Hour from DateTime? in 24 hours format

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
}

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

Refer [this][1] link for other Formatters in DateTime.

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;

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);
}

Try this, if your input is string
For example

string input= "13:01";
string[] arry = input.Split(':');
string timeinput = arry[0] + arry[1];
private string Convert24To12HourInEnglish(string timeinput)

{

DateTime startTime = new DateTime(2018, 1, 1, int.Parse(timeinput.Substring(0, 2)),
int.Parse(timeinput.Substring(2, 2)), 0);
return startTime.ToString("hh:mm tt");

}
out put: 01:01

You can get the desired result with the code below. Two 'H' in `HH` is for 24-hour format.

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