c# - Best way to store table like data -

what best way store table data 

         | column 0 | column 1 | column 2 | column 3 | column 4 row 0    | 0.984546 | 0.654564 | 0.467676 | 0.673466 | 50.03333 row 1    | 0.684546 | 0.457564 | 0.467776 | 0.674566 | 45.73335 row 2    | 0.884546 | 0.424564 | 0.445676 | 0.664566 | 12.23333 row 3    | 0.284546 | 0.054564 | 0.237676 | 0.124566 | 45.01333

both max column , row dynamic , coordinates of value important have calculation based on value. it's not database because data different every time , don't want forever there. also, need access. try use linked list double[] it's difficult me locate each of value. speed factor too.

any suggestion on type of collection should use or ways handle it?

i think should declare variable:

list< list<double> > matrix = new list< list<double> >();

later can use matrix.capacity decide number of rows , use same property on each row set number of columns. way wont have memory wasted.

you can use matrix.trimexcess() resize matrix if next data shorter.

the idea behind using matrix.capacity , matrix.trimexcess() have control of how space reserved in data structure. way wont grow , gain performance.

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...
