Oh, this

 SqlParameter[] parameters = new SqlParameter[2];
  parameters[0] = new SqlParameter("RegistrationID", RegID);
  parameters[1] = new SqlParameter("PersonID", 0);

The general idea is to create as less objects a possible

If this is in a loop (SqlParameter[] parameters = new SqlParameter[2]), say n times, you will create n objects that will have to be collected

So I would put

SqlParameter[] parameters = new SqlParameter[2];

outside the loop


As to, new SqlParameter(), you may try to resuse them, by setting their value - if at all possible
