c# - iterate .net dictionary as object -

-

i have interesting problem. need write general (i'd use word "generic" conflict i'm after) routine can hand instance of dictionary object instance , iterate on content of said object dictionary , return content literal values. difficulty lies in method parameter of type "object", not dictionary.

what need , can't figure out how do, way of iterating on dictionary<k, v> of arbitrary keys , values. easy if know types going in, say, origin of dictionary object object.gettype().getinterfaces() has typeof(idictionary) in results. won't know (and shouldn't need know) dictionary key type or value type.

my current need process dictionary<string, someclass>;. once list of keys can use foreach on each instance, figure out it's string , proceed there. values it'll instance of class (the class change again, can pass off set of methods extract class, extract properties of class , extract values).

the main point of request obtain method (or 2 or many) allow me iterate on dictionary of unknown types , extract keys , values, without knowing types @ compile time. above dictionary; example, need able pass dictionary. @ moment, i'm not worried edge cases dictionary<tuple<int, string, someotherclass>, someclass>> or things that, if can start dictionary<string, someclass>;, can proceed there.

it's getting keys , values out in form can process haven't figured out how yet.

you mentioned have access idictionary<k,v> interface on object. can use get_keys , get_values access keys , values respectively.

also, idictionary<k,v> derives ienumerable<keyvaluepair<k,v>> can access list of key-value pairs using for-loop similar lists.

edit - clarification:

idictionary inputasdictionary = input idictionary; if (inputasdictionary != null) {     // valid :  input dictionary.     icollection dictkeys = inputasdictionary.keys; // list of keys     icollection dictvalues = inputasdictionary.values; // list of values      // iterate on keys     for(var dictkey in dictkeys)     {         console.writeline(dictkey); // print key         type dictkeytype = dictkey.gettype(); // type of key if required         // ...     }      // similarly, iterate on values     for(var dictvalue in dictvalues)     {         console.writeline(dictvalue); // print value         type dictvaluetype = dictvalue.gettype(); // type of value if required         // ...     } }

you can using generic dictionary<k,v> interface, gets lot more complicated types. need call type.generictypearguments , go there. example have shown seems simpler.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
