read settlement opening db picturebox

i have perplexing review settlement saved opening db ole vigilant picturebox c# windows application.

the formula does presented below:

        twine connstring = @"provider=microsoft.jet.oledb.4.0;data source=d:\rajesh\sampledb_2003.mdb;";
        oledbconnection oconn = new oledbconnection(connstring);
        oconn.open();
        twine commandstring = "select * worker where id = " + id + "";
        oledbcommand ocmd = new oledbcommand(commandstring, oconn);
        oledbdatareader oreader = ocmd.executereader(commandbehavior.sequentialaccess);

        while (oreader.read())
        {
            txtid.text = ((int)oreader.getvalue(0)).tostring();
            txtname.text = (string)oreader.getvalue(1);
            txtage.text = ((int)oreader.getvalue(2)).tostring();
            txttype.text = (string)oreader.getvalue(3);
            byte[] imagebytes = (byte[])oreader.getvalue(4);

            memorystream ms = new memorystream();
            ms.write(imagebytes, 0, imagebytes.length);
            bitmap bmp = new bitmap(ms);
            pbpassport.image = bmp;
        }

when i govern above code, an 'parameter valid' difference thrown during line:

bitmap bmp = new bitmap(ms)

from difference message, pristine 'ms' format recognisable. any idea past this?
