DateTime.ParseExtract参数不正确的问题

Question

I have the following line. DateTime.ParseExact("08-11-2013 07:38:05", "yyyy-MM-dd HH:mm:ss", Nothing)

It throws an error.

Parameter is incorrect.

StackTrace

at System.DateTimeParse.ParseExact(String s, String format, DateTimeFormatInfo dtfi, DateTimeStyles style) at System.DateTime.ParseExact(String s, String format, IFormatProvider provider)

Thanks in advance.

Your format doesn't match that date you are providing, It should be:

"dd-MM-yyyy HH:mm:ss"

Considering you meanr November 8, 2013

You code should be:

DateTime dt = DateTime.ParseExact("08-11-2013 07:38:05", 
                                  "dd-MM-yyyy HH:mm:ss", 
                                   CultureInfo.InvariantCulture); // Instead of Nothing

You can also use "dM-yyyy HH:mm:ss" format, since it will consider both single digit/double digit day and month.

Also it appears that you are coming from VB.Net back ground, where Nothing is default value, in C# you can use null for your case or better to use CultureInfo.InvariantCulture
