Applying a Contract Resolver to a specific model via an attribute

由 ぃ、小莉子 提交于 2019-12-25 09:45:21
问题 I am using Web API which internally uses Json.Net. Currently, I have a scenario where I need to apply a custom contract resolver only to one specific model. I can apply a custom JsonConverter using an attribute like [JsonConverter(typeof(MyConverter))] . Is it possible to apply a custom contract resolver on one model in the same way? In my scenario, I need to be able to use [JsonProperty] attributes during deserialization but ignore them during serialization, just for one of my model classes.

The first few times I tested this, I discovered that this property was always null, but the strange part is that if you checked the HttpRequestMessage.Headers enumerable, the
