c# - How do I loop through a time range

Question

I would like to define the start time as 6pm and end time as 9pm. This time range (something looked like below) used for everyday's schedule. How do I implement in for loop? Appreciate for any reply.

6:00 PM 
6:30 PM 
7:00 PM 
7:30 PM 
8:00 PM 
8:30 PM 
9:00 PM

Solution 1

you could use while loop

var startTime = DateTime.Parse("2012-01-28 18:00:00");
var endTime = startTime.AddHours(3);
while (startTime <= endTime)
{
  System.Console.WriteLine(startTime.ToShortTimeString());
  startTime = startTime.AddMinutes(30);
}

Solution 2

Simple example with TimeSpan:

for (int minutes = 6 * 60; minutes <= 9 * 60; minutes += 30)
{
    Console.WriteLine(TimeSpan.FromMinutes(minutes));
}
