When I set a valid DateTime on one of the date properties of the ContentDisposition object, I get an error when I try retrieve the date. It seems the error occurs if the hour, minute, or second component of the DateTime is 0. I tracked down the issue to the MailBnfHelper.ReadDateNumber method using Reflector, it throws a FormatException if the number it reads is 0.

Here is some code that will reproduce the issue:

using System;
using System.Net.Mime;

class Program
{
static void Main(string[] args)
{
var disposition = new ContentDisposition();

TrySetGetCreationDate(disposition, new DateTime(2009, 12, 1, 0, 1, 1));
TrySetGetCreationDate(disposition, new DateTime(2009, 12, 1, 1, 0, 1));
TrySetGetCreationDate(disposition, new DateTime(2009, 12, 1, 1, 1, 0));

Console.WriteLine("Press [Enter] to exit");
Console.ReadLine();
}
private static void TrySetGetCreationDate(ContentDisposition disposition, DateTime date)
{
try
{
disposition.CreationDate = date;
Console.WriteLine("Creation Date: " + disposition.CreationDate);
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
