how to compare two times using DateTime object. I need to compare hours & minutes only based on this i am showing some message.

If DateTimeObject1.TimeOfDay = DatTimeObject2.TimeOfDay Then<br />
 'do something<br />

Is there a way that I'm just not aware of?

static public implicit operator byte[](MyClass m)
{
   return (byte[])m.buffer.Clone();
}
