I have timespan : "P3M10DT5H2M" I m trying to parse with these codes:

var timespan =  "P3M10DT5H2M"
string[] formats = new[] { "'PT's'S'", "'PT'm'M'", "'P'd'D'", "'PT'h'H'", "'P'd'DT'h'H'", "'P'd'DT'h'H'm'M'", "'PT'h'H'm'M'", "'P'd'DT'h'H'm'M's'S'", "'P'm'M'd'DT'h'H'm'M'" };
TimeSpan.ParseExact((string)timespan , formats, CultureInfo.InvariantCulture);

But this error occurs: A first chance exception of type 'System.FormatException' occurred in mscorlib.dll

Additional information: String was not recognized as a valid TimeSpan.

The last format should be match for this string but not why? And also the other question my way is not so good. Because I have to write all possibilities in formats. So Should I use regular expressions instead of formats array. Please help me.

variable `timespan` and `tmespan` are not the same. – NeverHopeless Sep 16 '15 at 06:13
I edited now, sorry. But it s not because of that. – Kle Sep 16 '15 at 06:14
Please parse "P3M10DT5H2M" **manually** so that we know what its parts are. Specifically you have two "M"s what do they mean? – Ehsan88 Sep 16 '15 at 06:25
First one is for month, other one for minute. The time is actually 3 months,10 Days,5 Hours, 2 Minutes – Kle Sep 16 '15 at 06:26
How did you setup these `formats`? Are these standard formats ? – NeverHopeless Sep 16 '15 at 06:32

Yes these are .NET TimeSpans to ISO 8601 Duration strings. – Kle Sep 16 '15 at 06:33

Did you consider using `System.Xml.XmlConvert.ToTimeSpan()`? – elimad Sep 16 '15 at 06:39
