Retrieving timestamp output parameter from SqlCommand

I've got a SqlCommand that executes a SQL Server 2000 stored procedure
which, among other things, returns a timestamp output parameter.

For the life of me, I can't figure out how to assign the value of this
timestamp value to a byte array. I figure it's gotta be simple so what
am I missing here?

Hi David,

byte[] bb = (byte[])sqlCommand1.Parameters[1].Value;

Does this work (assuming Parameters[1] is timestamp)?

Nope. System.InvalidCastException is thrown.

Hi David,

How exactly is your timestamp SqlParameter defined?
Is it int32 perhaps?

Yes that was it. The param was defined as SqlDbType.Int. Changing it to
SqlDbType.Timestamp fixed the problem.

I knew it would be something stupidly obvious. And as usual in these
situations it takes a second pair of eyes to see the mistake. Thanks
for your help.
