model view controller - running total by linq : place results in paged List -


i try place results of below link in paged list:

linq sql , running total on ordered results

i change code :

var userdocs = db.docs.asqueryable();  int64 running_total = 0; var moeen = userdocs.tolist()                        .orderby(a => a.docdate)                        .select(a =>                                    {                                        running_total += 1;                                        return new moeenviewmodel                                        {                                            doc = a,                                            remain = running_total                                        };                                    }                               );  return view(moeen.topagedlist(1, 15));

but 'remain' results don't start 1. start 8 example if 'docs' records count 7

why ??? !!!

if return view(moeen) results ok

i find problem

var userdocs = db.docs.asqueryable();  int64 running_total = 0; var moeen = userdocs.tolist()                        .orderby(a => a.docdate)                        .select(a =>                                    {                                        running_total += 1;                                        return new moeenviewmodel                                        {                                            doc = a,                                            remain = running_total                                        };                                    }                               ); moeen = moeen.tolist(); return view(moeen.topagedlist(1, 15));

before list moeen .tolist(), every use of moeen cause side effect on running_total.

see : http://www.blackwasp.co.uk/linqrunningtotal.aspx

if change value of variable has been closed on before executing query, results affected.
