Question

I have a sample date

DateTime startDate = DateTime.Parse("2011-01-01 00:00:00");
DateTime endDate = DateTime.Parse("2011-01-03 01:01:03");

How can I get it to Elapsed time of 49:01:03? I can’t get any string format including days.

Currently I want to use that on DataGridView’s Columns.

Below is the sample code of it:

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
    e.Column.CellTemplate.Style.FormatProvider = new DayToHour();
    //e.Column.CellTemplate.Style.Format = "";
}

But I can’t get it work :(.

Note: I don’t have any problem on subtracting the date and time. I’m asking about the format.

Closed: Just used wrapper class inheriting from IFormatProvider.

Answer 1

I think there might no such format available so you will have to get the value on these lines

TimeSpan diff = endDate - startDate;
String.Format("{0:00}hr {1:00}mn {2:00}sec",
                     Math.Truncate(diff.TotalHours),diff.Minutes,diff.Seconds);

Also have a look at this Custom Format provider
