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

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

Then you'd be better off using dynamic I'd say

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);
        }
