How to shorten my objects by using SelectMany?

Question

I have class Contact:

 public class Contact
    {
    public string Function { get; set; };

    public string Civility { get; set; }

    public string FirstName { get; set; }


    public List<Certification> Certifications { get; set; } = new List<Certification>();

}

My query logic is as follows:

List<Contact> contacts
                  = await Context.Database
                                         .SqlQuery<Contact>("[dbo].[Contact] @codes,@Sprache",
                                         parameters).ToListAsync();

How to use .selectMany fot have olny names of functions of this class?

Answer 1

If you want distinct objects why not use Distinct() . From my understand Select Many will flatten (aka reduce the nested collections) a collection. Check this question out
