Convert a DateTime to byte[]

[Fabio]

Hi all!

A simple question: I need to convert a DateTime var to a byte[] (or to a
Int64).

How?

Thanks!

datetime.ToOaDate() returns an int, maybe that helps?

greetz,

no - it returns a double; if you wanted to go down this route, .Ticks might
be a reasonable choice...

Yeah, none of the ConvertTo functions are implemented for DateTime. According to Microsoft they all
throw exceptions:
http://msdn.microsoft.com/library/d...html/frlrfSystemConvertClassToInt64Topic4.asp
http://msdn2.microsoft.com/en-us/library/hx1xzhwe.aspx

DateTime.Now.Ticks
should give you the int64 version of the DateTime

Hi,

byte[] b = BitConverter.GetBytes( theDateTime.Ticks);

 

[Fabio]

byte[] b = BitConverter.GetBytes( theDateTime.Ticks);

Thanks to all, this is the right way in, and this the way out:

DateTime d = DateTime.FromBinary(BitConverter.ToInt64(b, 0))
