只有在Json.Net中没有显式设置PropertyName时才使用CamelCase？
我在我的网站上使用Json.Net。 我希望序列化程序默认在camelcase中序列化属性名称。 我不希望它更改我手动分配的属性名称。 我有以下代码：
public class TestClass { public string NormalProperty { get; set; } [JsonProperty(PropertyName = "CustomName")] public string ConfiguredProperty { get; set; } } public void Experiment() { var data = new TestClass { NormalProperty = null, ConfiguredProperty = null }; var result = JsonConvert.SerializeObject(data, Formatting.None, new JsonSerializerSettings {ContractResolver = new CamelCasePropertyNamesContractResolver()} ); Console.Write(result); } Experiment的输出是：
{"normalProperty":null,"customName":null}
但是，我希望输出为：
{"normalProperty":null,"CustomName":null}
这有可能实现吗？
您可以像这样覆盖CamelCasePropertyNamesContractResolver类：
class CamelCase : CamelCasePropertyNamesContractResolver { protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization) { var res = base.CreateProperty(member, memberSerialization); var attrs = member .GetCustomAttributes(typeof(JsonPropertyAttribute),true); if (attrs.Any()) { var attr = (attrs[0] as JsonPropertyAttribute); if (res.PropertyName != null) res.PropertyName = attr.PropertyName; } return res; } }
随着NamingStrategy的推出，它变得更容易。
作为奖励，你可以让它不修改字典键。
class MyContractResolver : CamelCasePropertyNamesContractResolver { public MyContractResolver() { NamingStrategy.OverrideSpecifiedNames = false; //Overriden NamingStrategy.ProcessDictionaryKeys = false; //Overriden NamingStrategy.ProcessExtensionDataNames = false; //default } }
