如何以自定义格式显示汇总的TimeSpans？

Question

I need your help with following problem:

I have an ASP.net Grid View and I want to sum times in gridview on cell text and if result is more than 24 Hours then I don't want Days appearing, I need only hours and minutes ( 45:12 ). I'm using following code. Please Help.

protected void grvCustomers_RowDataBound(object sender, GridViewRowEventArgs e)
{
    TimeSpan sum3 = TimeSpan.Zero;
    if (e.Row.RowType==DataControlRowType.DataRow)
    {
        string tt3 = e.Row.Cells[4].Text;

        sum3 += TimeSpan.Parse(tt3);

        llate.Text = string.Format("{0}:{1}", (int)sum3.TotalHours, sum3.Minutes);
    }
} 

Answer 1

To add together TimeSpan s and format the result as total hours and minutes, try something like the following:

TimeSpan ts1 = TimeSpan.Parse("21:15");
TimeSpan ts2 = TimeSpan.Parse("14.23:02");
ts1 += ts2;

string hoursMinutes = string.Format("{0:00}:{1:00}", ts1.TotalHours, ts1.Minutes);

Answer 2

use like this:

var j = string.Format("{0:00}",1); //output : 01
var j = string.Format("{0:00}",10); //output : 10

Can use this too:

var i = 10.ToString().PadLeft(2, '0'); //output : 10
var i = 1.ToString().PadLeft(2, '0'); //output : 01
