I can't figure it out, where did I go wrong?
I got the following datetime string, and need to parse it to datetime:
string timestr = "1/20/2014 12:05:16 AM"
And I trying to parse it like this:
DateTime.ParseExact( timestr,
"MM/dd/yyyy hh:mm:ss tt",
null);
When trying to do this it returns
"string was not recognized as a valid DateTime"
Any tip?
MM is for 01 to 12
Use M instead which is for 1 to 12.
string timestr = "1/20/2014 12:05:16 AM";
var date = DateTime.ParseExact(timestr,
"M/dd/yyyy hh:mm:ss tt",
CultureInfo.InvariantCulture);
Console.WriteLine(date);
Output will be;
1/20/2014 12:05:16 AM
Here a demonstration.
For more information, take a look at;
Also be careful about your hour formatting. hh is for 01 to 12, HH is for 00 to 23. If your hour will be 13, 14 or 15 etc.. hh format will fail.
And since you using null as a IFormatProvider in your DateTime.ParseExact method, that means it uses CurrentCulture by default. And if it's DateSeparator is not /, your method throws FormatException even your string and format matches exactly because "/" format specifier has a special meaning in custom date and time formats like; replace me current culture's or suplied culture date separator
Did you try
DateTime returnedDate = new DateTime();
DateTime.TryParse(timestr, out returnedDate);
CurrentCulture doesn't accept M/dd/yyyy hh:mm:ss tt as a standard date and time pattern, your DateTime.TryParse returns false and your returnedDate will be 01/01/0001 00:00:00.M-The month, from 1 through 12.
The "M" custom format specifier represents the month as a number from 1 through 12 (or from 1 through 13 for calendars that have 13 months). A single-digit month is formatted without a leading zero.
DateTime.ParseExact( timestr,"M/dd/yyyy hh:mm:ss tt",CultureInfo.InvariantCulture);
PLease try
string timestr = "1/20/2014 12:05:16 AM";
DateTime dt = new DateTime();
DateTime.TryParse(timestr, out dt);
out parameter by the way. DateTime dt; will be enough.CurrentCulture doesn't accept M/dd/yyyy hh:mm:ss tt as a standard date and time pattern, your DateTime.TryParse returns false and your dt will be 01/01/0001 00:00:00.Try this one:
this.RequestDate = Convert.ToDateTime(this.DcmCreateDate).ToString("dd/MM/yyyy");
