Are you trying to build a List of Customers?

var customers = new List<Customer>()

    new Customer() { Id = 0, Name = "Dave", City = "Sarasota" },

};

var customers = new[]
{
    new { Id = 0, Name = "Dave", City = "Sarasota" },
    new { Id = 1, Name = "Ed", City = "London" },

foreach (var customer in customers)

You have the ref keyword but it only works on value types

namespace RefChecker

    class Program
    {
        static void changeMyString1(string myString)
        {
            myString += " worked";

        static void changeMyString2(ref string myString)

            myString += " worked";

        static void Main(string[] args)

            string string1 = "has it";
            string string2 = "has it";

            changeMyString1(string1);
            changeMyString2(ref string2);

            Console.WriteLine(string1);//outputs has it
            Console.WriteLine(string2);//outputs has it worked

        }
