Slight modification on @JRodd version to support objects coming from Json (JObject)

public static dynamic ToDynamic(this object value)
    {
        IDictionary expando = new ExpandoObject();

        //Get the type of object 
        Type t = value.GetType();

        //If is Dynamic Expando object
        if (t.Equals(typeof(ExpandoObject)))
        {
            foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(value.GetType()))
                expando.Add(property.Name, property.GetValue(value));
        }
        //If coming from Json object
        else if (t.Equals(typeof(JObject)))
        {
            foreach (JProperty property in (JToken)value)
                expando.Add(property.Name, property.Value);
        }
        else //Try converting a regular object
        {
            string str = JsonConvert.SerializeObject(value);
            ExpandoObject obj = JsonConvert.DeserializeObject(str);

            return obj;
        }

       

        return expando as ExpandoObject;
    }
