I'm trying to convert date format but its exception, string was not in valid date time. string FROM = DtpFrom.Value.ToString(); DateTime mfromdt = DateTime.ParseExact(FROM, "dd/MM/yyyy HH:mm", CultureInfo.InvariantCulture); FROM = mfromdt.ToString(); this is my code, i'm getting exception at DateTime mfromdt and getting DtpFrom.value="8/23/2019 6:36:46 PM"(in MM/dd/yyyy) format. Thanks in advance!

ParseExtract function requires the exact date format that has having that value. Doing so will resolve the issue.

try { Console.Write( "Please enter date: " ); var dateFrom = Console.ReadLine(); DateTime formatedDate = DateTime.ParseExact(dateFrom, "dd/MM/yyyy HH:mm" , CultureInfo.InvariantCulture); Console.WriteLine( "Date in format {0} - {1} " , "dd//MM/yyyyHH:mm" , formatedDate); } catch (Exception e) { Console.WriteLine(e); } Console.ReadLine(); Now if you enter date 25/08/2008, this will given an exception because we have not provided time in the given date System.FormatException: String was not recognized as a valid DateTime. at System.DateTimeParse.ParseExact(String s, String format, DateTimeFormatInfo dtfi, DateTimeStyles style) at System.DateTime.ParseExact(String s, String format, IFormatProvider provider) at StringAlogrithms.Program.Main(String[] args) in C:\Personal Data\Projects\StringAlogrithms\StringAlogrithms\Program.cs:line 31 correct date : 25/08/2008 - this will give the expected result Date in format dd//MM/yyyyHH:mm - 25-Aug-08 2:05:00 PM Please accept this answer if you find helpful

DateTime date = DateTime.Now; string dateValue = string .Format( "{0:MM/dd/yyyy}" , date); the above method will work for you. replace ' date ' to your DateTime's variable .
