Answer 1

Maybe this will help:

OdbcConnection con = new OdbcConnection(ConnectString);
con.Open();
OdbcCommand checkcommand = new OdbcCommand("SELECT contents FROM MyTable WHERE MyClause",  con);
OdbcDataReader checkreader = checkcommand.ExecuteReader();
byte[] array = null;
if (checkreader.Read())
    array = (byte[])checkreader.GetValue(0);
else
{
   //Error
   return false;
}

File.WriteAllBytes("C:\\MyImage.jpeg", array);
