c# - ServiceStack.Text 和 Twitter JSON

Question

我正在尝试使用 ServiceStack.Text 反序列化 twitter RateLimit Json。我为下拉的 JSON 创建了一个适当的 DTO 对象(查看帖子底部)。我利用 System.Runtime.Serialization 将字段重命名为更友好的名称(我在 Twitter 的许多其他 DTO 对象中使用了它)。反序列化对象时，RateLimitContext 正确反序列化，但 Resources 下的所有项目都反序列化为 null。我怀疑这个特定对象的 DataMemberNames 有问题，因为它们包含几个“特殊”字符。这是 ServiceStack.Text 中的错误还是我的 DTO 中遗漏了什么？
