To piggy back off of davecoulter, if you need to do this all over your application for your DateTime objects, you might want to define an extenion method for your DateTime object.

void Main()
{
    DateTime today = new DateTime(2011, 8, 29);
    DateTime nextWeek = new DateTime(2011, 9, 4);

    foreach (DateTime dateTime in today.ListAllDates(nextWeek))
    {
       Console.WriteLine(dateTime);
    }
    Console.ReadLine();
}

public static class DateTimeExtenions
{
    public static IEnumerable<DateTime> ListAllDates(this DateTime lhs, DateTime futureDate)
    {   
        List<DateTime> dateRange = new List<DateTime>();
        TimeSpan difference = (futureDate - lhs);
        for(int i = 0; i <= difference.Days; i++)
        {
            dateRange.Add(lhs.AddDays(i));
        }
        return dateRange;
    }
}

You can copy this straight into LinqPad and run as program to test it out.
