Signing into drupal website remotly using C#.net and json -

i want create form in c#.net can sign me in through drupal website. service 3.x module enabled , rest server running on website correctly. problem how serialize username , password json format?

finally solution :

i've got windows form , contains textbox , masked-textbox , button (called button3 below) ,

on button click event , textbox , maskedtextbox contents placed in user object constructed using class :

class user {     public string username;     public string password;     public string name;     public string number;     public string address;     public string email;      public user(string user, string pass, string name = "", string number = "", string address = "", string email = "")     {         this.username = user;         this.password = pass;         this.name = name;         this.number = number;         this.address = address;         this.email = email;     } } 

then converted object json model using json.net library

in rest makes request incoming cookie store in cookiejar , rest requests must copy cookiecontainer request cookiecontainer , stay logged in. rest of code :

        private void button3_click(object sender, eventargs e)     {         cookiecontainer cookiejar = new cookiecontainer();         user user = new user(textbox1.text,maskedtextbox1.text);         string url = "http://"your-web-address"/"your-rest-service"/?q="your-resurce"/user/login.json";         try         {             var request = (httpwebrequest)webrequest.create(url);                       request.contenttype = "application/json";             request.method = "post";             request.cookiecontainer = cookiejar;              using (var streamwriter = new streamwriter(request.getrequeststream()))             {                 string query = jsonconvert.serializeobject(user);                  streamwriter.write(query);                 streamwriter.flush();                 streamwriter.close();             }             var response = (httpwebresponse)request.getresponse();             using (var streamreader = new streamreader(response.getresponsestream()))             {                 var responsetext = streamreader.readtoend();             }      //check see if you're logged in             url = "http://web-address/rest-server/?q=resurce/system/connect.json";             var newrequest = (httpwebrequest)webrequest.create(url);             newrequest.cookiecontainer = cookiejar;             newrequest.contenttype = "application/json";             newrequest.method = "post";               var newresponse = (httpwebresponse)newrequest.getresponse();             using (var newstreamreader = new streamreader(newresponse.getresponsestream()))             {                 var newresponsetext = newstreamreader.readtoend();             }           }         catch(exception ex)         {             messagebox.show(ex.tostring(), "can't access server");         }     }
