New Post: JSonObject IEnumerable?

I have a json string which contains an array of dictionaries for a TreeView. However the following won't compile as IJSonObject can't be converted to System.Collections.IEnumerable. Can IJSonObject be modified to support this case?

s = @"[{""title"":""Title1"",""children"":[{""title"":""Child1"",""children"":[{""title"":""grandchild1"",""children"":[{""title"":""Huh""}]}] }] }]";

JSonReader jr = new JSonReader();
IJSonObject json = jr.ReadAsJSonObject(str);
mTreeView.ItemsSource = json;
