I need help with my code as I get an error every time it tries to output the student data.

The delete option won't work properly either, it won't display any of the existing data

What's the error and where does it happen? As a side note, writing

private int _foo = 0;
public int Foo {
    get { return _foo }
    set { _foo = value }
}

private int _foo = 0;
public int Foo {
    get { return _foo }
    set { _foo = value }
}

is just writing useless boilerplate code, it can be replaced by just

public int Foo { get; set; }

public int Foo { get; set; }

On this line case Student student: Console.WriteLine("{0,-10} {1,-15} {2,-10} {3,-15} {4,-20} {5,-10} {6,-8} {7,-8} {8,-5} {9,-10} {10,-10} {11,-15} {12,-15}", recordNumber++, student.Name, student.Role, student.Telephone, student.Email, "-", "-", "-", student.Subject, student.Subject2, student.PrvSubject, student.PrvSubject2); break; Thank you for the tip, I'll adjust my classes

You seem to have 13 slots in this string and 12 arguments That's why string interpolation is better
