c# - How to handle Dictionary Key case sensitivity -


all. trying code word replacement tool find , replace multiple words @ once. here's code:

idictionary<string, string> worddict = new dictionary<string, string>(); worddict[wordstofind.text] = wordstoreplace.text; string texttoreplace = article.text; foreach (keyvaluepair<string, string> entry in worddict) {         texttoreplace = texttoreplace.replace(entry.key, entry.value); }

worddict key,value array key word find , value word replace found word with. example, 1 entry in dictionary drone->dog.

wordstofind.text , wordstoreplace.text should self-explanatory. i'm demonstrating how worddict dictionary setup.

the article.text variable textblock has words needs replacing.

the problem running when word replacer hits capitalized words , doesn't recognize them word replace (case-sensitive).

without lowercasing , replacing way (or, i'll go lowercasing if have way retain original casing in output), trying find way detect capitalized words, first letter capitalized, , replace accordingly same casing replacement word when words in worddict variable lowercased.

you use regex.replace:

idictionary<string, string> worddict = new dictionary<string, string>(); worddict[wordstofind.text] = wordstoreplace.text; string texttoreplace = article.text; foreach (keyvaluepair<string, string> entry in worddict) {     texttoreplace = regex.replace(texttoreplace, entry.key, entry.value, regexoptions.ignorecase); }

but if original word example 'drone' (d uppercase) , replacement 'dog' d of dog still lowercase, need differently.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
