.net - Returning indexed property from anonymous type -


my linq query returns totals each month of year, i'm exposing twelve properties (named january, february, march...) of anonymous type. makes impossible loop through twelve values. there way instead return single indexed property containing 12 values?

this have:

dim mytotals = aggregate costrow in alltargetrows _                january = sum(costrow.january),                      february = sum(costrow.february),                      march = sum(costrow.march), _                     ...                     total = sum(costrow.total)

this want achieve (compiler doesn't one):

dim mytotals = aggregate costrow in alltargetrows _                values = {sum(costrow.january),                                sum(costrow.february),                                sum(costrow.march), _                               ...                               },                     total = sum(costrow.total)

i able mytotals.values(i) kind of stuff.

the first thing pops mind me use aggregate function populate dictionary. this:

dim mytotals =     alltargetrows     .aggregate(         new dictionary<string, int>()             {                 { "january", 0 },                 { "february", 0 },                 { "march", 0 },                 { "april", 0 },                 { "may", 0 },                 { "june", 0 },                 { "july", 0 },                 { "august", 0 },                 { "september", 0 },                 { "october", 0 },                 { "november", 0 },                 { "december", 0 },                 { "total", 0 }             },         (acc, costrow) =>              {                 acc["january"] += costrow.january;                 acc["february"] += costrow.february;                 acc["march"] += costrow.march;                 acc["april"] += costrow.april;                 acc["may"] += costrow.may;                 acc["june"] += costrow.june;                 acc["july"] += costrow.july;                 acc["august"] += costrow.august;                 acc["september"] += costrow.september;                 acc["october"] += costrow.october;                 acc["november"] += costrow.november;                 acc["december"] += costrow.december;                 acc["total"] += costrow.total;                 return acc;             });

this result in dictionary keys months of year (and 'total') , values sums of values each month.

sorry, missed vb.net tag. vb.net not strong suit think equivalent in vb.net.

dim mytotals = _     alltargetrows _     .aggregate( _         new dictionary(of string, integer) { _             {"january", 0}, _             {"february", 0}, _             {"march", 0}, _             {"april", 0}, _             {"may", 0}, _             {"june", 0}, _             {"july", 0}, _             {"august", 0}, _             {"september", 0}, _             {"october", 0}, _             {"november", 0}, _             {"december", 0}, _             {"total", 0} _         }, _         function(acc, costrow)              acc("january") += costrow.january             acc("february") += costrow.february             acc("march") += costrow.march             acc("april") += costrow.april             acc("may") += costrow.may             acc("june") += costrow.june             acc("july") += costrow.july             acc("august") += costrow.august             acc("september") += costrow.september             acc("october") += costrow.october             acc("november") += costrow.november             acc("december") += costrow.december             acc("total") += costrow.total             return acc         end function)

i not know if overload of aggregate function can converted query syntax. (possibly simpler) alternative forego linq altogether , create dictionary before running query , loop on each row , populate dictionary way. this:

dim mytotals = _     new dictionary(of string, integer) { _         {"january", 0}, _         {"february", 0}, _         {"march", 0}, _         {"april", 0}, _         {"may", 0}, _         {"june", 0}, _         {"july", 0}, _         {"august", 0}, _         {"september", 0}, _         {"october", 0}, _         {"november", 0}, _         {"december", 0}, _         {"total", 0}}  each costrow alltargetrow in alltargetrows     mytotals("january") += costrow.january     mytotals("february") += costrow.february     mytotals("march") += costrow.march     mytotals("april") += costrow.april     mytotals("may") += costrow.may     mytotals("june") += costrow.june     mytotals("july") += costrow.july     mytotals("august") += costrow.august     mytotals("september") += costrow.september     mytotals("october") += costrow.october     mytotals("november") += costrow.november     mytotals("december") += costrow.december     mytotals("total") += costrow.total next

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
