Hi guys ;

 

I have a question about FTP method ,the WebRequestMethods.Ftp.ListDirectoryDetails;

return this format " 06-04-15 09:03PM 1127652 filenamze.zip " 

 

I want to change date format such as 2015-06-04 or 04-06-2015

 

Data Column is ;  new DataColumn("Last modified", typeof(string))});

 

if I change to datacolumn type as Datetime ,the respond return below error

 

String was not recognized as a valid DateTime.Couldn't store <05-21-15> in Last modified Column. Expected type is DateTime.
