       {
           TimeSpan ts = offtime.Subtract(ontime);
           txtHrs.Text = ts.Hours.ToString().Replace("-", "");

       protected void txtclose_ValueChanged(object sender, EventArgs e)

           DateTime ontime = Convert.ToDateTime(txtonn.Text.Trim());
           DateTime offtime = Convert.ToDateTime(txtclose.Text.Trim());
           this.CalculateDifference(offtime, ontime);

Solution 1

C#

DateTime dFrom;
DateTime dTo;
string sDateFrom = "11:56:00";
string sDateTo = "12:12:00";
if (DateTime.TryParse(sDateFrom, out dFrom) && DateTime.TryParse(sDateTo, out dTo))
{
      TimeSpan TS = dTo - dFrom;
      int hour = TS.Hours;
      int mins = TS.Minutes;
      int secs = TS.Seconds;
      string timeDiff = hour.ToString("00") + ":" + mins.ToString("00") + ":" + secs.ToString("00");
      Response.Write(timeDiff); //output 16 mins in format 00:16:00
}

Solution 2

Given,

t1=10:00 AM<br />
t2=12:00 PM

To Calculate difference in hours:

C#

DateTime dtFrom = DateTime.Parse("10:00 AM");
DateTime dtTo = DateTime.Parse("12:00 PM");

int timeDiff = dtFrom.Value.Subtract(dtTo.Value).Hours;

timeDiff is the difference in hours you require
