How to extract a JSON Array entry in C# for Infopath -

i new programming. wanted create c# infopath button send sms when clicked. went except response server. able display response, want display part of web response. here code:

using microsoft.office.infopath; using system; using system.xml; using system.xml.xpath; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks; using system.io; using system.net; using system.web; using system.web.script.serialization; //using system.json; using newtonsoft.json;    namespace sms_form_fields {     public partial class formcode     {         // member variables not supported in browser-enabled forms.         // instead, write , read these values formstate         // dictionary using code such following:         //         // private object _membervariable         // {         //             //     {         //         return formstate["_membervariable"];         //     }         //     set         //     {         //         formstate["_membervariable"] = value;         //     }         // }          // note: following procedure required microsoft infopath.         // can modified using microsoft infopath.         public void internalstartup()         {             eventmanager.formevents.submit += new submiteventhandler(formevents_submit);          }          public void formevents_submit(object sender, submiteventargs e)         {              var uribuilder = new uribuilder("http://smsgateway.me/api/v3/messages/send/");             var parameters = httputility.parsequerystring(string.empty);             parameters["email"] = maindatasource.createnavigator().selectsinglenode("/my:myfields/my:email", namespacemanager).value;             parameters["password"] = maindatasource.createnavigator().selectsinglenode("/my:myfields/my:password", namespacemanager).value;             parameters["device"] = maindatasource.createnavigator().selectsinglenode("/my:myfields/my:device", namespacemanager).value; ;             parameters["number"] = maindatasource.createnavigator().selectsinglenode("/my:myfields/my:mobilenumber", namespacemanager).value;             parameters["message"] = maindatasource.createnavigator().selectsinglenode("/my:myfields/my:sms_to_be_sent", namespacemanager).value; ;             uribuilder.query = parameters.tostring();             //uribuilder.fragment = "some_fragment";              uri finalurl = uribuilder.uri;             var request = webrequest.create(finalurl);              // response.             webresponse result = request.getresponse();                // stream containing content returned server.             stream datastream = result.getresponsestream();             // open stream using streamreader easy access.             streamreader reader = new streamreader(datastream);             // read content.             string responsefromserver = reader.readtoend();      dynamic stuff = jsonconvert.deserializeobject(responsefromserver); var result1 = stuff.result; var success1 = result1.success;   string value = convert.tostring(success1);                // display content.  system.windows.forms.messagebox.show(value);           }             // clean streams.             reader.close();             datastream.close();             result.close();           }     } 

here json example success

{ "success": true, "result": { "success": [ { "id": "308", "device_id": "4", "message": "hello world!", "status": "pending", "send_at": "1414624856", "queued_at": "0", "sent_at": "0", "delivered_at": "0", "expires_at": "1414634856", "canceled_at": "0", "failed_at": "0", "received_at": "0", "error": "none", "created_at": "1414624856", "contact": { "id": "14", "name": "phyllis turner", "number": "+447791064713" } } ], "fails": [ ] } } 

here json example failure

{ "success": true, "result": { "success": [ ], "fails": [ "number": "+44771232343" "message": "hello world!", "device": 1 "errors": { "device": ["the selected device invalid"], } ] } } 

all want if succeeds should able display part of json, example id, device id or message , if failure should able display part of json example device, number or errors.

updated failure response after stevej pointed:

   {     "success": true,     "result": {         "success": [],         "fails": [             {                 "email": "abc@xyz.com",                 "password": "anypassword",                 "device": 1,                 "number": "+44771232343",                 "message": "hello world!",                 "errors": {                     "device": [                         "the selected device invalid"                     ]                 }             }         ]     } } 

first: fail response give doesn't validate. paste jsonlint , see fails validation. perhaps copy/paste error - need straightened out. aside, here steps.

1. combine success , fail 1 json object (see example below)
2. paste json website such http://json2csharp.com/. give classes model json object (seem second example below)
3. uses newtonsoft's method, jsonconvert.deserializeobject(json) convert json string instance of rootobject class (rename class if like)
4. user newly created class other, no longer needing aware came web service.

example 1: modified json

    {     "success": true,     "result":      {         "success":          [             {                 "id": "308",                 "device_id": "4",                 "message": "hello world!",                 "status": "pending",                 "send_at": "1414624856",                 "queued_at": "0",                 "sent_at": "0",                 "delivered_at": "0",                 "expires_at": "1414634856",                 "canceled_at": "0",                 "failed_at": "0",                 "received_at": "0",                 "error": "none",                 "created_at": "1414624856",                 "contact":                  {                     "id": "14",                     "name": "phyllis turner",                     "number": "+447791064713"                 }             }         ],         "fails":          [             {                 "number": "+44771232343",                 "message": "hello world!",                 "device": 1,                 "errors":                  {                     "device": ["the selected device invalid"]                 }             }          ]     } } 

example 2 : list of classes needed

public class contact {     public string id { get; set; }     public string name { get; set; }     public string number { get; set; } }  public class success {     public string id { get; set; }     public string device_id { get; set; }     public string message { get; set; }     public string status { get; set; }     public string send_at { get; set; }     public string queued_at { get; set; }     public string sent_at { get; set; }     public string delivered_at { get; set; }     public string expires_at { get; set; }     public string canceled_at { get; set; }     public string failed_at { get; set; }     public string received_at { get; set; }     public string error { get; set; }     public string created_at { get; set; }     public contact contact { get; set; } }  public class errors {     public list<string> device { get; set; } }  public class fail {     public string number { get; set; }     public string message { get; set; }     public int device { get; set; }     public errors errors { get; set; } }  public class result {     public list<success> success { get; set; }     public list<fail> fails { get; set; } }  public class rootobject {     public bool success { get; set; }     public result result { get; set; } } 

usage

    static void main(string[] args)     {          var successjson = "{\"success\": true,\"result\": {\"success\": [{\"id\": \"308\",\"device_id\": \"4\"," +                           "\"message\": \"hello world!\",\"status\": \"pending\",\"send_at\": \"1414624856\", \"queued_at\": \"0\", " +                           "\"sent_at\": \"0\", \"delivered_at\": \"0\", \"expires_at\": \"1414634856\", \"canceled_at\": \"0\"," +                           "\"failed_at\": \"0\", \"received_at\": \"0\", \"error\": \"none\", \"created_at\": \"1414624856\"," +                           "\"contact\": {\"id\": \"14\", \"name\": \"phyllis turner\", \"number\": \"+447791064713\"} " +                           "}],\"fails\": []}}";          var successroot = jsonconvert.deserializeobject<rootobject>(successjson);          var issuccess = successroot.result.success != null && successroot.result.success.count > 0;         var isfail = successroot.result.fails != null && successroot.result.fails.count > 0;         var message = successroot.result.success.first().message;      }
