Pass json string data to Rest service (POST Method) using c#

Hi guys,

  In my project i have to pass dynamic Json string to WCF Rest service. Here both Input / Output should be in Json format. I am using server side code to pass my data. Here is my code 

In testpage.aspx.cs Page

------------------------

    string json = "{\"sjSonData\":[{"

                             + "\"log_Id\" : 0,"

                             + "\"user_Id\" : 1249,"

                             + "\"session_key\" : \"dvnoewcdw\","

                             + "\"app_id\" : 1,"

                             + "\"app_version\" :\"1.2.7\","

                             + "\"app_isOnline\" : true,"

                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\","

                             + "\"log_typeId\" : 1,"

                             + "\"log_description\" : \"valid\""

                         + "},"

                         + "{"

                             + "\"log_Id\" : 1,"

                             + "\"user_Id\" : 1249,"

                             + "\"session_key\" : \"dvnoewcdw\","

                             + "\"app_id\" : 1,"

                             + "\"app_version\" : \"1.2.7\","

                             + "\"app_isOnline\" : true,"

                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\""

                             +"}]}";

    

    const string url = "http://localhost/RestServiceImpl.svc/jsoninputdata";

  

           //create an HTTP request to the URL that we need to invoke

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

                //request.ContentLength = byteArray.Length;

                request.ContentType = "application/json; charset=utf-8"; //set the content type to JSON

                request.Method = "POST"; //make an HTTP POST

                using (var streamWriter = new StreamWriter(request.GetRequestStream()))

                {

                    //initiate the request

                    JavaScriptSerializer serializer = new JavaScriptSerializer();

                    var resToWrite = serializer.Deserialize>(json);

                    streamWriter.Write(restoWrite);

                    streamWriter.Flush();

                    streamWriter.Close();

                }

                // Get the response.

                WebResponse response = request.GetResponse();                

                var streamReader = new StreamReader(response.GetResponseStream());                

                var result = streamReader.ReadToEnd();

I am new to WCF service. I don't know how to pass this data to Rest service. Here my input data has been differed every call. 

Rest Service code

-------------------

[ServiceContract]

 public interface IRestServiceImpl

 {

   [OperationContract]

        [WebInvoke(Method = "POST",

            ResponseFormat = WebMessageFormat.Json,

            RequestFormat = WebMessageFormat.Json,

            BodyStyle = WebMessageBodyStyle.Bare,

            UriTemplate = "jsoninputdata")]

    string jsoninputdata(List> rData);

 }

 public class RestServiceImpl : IRestServiceImpl

 {

      public jSonResponseData jsoninputdata(List> rData)

      {   

          string json = JsonConvert.SerializeObject(rData);         

          

          //Do my stuff here.....

          return ojSonRes; // Here i need to return my output mentioned below

      }

  }

And i need to return data (output) like below,

**Condition 1:** If both saved in db without any error,

{"sjSonData":[{

  "success":true

}]}

**Condition 2:** Suppose any one data failed to save in database then

{"sjSonData":[

{

"log_Id":1,

"success":false

},

{

 "log_Id":2,

 "success":true

}

]}

Now I am getting result like,

{"sjSonData":"{}"}

Am i doing anything wrong,and also please explain what are all changes i have to do in web.config file.
