That’s why I found myself unwilling to add dumb C# POCO objects just to handle JSON serialization and deserialization in the SignalR hub(s), and I turned to dynamic objects and Json.Net (starting from version 4.0) to handle this tasks easily and quickly.
Let’s say that for example I want to send data to the browser. All I have to do is to create an ExpandoObject (my new favourite .Net class!) and serialize it using Json.Net “JsonConvert.SerializeObject()”.
Let’s see an example:
dynamic foo = new ExpandoObject(); foo.Bar = "something"; string json = Newtonsoft.Json.JsonConvert.SerializeObject(foo);
And here is the output:
Json.Net offers a great way to deserialize a JSON string into a dynamic using the JObject (you can find it under the Newtonsoft.Json.Linq namespace and here the details).
Let’s see an example re-using the previous foo object:
dynamic foo = JObject.Parse(jsonText); string bar = foo.Bar; // bar = "something"
And that’s it, really easy and yet really powerful.
In a more structured application, I would probably not use this trick as I would probably have all of my ViewModels and Domain Models objects ready to use in type safe serialization/deserialization operations, but that’s not always the case.
I hope this helps.
