How can I convert int 90 minutes to DateTime 1:30?

Question

How can I convert an int 90, for example, to DateTime 1:30 in C# 3.0?

Thanks!!

Answer 1

You shouldn't use a DateTime to represent a span of time - use TimeSpan for that. And in such a case, you'd use this:

TimeSpan ts = TimeSpan.FromMinutes(90);

If you insist that you need a DateTime, you could do the following:

DateTime dt = DateTime.Now.Date; // To get Midnight Today
dt = dt.AddMinutes(90); // to get 90-minutes past midnight Today.

The reason you probably don't want to use DateTime, though, is that it (aptly named) combines the concept of Date with the concept of Time. Your question suggests that you're planning to ignore the date component, so in the interests of using the right tool for the job, I suggest TimeSpan.

If you use C# 4 (VS 2010) you need this snippet:

TimeSpan ts = TimeSpan.FromSeconds(90);
txtDate = string.Format("Full time: {0}", new DateTime(ts.Ticks).ToString("HH:mm:ss"));

it output

Full time: 00:01:30

Answer 3

Or if you're trying to add time to a DateTime with just a date:

DateTime dt = dateTime.AddMinutes(90);
