从表格中提取时间数据并将其放入TimeSpan中

Question

在表格中，any1是否知道如何选择指定的行并在指定列中取时间数据，然后将数据放入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

您试过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 
    } 

Answer 2

如果您确定的时间列的文本格式完全正确，你可以使用TimeSpan.Parse()

TimeSpan startTime = TimeSpan.Parse(row["time"].ToString()); 

Answer 3

是的，我用TimeSpan.Parse（）。这是我的代码，它的工作原理！ :)

foreach (DataRow row in RetailCamDataSet1.Tables["smBranchWorkingDayInfo"].Select("ID=" + convertedBranchID)) 
       { 
        var sTime = DateTime.Parse(row["SunFromTime"].ToString()); 
        int sHour = sTime.Hour, 
         sMinute = sTime.Minute, 
         sSecond = sTime.Second; 

        var eTime = DateTime.Parse(row["SunToTime"].ToString()); 
        int eHour = eTime.Hour, 
         eMinute = eTime.Minute, 
         eSecond = eTime.Second; 

        TimeSpan startTime = new TimeSpan(sHour, sMinute, sSecond); 
        TimeSpan endTime = new TimeSpan(eHour, eMinute, eSecond); 
        TimeSpan timeDifference = new TimeSpan(); 

        timeDifference = endTime.Subtract(startTime); 

        double minutes = timeDifference.TotalMinutes; 

        normalCount = minutes/15;
