I have DateTime variable and want to get it Double value (to be more clear, I need only date part without time so will truncate only integer part). How to do this ?  I need some think like :

       DateTime dt = DateTime.Now;
       double dtDOuble = Convert.ToDouble(dt);

 This produce error &

Very good, thank you! P.S: I use this in SQL Server 2005, it is
double date = Convert.ToSingle(DateTime.Now.ToOADate()) - 2;

and work very well.
