c# - Count Rows in Linq -

-

i new in linq

i have written following query :

var duplicate =      loginid in dataworkspace.v2oneboxdata.me_employees     loginid.me_login_name == this.me_login_name               && loginid.me_pkey != this.me_pkey     select loginid;

i want count rows returned in result duplicate

i searched many of articles says use duplicate.count(). dont see count() in intelisense

how count result

how doing using extension methods:

 var count = me_employees.where(me => me.me_login_name == this.me_login_name && me.me_pkey != this.me_pkey).count();

even better:

var count = me_employees.count(me => me.me_login_name == this.me_login_name && me.me_pkey != this.me_pkey);

big note: ensure have referenced system.core. system.data.linq assume referenced it.

i know __call__ method in class triggered when instance of class called. however, have no idea when can use special method, because 1 can create new method , perform same operation done in __call__ method , instead of calling instance, can call method. i appreciate if gives me practical usage of special method. django forms module uses __call__ method nicely implement consistent api form validation. can write own validator form in django function. def custom_validator(value): #your validation logic django has default built-in validators such email validators, url validators etc., broadly fall under umbrella of regex validators. implement these cleanly, django resorts callable classes (instead of functions). implements default regex validation logic in regexvalidator , extends these classes other validations. class regexvalidator(object): def __call__(self, value): # validation logic class urlvalidator(regexvalidator): def __call__(self, valu...
