Convert object type to byte[]

[Kimelia Schiles]

Hi,

I would like to know how to convert the value with return type of object to
a byte array. For example:

byte[] photo = ds.Tables[0].Rows["Photo"];

Thanks and have a nice day

If the contents of ds.Tables[0].Rows["Photo"] is an array of bytes, then
all you need to do is cast to byte[]:

byte[] photo = (byte[])ds.Tables[0].Rows["Photo"];

If you're actually trying to convert an object to an array of bytes,
that involves a bit more work and depends on what type you are
converting from (Image or Stream or whatever)

I've seen many useful methods for writing to/from byte[] in the
InteropServices namespace. But somehow I think it won't help you with
ds.. Anyway, have a look ;)
