Sum Time (HH:MM) in RDLC

问题

I have and RDLC report an I need to get the sum of the fild "Time". I save it in the database with varchar type with the format "hh:mm".

I get this with the formula:

=(Sum(System.TimeSpan.Parse(Fields!HorasEfectivas.Value).Hours))
&":"&
Sum(System.TimeSpan.Parse(Fields!HorasEfectivas.Value).Minutes))

The problem here is the sum of the minutes. 140 minutes shoul be transformed in hours! How can I get this? Regards

回答1:

try using TimeSpan e.g.

      var time1 = new TimeSpan(0,2,02,0);
      var time2 = new TimeSpan(0, 5, 02, 0);

      var totalHours = time1 + time2;
