如何省略get-only属性，只有当[JsonProperty]属性没有设置在它

我使用Json。Net在我的项目中。我需要找到一个解决方案，只有当属性[JsonProperty]未设置时，才能获得仅属性不序列化。

public class Example
{
    [JsonProperty]
    public string ThisPropertyHasToBeSerialized {get;}
    public string ThisPropertyHasToBeSkipped {get;}
}

我找到了它的部分答案:是否有一种方法可以忽略Json中的get-only属性?. NET不使用JsonIgnore属性?但是我想留下一个机会，以便在需要时序列化仅获取属性。我正在考虑实现它在CreateProperty函数像这样

public class CustomContractResolver : DefaultContractResolver
{
    public static readonly CustomContractResolver Instance = new CustomContractResolver();
    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
        JsonProperty property = base.CreateProperty(member, memberSerialization);
        if(property.Writable||????????????)return property;
        else ?????  
    }
}

是否有办法检查json属性是否设置在属性([JsonProperty])上，而不是[JsonIgnore] ?谢谢。

public class CustomContractResolver : DefaultContractResolver
{
    public static readonly CustomContractResolver Instance = new CustomContractResolver();
    protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
    {
        JsonProperty property = base.CreateProperty(member, memberSerialization);
        // Ignore get-only properties that do not have a [JsonProperty] attribute
        if (!property.Writable && member.GetCustomAttribute<JsonPropertyAttribute>() == null)
            property.Ignored = true;
        return property;
    }
}
