Fill List in an array through a class contructor

Question

I need to create a program where the user can fill in 4 names with 1 programming specialty.
I created 2 classes and a separate enum file.
I can't get the List<Programmeur> programmeurs = new List<Programmeur>(); get to start an instance with the Programmer class contructor so that 4 names are asked and being printed.

I hope someone can give me some solution or help so i can understand it. I included the files in a rar. Thx.
