we are NOT using MVC in this project. Populating the IEnum like this;

public IEnumerable<CompanyList> CompanyListe() {

        var connectionString = "foobar";


        using (SqlConnection connection = new SqlConnection(connectionString))
        {

            var command = "SELECT COMPANY_ID , COMPANY_ID FROM TUSER";

           return connection.Query<CompanyList>(command);

        }


            }

 public class CompanyList {

            public int COMPANY_ID { get; set; }

            public string COMPANY_NAME { get; set; }

        }

As a result, we have the data we request but don't know how to populate that without MVC, into a select list. Can you help?
