c# - 使用 Json.net 仅将接口(interface)属性序列化为 JSON

Question

像这样一个简单的类/接口(interface)

public interface IThing
{
    string Name { get; set; }
}

public class Thing : IThing
{
    public int Id { get; set; }
    public string Name { get; set; }
}

如何获取只有“Name”属性(只有底层接口(interface)的属性)的JSON字符串？

实际上，当我这样做的时候:

var serialized = JsonConvert.SerializeObject((IThing)theObjToSerialize, Formatting.Indented);
Console.WriteLine(serialized);

我得到完整的对象作为 JSON(Id + 名称)；

我用的方法，

public class InterfaceContractResolver : DefaultContractResolver
{
    private readonly Type _InterfaceType;
    public InterfaceContractResolver (Type InterfaceType)
    {
        _InterfaceType = InterfaceType;
    }

    protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
    {
        //IList<JsonProperty> properties = base.CreateProperties(type, memberSerialization);
        IList<JsonProperty> properties = base.CreateProperties(_InterfaceType, memberSerialization);
        return properties;
    }
}

// To serialize do this:
var settings = new JsonSerializerSettings() {
     ContractResolver = new InterfaceContractResolver (typeof(IThing))
};
string json = JsonConvert.SerializeObject(theObjToSerialize, settings);
