DefaultContractResolver.CreateProperty返回的JsonProperty类有两个转换器,Converter和MemberConverter的属性.我没有找到足够的解释,所以有什么区别呢？何时使用每一个？在合同解析器中设定什么属性？从
official documentation获取或设置成员转换器是没有帮助的.
NS.Json似乎支持可以覆盖的转换器;大概这是为了使每个单独的属性不必指定一个JsonConverter,但如果需要,它们可以覆盖它.
原文链接：https://www.f2er.com/json/288450.html在源中可以找到提示：
从DefaultContractResolver.cs,行1254：
private void SetPropertySettingsFromAttributes(JsonProperty property,object attributeProvider,string name,Type declaringType,MemberSerialization memberSerialization,out bool allowNonPublicAccess)
{
...
// resolve converter for property
// the class type might have a converter but the property converter takes presidence
property.Converter = JsonTypeReflector.GetJsonConverter(attributeProvider);
property.MemberConverter = JsonTypeReflector.GetJsonConverter(attributeProvider);
并从JsonSerializerInternalReader.cs,line 348：
private JsonConverter GetConverter(JsonContract contract,JsonConverter memberConverter,JsonContainerContract containerContract,JsonProperty containerProperty)
{
JsonConverter converter = null;
if (memberConverter != null)
{
// member attribute converter
converter = memberConverter;
}
else if (containerProperty != null && containerProperty.ItemConverter != null)
{
converter = containerProperty.ItemConverter;
}
else if (containerContract != null && containerContract.ItemConverter != null)
{
converter = containerContract.ItemConverter;
}
else if (contract != null)
{
JsonConverter matchingConverter;
if (contract.Converter != null)
// class attribute converter
converter = contract.Converter;
else if ((matchingConverter = Serializer.GetMatchingConverter(contract.UnderlyingType)) != null)
// passed in converters
converter = matchingConverter;
else if (contract.InternalConverter != null)
// internally specified converter
converter = contract.InternalConverter;
}
return converter;
}
