c# - Tcp/IP listener parsing xml string output advice(code provided just not working as it should) -

-

i advice on how fix code. it's tcp/ip listener 

requestcount = requestcount + 1; networkstream networkstream = clientsocket.getstream(); byte[] bytesfrom = new byte[1000025]; networkstream.read(bytesfrom, 0, (int)clientsocket.receivebuffersize); string datafromclient =       system.text.encoding.ascii.getstring(bytesfrom);  datafromclient = datafromclient.substring(0, datafromclient.indexof("$"));   var rap= xdocument.parse(datafromclient) .descendants("gag")  .select(n => new {      re= n.element("re").value,            we= n.element("we").value  }).tostring();  console.writeline(" >> data client : " + rap); string serverresponse = "last message client :"  + datafromclient; byte[] sendbytes = encoding.ascii.getbytes(serverresponse); networkstream.write(sendbytes, 0, sendbytes.length); networkstream.flush(); console.writeline(" >> " + serverresponse);

that listens string 

<?xml version="1.0" >  <tt>             <gag>                             <re>monkey</re>                             <we>chicken</we>             </gag>             <sap>                             <re>monkey</re>                             <we>chicken</we>             </sap> </tt>

i attempting show output monkey , chicken in console advice appreciated still whole string please dont post answers in comments

thank much

byte[] bytesfrom = new byte[1000025]; networkstream.read(bytesfrom, 0, (int)clientsocket.receivebuffersize); string datafromclient =       system.text.encoding.ascii.getstring(bytesfrom);

oh, let me count problems:

  • a huge buffer - not sure why; not wrong per se, inadviseable
  • not checking reply read - that's huge problem; how data did read?
  • not looping either read all data, or read frame (logical message) of data
  • assuming ascii - well, maybe ascii; i'd buffer bytes, though

i suspect (assuming client closes outbound socket after send):

// *remove* `read` code etc // ... var rap= xdocument.load(networkstream) // before

and work beautifully.

if client not close outbound socket after send, you're going have harder time of it.

edit: jon notes - you'll need use rap useful.

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...
