How to serialize an object in windows phone 7

Question

How to convert an object to JSON data in windows phone. In web application I have used following code

 JavaScriptSerializer serializer = new JavaScriptSerializer();
 string stringData = serializer.Serialize(object);

I want to get the same output as that of the above code in windows phone 7.

Answer 1

JavaScriptSerializer is not supported on Windows Phone. An alternative is to use JSON.NET (you can add it via NuGet).

The code will then look like this:

string stringData = JsonConvert.SerializeObject(object);

firrst you need to download Newtonsoft.Json dll for parse web serevice

Just follow bellow step

Step1: Add Service References by right click on add References.

Step2: Now put your web service link on Service References and press go button, And also add Namespace of service Reference

Step3: Now add using Newtonsoft.Json.Linq; name space in your .cs file

Step4: Now add bellow code in your cs file

 WhatsupServices.WhatsUpServiceSoapClient ws = new WhatsupServices.WhatsUpServiceSoapClient();
ws.ContactUsJSONCompleted += ws_ContactUsJSONCompleted;
ws.ContactUsJSONAsync(txtContactUsName.Text, txtContactUsPhone.Text, txtContactUsEmail.Text, txtContactUsComment.Text);

step6: now genrate your resopnce method

 void ws_ContactUsJSONCompleted(object sender, dynamic e)
        {
            if (e.Error != null)
            {
                MessageBox.Show(LogIn.NetworkBusyMsg, LogIn.MsgHdr, MessageBoxButton.OK);
                busyIndicator.IsRunning = false;
            }
            else
            {
                busyIndicator.IsRunning = false;
                string Result = e.Result;
                JObject obj = JObject.Parse(Result);
                string ResultCode = (string)obj["ResultCode"];
                string ResponceMessage = (string)obj["ResponseMessage"];

                if (ResultCode == "1")
                {
                    MessageBox.Show("Thank you for your message. We'll get back to you soon.", LogIn.MsgHdr, MessageBoxButton.OK);
                    NavigationService.GoBack();
                }
                else
                {
