Deserialize JSON string to Object C# using Json.NET

Question

I want to deserialize a JSON string that I don't know its Type to an object of type Object and be able to access its properties using reflection. when I used this

object myObject = JsonConvert.DeserializeObject("{\'Id\':\'1\'}");

the type of myObject is of type JObjectand I am not able to access its properties using reflection.

is there a way to do so using Json.net or any other JSON deserializer?

@scotru I've tried the dynamic too. My point is that I need to access its properties using reflection. the generated dynamic object is also of type JObject — Heba Gomaah, Dec 11 '16 at 08:40
Your question should be answered under this link: [JSON deserialize](http://stackoverflow.com/questions/35238194/deserialize-json-with-json-net-into-c-sharp-dynamic) — Moerwald, Dec 11 '16 at 08:40

Hmm, still not following the difficulty here--is the question how to use reflection on dynamic objects? If so see http://stackoverflow.com/questions/8631546/get-property-value-from-c-sharp-dynamic-object-by-string-reflection — scotru, Dec 11 '16 at 08:57
@HebaGomaah have you tried to create an object that contains all properties — BRAHIM Kamel, Dec 11 '16 at 08:59
@scotru the question is, is there any deserializer that can convert a json string to an object just as if the type of the data is a predefined type? not to a JObject — Heba Gomaah, Dec 11 '16 at 09:25
@HebaGomaah I understand now. Is the Json simple (attribute value pairs?) If so I think grrrrrs answer is best. If not maybe you could use an ExpandoObject as described here: http://stackoverflow.com/questions/22906010/deserialize-dynamic-json-string-using-newtonsoft-json-net AND https://stackoverflow.com/questions/2594527/how-do-i-iterate-over-the-properties-of-an-anonymous-object-in-c — scotru, Dec 11 '16 at 09:35

I think you can deserialize the object into either a Dictionary<string,string> or an expandoobject (also castable to IDictionary<string,object>) and then you don't need to use reflection to get at the properties, you can get them through the dictionary.

{"Id":"1"} is just a sample. The properties can be of any type, may be of a new object – Heba Gomaah Dec 11 '16 at 09:21
Then you'd be better off using dynamic I'd say – gmn Dec 11 '16 at 09:22

This doesn't let you use reflection per-se but an ExpandoObject does let you iterate over the properties:

        string json = "{\'Id\':\'1\'}";
        var converter = new ExpandoObjectConverter();
        dynamic obj = JsonConvert.DeserializeObject<ExpandoObject>(json, converter);

        IDictionary<string, object> dict = (IDictionary<string, object>)obj;
        foreach (string key in dict.Keys)
        {
            Console.WriteLine(key);
        }
