Question

Inside a table, does any1 know how to select a specified row and take a Time data in a specified column, then put the data inside TimeSpan?

DataRow[] selectIDRow = RetailCamDataSet1.Tables["smBranchWorkingDayInfo"].Select("ID=" + ID);
foreach (DataRow row in getTimeDifference)
{
    TimeSpan startTime = new TimeSpan(); //Need to put the data into the bracket instead of using hard code

     TimeSpan endTime = new TimeSpan(20, 00, 00); //Hard coded
     TimeSpan timeDifference = new TimeSpan();

     timeDifference = endTime.Subtract(startTime);

     double minutes = timeDifference.TotalMinutes;

     normalCount = minutes / 15;

Answer 1

Have you tried TimeSpan.Parse()?

DataRow[] selectIDRow = RetailCamDataSet1.Tables["smBranchWorkingDayInfo"].Select("ID=" + ID);
    foreach (DataRow row in getTimeDifference)
    {
         DateTime dateTime = DateTime.Parse(row["DateTimeColumn"].ToString());
         TimeSpan timeSpan = TimeSpan.Parse(dateTime.ToString("hh:mm:ss"));
         ... //do whatever you want to do with timeSpan
    }
