如何使用JsonConverter仅序列化类的继承属性

如何使用JsonConverter仅序列化类的继承属性

不知道为什么您的代码不起作用（可能是Json.NET错误？）。相反，您可以从中删除不需要的属性，

JObject

并在一个调用中编写整个内容：

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)    {        // Find properties of inherited class        var classType = value.GetType();        var classProps = classType.GetProperties(BindingFlags.Declaredonly | BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic).ToList();        // Remove the overrided properties        classProps.RemoveAll(t =>        { var getMethod = t.GetGetMethod(false); return (getMethod.GetbaseDefinition() != getMethod);        });        // Get json data        var o = (JObject)JToken.FromObject(value);        // Remove all base properties        foreach (var p in o.Properties().Where(p => !classProps.Select(t => t.Name).Contains(p.Name)).ToList()) p.Remove();        o.WriteTo(writer);    }

另外，您可以创建自己的合同解析器并过滤基本属性和成员：

public class EverythingButbaseContractResolver : DefaultContractResolver{    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)    {        if (member.ReflectedType != member.DeclaringType) return null;        if (member is PropertyInfo)        { var getMethod = ((PropertyInfo)member).GetGetMethod(false); if (getMethod.GetbaseDefinition() != getMethod)     return null;        }        var property = base.CreateProperty(member, memberSerialization);        return property;    }}

然后像这样使用它：

        var settings = new JsonSerializerSettings { ContractResolver = new EverythingButbaseContractResolver() };        var json = JsonConvert.SerializeObject(rootObject, Formatting.Indented, settings);
