Answer 1

Subtracting two DateTime gives you a TimeSpan which has it's own formatting support using the ToString method.

For example:

DateTime now = DateTime.Now;
DateTime later = now.AddMinutes(10);
TimeSpan span = later - now;

string result = span.ToString(@"hh\:mm");

You can read more here on MSDN .

Answer 2

Try this:

string _time_One = "08:30";
string _time_Two = "08:35";
var span = (DateTime.Parse(_time_One) - DateTime.Parse(_time_Two));
string _timeInterval = string.Format("{0:hh\\:mm}", span);

For reference: Custom TimeSpan Format Strings .

Answer 3

@Lloyd is right here, but to clarify this for your case:

string _time_One = "08:30" ;
string _time_Two = "08:35" ;

TimeSpan ts = DateTime.Parse(_time_One) - DateTime.Parse(_time_Two);
MessageBox.Show(String.Format("Time: {0:00}:{1:00}", ts.Hours, ts.Minutes));

I hope this helps.

Answer 4

string _time_One = "08:30";
string _time_Two = "08:35";

string _timeInterval = (DateTime.Parse(_time_One) - DateTime.Parse(_time_Two)).Duration().ToString();

result=>00:05:00
