C# List of Schedules [on hold]

C# List of Schedules [on hold]

I have to create a box that contains a list with day hours separated by
interval
How to do a list like this:
<li>...</li>
<li>08:00</li>
<li>08:45</li>
<li>09:30</li>
<li>...</li>
[...] using C# for(var i...) { } or something like that.
The time could start/finish any time. And the interval not necessary need
to be always 45 mim.
Update
I found something here:
C# loops through 24 hours every 30 minutes
