String not getting converted to datetime

Question

I have I have Excel file from where I am getting date in string format as "30-12-1899 07:50:00:AM"

When I am trying to convert it to DATETIME then it is giving error as

String was not recognized as a valid DateTime

I am trying to convert it like this

Convert.ToDateTime(homeToSchool[7],new DateTimeFormatInfo { ShortDatePattern = "dd-MM-yyyy", DateSeparator = "-" })

Answer 1

Use DateTime.ParseExact

string myDate = "30-12-1899 07:50:00:AM";
DateTime dt1 = DateTime.ParseExact(myDate, "dd-MM-yyyy hh:mm:ss:tt", 
                                           CultureInfo.InvariantCulture)
