you should typecast the things before comparision.

i.e   xNotField = reader.GetName(fcount).ToString() == "DATA_TYPE" && reader[fcount] .ToString() == "timestamp";

xRead = reader[fcount].ToString();
                                xNotField = reader.GetName(fcount) == "DATA_TYPE" ;
                                xNotField = xNotField & xRead == "timestamp";
                                xNotField = xNotField & xID == xRead;

I had to change it like above to make it work.
