C# - How To Validate DateTime ( make “20120713” OR “120713” TO “13.07.2012” )

Question

I\'m trying to parse a DateTime from EDI-Order ( \"20120713\" / YYYYMMDD or \"120713\" / YYMMDD or even other dates WITHOUT dots, so just numbers ) to a valied Date like \"DD.MM

Answer 1

This should work for multiple formats

DateTime Result = new DateTime();
string[] dateFormats = new string[]{ "YYYYMMDD", "YYMMDD", /*other formats you might need*/ };

if (dateFormats.Any(format => DateTime.TryParseExact("yourDate", format, System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, out Result)))
{ /* Result contains the parsed DateTime and you can use it*/ }
else 
{ /* DateTime couldn't be parsed for any format you specified */ }
