Razor without mvc part iii support for nested anonymous types

One of the problems with my previous post was you couldn’t have an object definition like:

var nestedType = new {
    Name = "Ben",
    Accounts = new {
        Twitter = "BuildStarted",
        StackOverflow = "BuildStarted"
    }
};

I’ve updated the RazorDynamicObject to compensate.

/// <summary>
/// Dynamic object that we'll utilize to return anonymous type parameters
/// </summary>
class RazorDynamicObject : DynamicObject {
    internal object Model { get; set; }
    public override bool TryGetMember(GetMemberBinder binder, out object result) {
        PropertyInfo propInfo = Model.GetType().GetProperty(binder.Name);

        if (propInfo == null) {
            throw new InvalidOperationException(binder.Name);
        }

        object returnObject = propInfo.GetValue(Model, null);

        Type modelType = returnObject.GetType();
        if (modelType != null
            && !modelType.IsPublic
            && modelType.BaseType == typeof(Object) 
            && modelType.DeclaringType == null) {
                result = new RazorDynamicObject() { Model = returnObject };
        } else {
            result = returnObject;
        }

        return true;
    }
}

Now, we’re checking to see if the object we’re pulling out of our model is another anonymous type and returning a new RazorDynamicObject to handle subsequent anonymous type calls.

I probably could have used the ExpandoObject but this works just fine.
