namespace zip {     public class program     {         public static void main()         {             string directorypath = @"c:\users\public\reports";              directoryinfo directoryselected = new directoryinfo(directorypath);              foreach (fileinfo filetocompress in directoryselected.getfiles())             {                 compress(filetocompress);             }              foreach (fileinfo filetodecompress in directoryselected.getfiles("*.gz"))             {                 decompress(filetodecompress);             }         }          public static void compress(fileinfo filetocompress)         {             using (filestream originalfilestream = filetocompress.openread())             {                 if ((file.getattributes(filetocompress.fullname) & fileattributes.hidden) != fileattributes.hidden & filetocompress.extension != ".gz")                 {                     using (filestream compressedfilestream = file.create(filetocompress.fullname + ".gz"))                     {                         using (gzipstream compressionstream = new gzipstream(compressedfilestream, compressionmode.compress))                         {                             originalfilestream.copyto(compressionstream);                             console.writeline("compressed {0} {1} {2} bytes.",                                 filetocompress.name, filetocompress.length.tostring(), compressedfilestream.length.tostring());                         }                     }                 }             }         }          public static void decompress(fileinfo filetodecompress)         {             using (filestream originalfilestream = filetodecompress.openread())             {                 string currentfilename = filetodecompress.fullname;                 string newfilename = currentfilename.remove(currentfilename.length - filetodecompress.extension.length);                  using (filestream decompressedfilestream = file.create(newfilename))                 {                     using (gzipstream decompressionstream = new gzipstream(originalfilestream, compressionmode.decompress))                     {                         decompressionstream.copyto(decompressedfilestream);                         console.writeline("decompressed: {0}", filetodecompress.name);                     }                 }             }         }     } }

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...
