How to parse a string to DateTime with “yyyyMMdd Hmm” format?

Question

I\'m having huge problems with solving this problem. I\'m trying to parse a string using Datetime.ParseExact().

I have the following code:

DateTime.P

Since H specifier can be 2 digit, this method try to parse your 83 with H specifier. Since there is no such an hour, you get FormatException.

For your case, one way to prevent this is putting a leading zero just before your 8.

var s = "20151210 832";
var result = s.Split(' ')[0] + " 0" + s.Split(' ')[1];
var dt = DateTime.ParseExact(result, "yyyyMMdd Hmm", CultureInfo.InvariantCulture);

Be aware, this will not work for all cases. For example, if your hour part already two digit, if your single minute does not have leading zero.. etc.

Or you can put delimiter for your all parts but in such a case, you need to manipulate both your string and format.

.NET Team suggest this way as well.
