c# - Request parameter in Windows Mobile for REST API's -

i have 1 windows handheld device application on .net framework 3.5 has requirement of accessing rest api. rest api gives me json output going process later. have following code that:-

        httpwebrequest webrequest;         string result = string.empty;         try         {             webrequest = (httpwebrequest)webrequest.create(url);             webrequest.method = "post";             webrequest.keepalive = false;             webrequest.contenttype = "application/x-www-form-urlencoded";             using (webresponse response = webrequest.getresponse())             {                 using (streamreader streamreader = new streamreader(response.getresponsestream()))                 {                     result = streamreader.readtoend();                 }             }         }         catch (exception ex)         {             result = ex.message;         } 

the url variable holding url api query parameters in it. example "http://www.something.com/login?id=test&pwd=test".

now problem dont want use query string parameters rather want use request parameters because above approach not work every time perfectly. times "unauthorized" error. , have 1 tokenid need send everytime calling api , token id in base64 format.

can please me how can use request parameter feature send parameter values?

use headers property of request object.

webrequest.headers.add("id", "test"); webrequest.headers.add("pwd", "test"); webrequest.headers.add("token", mytoken);
