studentsCollection.FirstOrDefault(s => s.ID == 3);

Yeah - but he's a student and specifically mentioned Where, so it's probably part of the homework exercise.
