Reading Datetime value From Excel sheet

when am trying to read datetime type value from excel sheet it is returning a double value.for example if want to read value '2007-02-19 14:11:45.730' like this, i am getting a double type value .further i am converting this double value using timespan,but not complete successfully because i am getting only this value '2007-02-19 12:00:00 AM'
now i want exact same datetime value as first one. My code is like :-

TimeSpan datefromexcel = new TimeSpan(Convert.ToInt32((range.Cells[rCnt, cCnt] as Excel.Range).Value2), 0, 0, 0);

  DateTime inputdate = new DateTime(1900, 1, 1).Add(datefromexcel);

   arrrow2[cCnt - 1] = inputdate.ToString();

Please help!!! Thanks.

Solution 1:

You need to convert the date format from OLE Automation to the .net format by using DateTime.FromOADate.

double d = double.Parse(b);
DateTime conv = DateTime.FromOADate(d);

Solution 2:

Perhaps you could try using the DateTime.FromOADate method to convert between Excel and .net.
