string was not recognized as a valid datetime

Gnanu

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.

1. try
2. {
3. Console.Write("Please enter date: ");
4. var dateFrom = Console.ReadLine();
5. DateTime formatedDate = DateTime.ParseExact(dateFrom, "dd/MM/yyyy HH:mm", CultureInfo.InvariantCulture);
6. Console.WriteLine("Date in format {0} - {1} ", "dd//MM/yyyyHH:mm", formatedDate);
7. }
8. catch (Exception e)
9. {
10. Console.WriteLine(e);
11. }
12. 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
