Can't pickup all dates between two datetimepicker C# Win Forms

Question

Have a problem with my soft... There is two datetimepickers in my app, i should make a list of dates between selected dates in my app. Also, i need to add them to Access datebase.

        DateTime start = new DateTime();
        start = dateTimePicker1.Value;
        DateTime end = new DateTime();
        end = dateTimePicker2.Value;


        Enumerable.Range(0, 1 + end.Subtract(start).Days)
        .Select(offset => start.AddDays(offset))
        .ToArray();

        var dates = new List<DateTime>();

        for (var dt = start; dt <= end; dt = dt.AddDays(1))
        {
            dates.Add(dt);
            richTextBox1.Text = dt.ToString();

        }

Thaks a lot! UPDATED!

https://stackoverflow.com/questions/3738748/create-an-array-or-list-of-all-dates-between-two-dates will get you the dates between two dates. — mjwills, Jun 04 '17 at 11:49
@mjwills Yes, sir. But unfortunately couldn't test it yet. I will answer you in a day if it works — , Jun 06 '17 at 06:02
Define 'it didn't work'. What did you expect? How did it act instead? — mjwills, Jun 08 '17 at 13:01
Also remove the Enumerable.Range code - it doesn't do anything useful unless you assign it to a variable (which you aren't doing). — mjwills, Jun 08 '17 at 13:10
@mjwills, it didn't work again. Richtextbox shows only the last date. P.S. It's a hotel programm, i need to select all dates between arrival and departure day (it is necessary for looking up who is at hotel today). — , Jun 08 '17 at 13:15

Change the code to:

    DateTime start = new DateTime();
    start = dateTimePicker1.Value;
    DateTime end = new DateTime();
    end = dateTimePicker2.Value;

    var dates = new List<DateTime>();
    richTextBox1.Text = "";
    for (var dt = start; dt <= end; dt = dt.AddDays(1))
    {
        dates.Add(dt);
        richTextBox1.Text += dt.ToString();

    }

Thanks a lot @mjwills! And one more, i swear, last question :D This code also adds time, is it possible to add just date, without time? – Jun 08 '17 at 13:21
