string was not recognized as a valid datetime

Question

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!
