c# - Combine query and use 1 datareader -


i want receive 2 values datareader. don't know how put 1 query. , how can receive using 1 sqldatareader?

 string query = "select date ars.kmstand ritnr=(select max(ritnr) ars.kmstand)";         string query2 = "select nr ars.kmstand ritnr=(select max(ritnr) ars.kmstand)";         sqlcommand com = new sqlcommand(query2, conn);         sqldatareader rt = com.executereader();         while (rt.read())         {             ritnr = rt.getint32(0);         }         rt.close();         sqlcommand comm = new sqlcommand(query, conn);         sqldatareader rd = comm.executereader();         while (rd.read())         {             value = rd.getsqldatetime(0);         }

combine queries , pass column index getxxx methods of idatareader value of each column result set.

string query = "select nhr, date ars.kmstand ritnr=(select max(ritnr) ars.kmstand)"; sqlcommand com = new sqlcommand(query, conn); sqldatareader rt = com.executereader(); while (rt.read())  {     int nhr = rt.getint32(0);     sqldatetime date = rt.getsqldatetime(1); } rt.close();
