Question

I have class grades that I need to check if a specific grade is pass or fail. This is the list of grades in order:

1. A
2. A-
3. B+
4. B
5. B-

If B is the pass mark, and The student has B+, using the normal ordering, if I check if the studentGrade > passMark, then its going to say it is failed because the system orders the strings as follows:

1. A
2. A-
3. B
4. B+
5. B-

How do I setup a custom comparer for ordering a list as the first list in c#?

Answer 1

How about setting up your letter grades by numeric value?

• A = 4.0
• A- = 3.7
• B+ = 3.3
• B = 3.0

and so on….

Then order by numeric value rather than letter grade. 3.0 can be the pass mark.

Just a thought.
