ServiceStack.Text和Twitter JSON

时间：2013-09-30 15:08:00

标签： c# servicestack deserialization servicestack-text

我正在尝试使用ServiceStack.Text对twitter RateLimit Json进行反序列化。我创建了一个适当的DTO对象（查看帖子的底部），以便将JSON拉下来。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对象中使用过它）。反序列化对象时，RateLimitContext正确反序列化，但是Resources下的所有项目反序列化为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中的错误还是我在DTO中遗漏了什么？
