只是试图找出如何servicestack.text支持序列化的expando对象和JSON。 我知道，在Expando对象实现了一个IDictionary。 当我序列化和JSON我无法得到正确的类型在反序列化的IDictionary。 为JSON不支持原生类型和servicestack有一个名为JsConfig.IncludeTypeInfo我预计它包括在序列化JSON类型的信息，以使服务栈反序列化到正确类型的另一侧，设置（例如无小数位小数反序列化到一个UINT64）。
反正是有强制servicestack正确的反序列化类型相同使用的expando对象的来源？
PS：我不想使用POCO对象来实现这个，因为我不知道该对象的属性，直到运行时。
下面是一个快速测试显示我的意思。
谢谢
