c# - Does not return in a json format but instead in a xml format -


i got issue in wcf service library because set webmessegeformat json format, instead returns xml format. how can fix issue? missing something?

thank in advance :)

here code:

public class service : iservice {     [webinvoke(method="get",         requestformat = webmessageformat.json,         uritemplate="{id}/{name}/{age}/{sex}/{address}")]     public response transaction(string id, string name, string age, string sex, string address)     {         return new response()         {             id = id,             name = name,             age = age,             sex = sex,             address = address         };     } }  public class response {     public string id { get; set; }     public string name { get; set; }     public string age { get; set; }     public string sex { get; set; }     public string address { get; set; } }

here app config

    <?xml version="1.0"?> <configuration>    <system.servicemodel>     <services>       <service name="wcfeservicelibrary.service">         <endpoint address="http://phws13:8732/wcfservicelibrary/"                    binding="webhttpbinding"                    contract="wcfservicelibrary.iservice">         </endpoint>       </service>     </services>     <behaviors>       <endpointbehaviors>         <behavior>           <webhttp />         </behavior>       </endpointbehaviors>     </behaviors>   </system.servicemodel>  <startup><supportedruntime version="v4.0" sku=".netframework,version=v4.0"/></startup></configuration>

do need set responseformat webmessageformat.json

 [webinvoke(method = "get",          responseformat = webmessageformat.json,          bodystyle = webmessagebodystyle.wrapped,          uritemplate = "{id}/{name}/{age}/{sex}/{address}")]

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
