你不需要使用 JsonConverterAttribute，只要保持你的模型干净并使用 CustomCreationConverter 代替，代码更简单:

You don't need to use JsonConverterAttribute, just keep your model clean and use CustomCreationConverter instead, the code is simpler:

public class SampleConverter : CustomCreationConverter<ISample>
{
    public override ISample Create(Type objectType)
    {
        return new Sample();
    }
}

那么:

var sz = JsonConvert.SerializeObject( sampleGroupInstance );
JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter());
