Are you expecting to use a standard int conversion, such as one returned from a C++ API, or do you want to make your own ?

You can not convert DateTime object to Int32 but yes you can convert it to Double using ToOADate() method. To generate DateTime object from Double you can use DateTime.FromOADate() method... For Example Double d = DateTime.Now.ToOADate(); ... DateTime.FromOADate(d); Hope this helps you out...

Then you need to decide what representation you want to use. THe old 32bit datetime format from C only supports the range 1970 to ~2038(?). If you need a larger range you'll have to loose some precision at the seconds end of the values.

Well, you realisitically need to invent some way of representing it then. Do you need the time, or just the date. An int is 16 bit, so 0x00000000, you could use one byte for month, one for day and two for year. Or, you could set a base date, and store the date as days from that date. There's all sorts of options.
