❔ Foreach loop

I am trying to run through my list, but nothing is being printed out, what am I doing wrong?

            List<Enrollment> tilmeldingslist = new List<Enrollment>();
            Enrollment enroll1 = new Enrollment(Alex, Programmering);
            Enrollment enroll2 = new Enrollment(Alex, Matematik);
            Enrollment enroll3 = new Enrollment(Alex, Dansk);

            foreach (var items in tilmeldingslist)
            {
                Console.WriteLine(items);
            }

            List<Enrollment> tilmeldingslist = new List<Enrollment>();
            Enrollment enroll1 = new Enrollment(Alex, Programmering);
            Enrollment enroll2 = new Enrollment(Alex, Matematik);
            Enrollment enroll3 = new Enrollment(Alex, Dansk);

            foreach (var items in tilmeldingslist)
            {
                Console.WriteLine(items);
            }

Does enrollment class has a ToString() method?

DayKnight•2y ago

No I am not sure why it isn't printing anything, because it should have values inside the list right?

WhiteBlackGoose•2y ago

did you add elements to the list?

If you want to print the name and the enrollment class you should have a ToString() method on the class and format there your message

you didn't add anything to the list you just made the Enrollments without adding them

Oooh... A website suggests that I do this, but is this really what I am looking for?

authors.Add(new Author { Name = "Mahesh Chand", Book = "Graphics with GDI+", Price = 49.95 });

authors.Add(new Author { Name = "Mahesh Chand", Book = "Graphics with GDI+", Price = 49.95 });

Should I use .Add?

Aaron•2y ago

.Add does add things to the list, yes

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
