JSObject error in c# reflection

Question

hello,
I'm using c# and Javascript object to do some pdf manipulation. Please see the below code, I ran into an "Unknown Name" error at the last line when trying to get the "children" object from the BookmarkRoot. Getting the "name" and "color" worked fine, but I don't know why I'm getting the "unknown name" error for the "children". Am I missing something? any suggestions?
object jsObj = pdfFinal.GetJSObject();
object bmr = jsObj.GetType().InvokeMember(
            "bookmarkRoot",
            System.Reflection.BindingFlags.GetProperty,
            null, jsObj, null);
object name = bmr.GetType().InvokeMember("name",
            System.Reflection.BindingFlags.GetProperty,
            null,bmr,null);
object color = bmr.GetType().InvokeMember("color",
            System.Reflection.BindingFlags.GetProperty,
            null, bmr, null);
//the below line gives Unknown name. (Exception from HRESULT: 0x80020006(DISP_E_UNKNOWNNAME))
object children = bmr.GetType().InvokeMember("children",
            System.Reflection.BindingFlags.GetProperty,
            null, bmr, null);
Thanks,
John

Use:
Array children = (Array)bmr.GetType() ....
