Parsing a strangely formatted DateTime. Anyone fancy stepping up?

I'm trying to parse a datestamp (that I got from Twitter) but am receiving errors. here's the datestamp:

Fri, 27 Aug 2010 22:00:07 +0000

Here's my code:

DateTime.ParseExact(MyDateValue, "ddd, dd MMM YYYY HH:mm:ss +ffff", new CultureInfo("en-US"))

and here's my error:

System.FormatException was unhandled Message=String was not recognized as a valid DateTime.

Anyone fancy taking that on? To make it easy I've provided the co开发者_如何学JAVAde below for a console app that exhibits the problem.

Thanks Jamie

using System;
using System.Globalization;

class Program
{
    static void Main(string[] args)
    {
        string MyDateValue = "Fri, 27 Aug 2010 22:00:07 +0000";
        var dt = DateTime.ParseExact(MyDateValue, "ddd, dd MMM YYYY HH:mm:ss +ffff", new CultureInfo("en-US"));

    }
}

The year specifier is yyyy, not YYYY:

string MyDateValue = "Fri, 27 Aug 2010 22:00:07 +0000";
var dt = DateTime.ParseExact(MyDateValue, "ddd, dd MMM yyyy HH:mm:ss +ffff", new CultureInfo("en-US"));

The above works fine, as far as that it will not throw an exception.

I am assuming that the +0000 at the end of the string is supposed to be a timezone specifier. If so, the ffff is incorrect, as it stands for The hundred thousandths of a second, not the timezone specifier, which is K. If it is indeed supposed to be the timezone specifier, then this would be the correct code:

string MyDateValue = "Fri, 27 Aug 2010 22:00:07 +0000";
var dt = DateTime.ParseExact(MyDateValue, "ddd, dd MMM yyyy HH:mm:ss K", new CultureInfo("en-US"));

See Custom Date and Time Format Strings.

Should your YYYY be yyyy?

My help file for the custom formatting information for DateTime only has lowercase y's, no uppercase.

Notice the change in year: YYYY->yyyy

DateTime.ParseExact(MyDateValue, "ddd, dd MMM yyyy HH:mm:ss +ffff", new CultureInfo("en-US"))

System.DateTime.ParseExact(MyDateValue, "ddd, dd MMM yyyy HH:mm:ss zzz", new System.Globalization.CultureInfo("en-US"));

The year part needs to be lower-case: ddd, dd MMM yyyy HH:mm:ss +ffff

I dropped the "+0000" and just used DateTime.Parse()

To get to my actual timezone (since +0000 is probably an offset from GMT) I set that as well.

string myDateValue = "Fri, 27 Aug 2010 22:00:07"; //get this using substring
int gmtOffset = -6; //I'm in the Central TimeZone
DateTime dt = DateTime.Parse(myDateValue);
dt.AddHours(gmtOffset);

Console.WriteLine(dt.ToString("ddd, dd MMM yyyy hh:mm:ss"));
