C# flattening json structure

Question

I have a json-object in C# (represented as a Newtonsoft.Json.Linq.JObject object) and I need to flatten it to a dictionary. Let me show you an example of what I mean:

You can use https://github.com/jsonfx/jsonfx to deserialize json into a dynamic object. Then use the ExpandoObject to get what you want.

public Class1()
        {
            string json = @"{
                                ""name"": ""test"",
                                ""father"": {
                                     ""name"": ""test2"",
                                     ""age"": 13,
                                     ""dog"": {
                                         ""color"": ""brown""
                                     }
                                }
                            }";

            var reader = new JsonFx.Json.JsonReader();
            dynamic output = reader.Read(json);
            Dictionary dict = new Dictionary();

            GenerateDictionary((System.Dynamic.ExpandoObject) output, dict, "");
        }

        private void GenerateDictionary(System.Dynamic.ExpandoObject output, Dictionary dict, string parent)
        {
            foreach (var v in output)
            {
                string key = parent + v.Key;
                object o = v.Value;

                if (o.GetType() == typeof(System.Dynamic.ExpandoObject))
                {
                    GenerateDictionary((System.Dynamic.ExpandoObject)o, dict, key + ".");
                }
                else
                {
                    if (!dict.ContainsKey(key))
                    {
                        dict.Add(key, o);
                    }
                }
            }
        }
