javascriptserializer

I'm successfully using the JavaScriptSerializer in MVC3 to de-serialize a json string in to a dynamic object. What I can't figure out is how to cast it to something I can enumerate over. The foreach line of code below is my latest attemt but it errors with: "Cannot implicitly convert type 'System.Dynamic.DynamicObject' to 'System.Collections.IEnumerable'.

Reading Can I set an unlimited length for maxJsonLength in web.config I put the jsonSerialization maxJsonLength key in my web.config but it gets ignored. Though I can set the JavaScriptSerializer.MaxJsonLength property in code and it works fine. I would like to have the value in the Web.config rather than code. Here

Trying to create a service to return an object that has many shared properties, but one property should be highly limited in some situations. This is resulting in odd and undesired behaviour, where a property name is reused in the serialized output, resulting in incorrect behaviour in the browser. Here is an example that can be pasted into LINQPad (if you add a reference to System.Web.Extensions ) to see the problem: void Main() { System.Web.Script.Serialization.JavaScriptSerializer json = new System.Web.Script.Serialization.JavaScriptSerializer(); json.Serialize(new Full(true)).Dump(); json
