Parse jsonObject from android and get it in webservice vb.net

Question

I have resolved the problem,

I think my problem is I don't know how to get JSON in webservice .NET

I use android studio for parse JSON Object to my webservice, the JSON Array and JSON Object is working,

but I got a bad request (maybe because I can't get JSON in webservice?)

            JSONObject jsonObject = new JSONObject();
            jsonObject.put("horary", jsonArray);
            URL url = new URL("URL");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setConnectTimeout(4000);
            conn.setRequestProperty("Content-Type", "application/json");
            conn.setRequestProperty("Accept","application/json");
            conn.setDoOutput(true);
            DataOutputStream os = new DataOutputStream(conn.getOutputStream());
            os.writeBytes(URLEncoder.encode(jsonObject.toString(), "UTF-8"));
            os.flush();
            os.close();
            Log.d("json", conn.getResponseMessage());<- bad Request

Here is my code from webservice vb.net. I don't know how to get the JSON object

     <WebInvoke(ResponseFormat:=WebMessageFormat.Json, UriTemplate:="Change/")>
        Function HReceiver(horary As String) As String Implements IService.HReceiver

I suppose I get the JSON with (horary As String) and I try many ways to deserialize,

but it's not the point, because I suppose I can't get JSON

            Dim ser As JavaScriptSerializer = New JavaScriptSerializer()
            Dim horary As ArrayHorary
            Dim result As String
            Try
                Dim items = Newtonsoft.Json.JsonConvert.DeserializeObject(Of ArrayHorary())(horary)
                result = horary.ToString
            Catch ex As Exception
                result = ex.ToString
            End Try
            Return result
        End Function

        Public Class ArrayHorary
            Public Property id As String
            Public Property name As String
        End Class

Thanks for the time

------------I Resolved With

<OperationContract()>
    Function HReceiver(horary As Horar) As String

    <DataContract()>
Public Class Horar
    <DataMember()>
    Public Property horary As List(Of Horari)
End Class

    <DataContract()>
Public Class Horari
    <DataMember()>
    Public Property id As String
    <DataMember()>
    Public Property name As String

End Class

in Service

<WebInvoke(ResponseFormat:=WebMessageFormat.Json, UriTemplate:="Change/")>
    Function HReceiver(horar As Horar) As String Implements IService.HReceiver
        Dim result As String

        result = horar.horary(0).name
return result

and this work without deserializer

in android, I must use

os.writeChars(URLEncoder.encode(jsonObject.toString(), "UTF-8"));

To recive a JSON object in a proper way you have to have a class with the same structure as a function parameter, for example if you are receiving a list of this object you api parameter should be:

Function SpoolsList(objVar As List(Of ArrayHorary)) As IHttpActionResult
    Your code
End Function

Then it will parse the object automatically.
