namespace getPropTest
{
    public class dologin
    {
        public static RootObject rootObject = new RootObject();

        public class RootObject
        {
            public string param { get; set; }
        }

        public void exec()
        {
            rootObject.param = "New_param";
        }
    }

    class Program
    {
        public static object getObject(string className)
        {
            Assembly assembly = Assembly.GetExecutingAssembly();
            assembly.GetTypes();
            object obj = assembly.CreateInstance("getPropTest." + className); 
            return obj;
        }

        public static bool execMethod(object obj, string methodName)
        {
            try
            {
                Type type = obj.GetType();
                MethodInfo methodinfo = type.GetMethod(methodName);
                methodinfo.Invoke(obj, null);
                return true;
            }
            catch (Exception ex)
            {
                return false;
            }
        }

        public static void getProperties(object obj, string memberName)
        {
            Type type = obj.GetType();

            if (memberName == "RootObject")
            {
                MemberInfo[] memberInfo = type.GetMember("rootObject");
                object sub_obj = memberInfo.GetValue(0);

                Console.WriteLine(sub_obj.ToString());//RootObject rootObject

                /*

                 * 如何獲取rootObject下的所有屬性，比如此處的param = "New_param"？？？

                 */
            }
        }

        static void Main(string[] args)
        {
            object obj = getObject("dologin");
            execMethod(obj, "exec");
            getProperties(obj, "RootObject");
        }
    }
}

已解決

         public static void getProperties(object obj, string memberName)
        {
            Type type = obj.GetType();
            FieldInfo field = null;

            if (memberName == "RootObject")
            {
                field = type.GetField("rootObject");
            }

            object _obj = field.GetValue(obj);
            Type _type = _obj.GetType();

            foreach (PropertyInfo propertyInfo in _type.GetProperties())
            {
                Console.WriteLine("{0}: {1}", propertyInfo.Name, propertyInfo.GetValue(_obj, null));
            }
        }
