谁能告诉我为什么以下情况不会发生？

List<DateTime> timestamps = new List<DateTime>();
timestamps.Add(DateTime.Parse("8/5/2011 4:34:43 AM"));
timestamps.Add(DateTime.Parse("8/5/2011 4:35:43 AM"));
foreach(DateTime x in timestamps)
{
    if (Object.ReferenceEquals(x, timestamps.First()))
    {
        // Never hit
        Console.WriteLine("hello");
    }
}
