        {          
            string myJsonString = @"{'PhotoName':'mypic.jpg','IsModerated':'false'}";

            //From Json String to C# Object
            MemberPics cSharpObj = JsonConvert.DeserializeObject(myJsonString);         
            Console.WriteLine("Photo Name: " + cSharpObj.PhotoName + ",  IsModerated: " + cSharpObj.IsModerated);


            //From C# Object to Json String
            string jsonString = JsonConvert.SerializeObject(cSharpObj, Formatting.Indented);
            Console.WriteLine(jsonString);

            Console.WriteLine("Press any key to exit");
            Console.ReadLine();
