remove seconds from timespan using c#

问题

I want to remove the seconds from timespan using c#

My code is here:

TimeSpan lateaftertime = new TimeSpan();
lateaftertime =  lateafter - Convert.ToDateTime(intime) ;

It returns the value 00:10:00

But i want the below output :00:10 only not seconds field :00.

Well you can simply do as

string.Format("{0}:{1}", ts.Hours,ts.Minutes) // it would display 2:5

EDIT

to get it properly formatted use

string.Format("{0:00}:{1:00}", ts.Hours,ts.Minutes) // it should display 02:05

Note that a TimeSpan does not have a format. It's stored in some internal representation which does not resemble 00:10:00 at all.

The usual format hh:mm:ss is only produced when the TimeSpan is converted into a String, either explicitly or implicitly. Thus, the conversion is the point where you need to do something. The code example in your question is "too early" -- at this point, the TimeSpan is still of type TimeSpan.

To modify the conversion to String, you can either use String.Format, as suggested in V4Vendetta's answer, or you can use a custom format string for TimeSpan.ToString (available with .NET 4):

string formattedTimespan = ts.ToString("hh\\:mm");

回答3:

TimeSpan newTimeSpan = new TimeSpan(timeSpan.Hours, timeSpan.Minutes, 0);
