c# - 从表中提取时间数据并将其放入TimeSpan

Question

在表格中，any1是否知道如何选择指定行并在指定列中取出时间数据，然后将数据放入TimeSpan中？

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

您尝试过TimeSpan.Parse()吗？

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
    }
