Have you put a breakpoint on the line? What does the PublishDate hold?

Is it a string? If so, you might need to do a DateTime.Parse() or DateTime.TryParse().

Or the date might just be in an invalid format. Thus the first line of questions above.

You can do the following:

  DateTime dt = ((DateTimeOffset)g.Attributes["PublishDate"]).DateTime;
