Hour from DateTime? in 24 hours format

Question

Hello to everyone, So i have this DateTime? and what i want to do is to obtain the hour but show it in 24 hours format.
For example:
If the hour is 2:20:23 p.m. i want to convert it to 14:20 and that's it.

I'm working with Visual C#. Any ideas please, thank you.

I have something like this

public static string FormatearHoraA24(DateTime? fechaHora)
    {
        if (!fechaHora.HasValue)
            return "";

        string retornar = "";
          //here goes what i need
    }

Answer 1

Use date.ToString("HH:mm");

Answer 2

Try this:

//String.Format("{0:HH:mm}", dt);  // where dt is a DateTime variable

public static string FormatearHoraA24(DateTime? fechaHora)
{
    if (!fechaHora.HasValue)
        return "";

    return retornar = String.Format("{0:HH:mm}", (DateTime)fechaHora);
}

Answer 3

return fechaHora.Value.ToString("HH:mm");

Answer 4

date.ToString("HH:mm:ss"); // for 24hr format
date.ToString("hh:mm:ss"); // for 12hr format, it shows AM/PM

Refer this link for other Formatters in DateTime.

Answer 5

Using ToString("HH:mm") certainly gives you what you want as a string.

If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay property:

TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;
