c# - sending hex value over for ZRANGEBYLEX -


i using c# 4.5, stackexchange.redis version 1.0.316.0. need send follwoing command reids server search sorted set start aar.

zrangebylex iwu [aar "[aar\xff" limit 1 10

in c# code tried

querystring="aar";  sortedsetrangebyvalue("iwu", querystring, querystring + "\xff",                0, 10);

when monitor on redis server see did not send expected, sent instead.

"zrangebylex" "iwu" "[aar" "[aar\xc3\xbf" "limit" "0" "10"

how can fix c# code send right hex values over?

simply using querystring + @"xff" worked me.

Using Java 8 lambdas/transformations to combine and flatten two Maps -

i have 2 maps: map<a, collection<b>> mapab map<b, collection<c>> mapbc i transform them map<a, collection<c>> mapac , i'm wondering if there's smooth way lambdas , transformations. in particular case, collections sets, i'd solve problem collections in general. one thought had first combine 2 maps map<a, map<b, collection<c>>> , flatten it, i'm open approach. data notes: b should occur in value collection associated 1 a , , same true mapbc (a given c mapped 1 b ). result, there should 1 path given a given c , although there may a -> b mappings there no b -> c mappings , there may b -> c mappings there no corresponding a -> b mappings. these orphans don't appear in resulting mapac . for sake of comparison, here's example of purely imperative approach same problem: map<a, collection<c>> mapac = new hashmap<>(); (entry<a, collection<b>> entry...
