c# - Select Files From Folder Depending on Name Convention -


i receive bunch of xml files in folder.

i want keep checking files have following naming convention:

sr-{first_id}-{second_id}-matchresults.xml

to parse receive one.

for example:

sr-40-24-standings.xml sr-40-24-results.xml sr-40-24-j7844-matchresults.xml

i should select 1 : sr-40-24-j7844-matchresults.xml

what comes after helps me select files depending on naming convention asp web service?

 dim files io.fileinfo() = foldername.getfiles("*.xml") 

private bool isvalid(string value)     {         string regexstring = "^sr-([a-z0-9]+)-([a-z0-9-]+)-matchresults.xml";         return regex.ismatch(value, regexstring);     }

this method give files specified format (sr-{first_id}-{second_id}-matchresults.xml). note: ids can contain alphanumeric characters "-" symbol. if don't want symbol in id, code like,

string regexstring = "^sr-([a-z0-9]+)-([a-z0-9]+)-matchresults.xml";

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...
