Question

I am wondering how I would loop through a datetime or any type of variable to go from 12:00AM to 11:59PM every 30 Mins?

So I need a variable that shows times in 12HR format (01:00PM, 09:00AM) and everytime I loop through it, to add 30 mins to the time? I then need to use this value in a string.

The time needs to start at 10:00AM

And there is always LINQ

var start = DateTime.Today;
var clockQuery = from offset in Enumerable.Range(0, 48)
                 select start.AddMinutes(30 * offset);
foreach (var time in clockQuery)
    Console.WriteLine(time.ToString("hh:mm tt"));

… LINQ + FUNC (for parameterized start)

Func<DateTime, IEnumerable<DateTime>> clockQuery = start =>
    from offset in Enumerable.Range(0, 48)
    select start.AddMinutes(30 * offset);
foreach (var time in clockQuery(DateTime.Today))
    Console.WriteLine(time.ToString("hh:mm tt"));

… or if you just want the TimeSpan offsets …

var start = DateTime.Today;
var clockQuery = from offset in Enumerable.Range(0, 48)
                 select TimeSpan.FromMinutes(30 * offset);
foreach (var time in clockQuery)
    Console.WriteLine((start + time).ToString("hh:mm tt"));
