每个类型的自定义 Json.NET 序列化器设置

我正在使用 ApiController，它使用全局 HttpConfiguration 类来指定 JsonFormatter 设置。我可以非常轻松地全局设置序列化设置，如下所示：

config.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = PreserveReferencesHandling.Objects;

问题是并非所有设置都适用于我的项目中的所有类型。我想为执行多态序列化的特定类型指定自定义 TypeNameHandling 和 Binder 选项。

如何在宠物类型上或至少在每个 ApiController 的基础上指定 Json Formatter.Serialization 设置？

根据您上面的评论，以下是每个控制器配置的示例：

[MyControllerConfig]
public class ValuesController : ApiController

[AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)]
public class MyControllerConfigAttribute : Attribute, IControllerConfiguration
{
    public void Initialize(HttpControllerSettings controllerSettings, HttpControllerDescriptor controllerDescriptor)
    {
        //remove the existing Json formatter as this is the global formatter and changing any setting on it
        //would effect other controllers too.
        controllerSettings.Formatters.Remove(controllerSettings.Formatters.JsonFormatter);

        JsonMediaTypeFormatter formatter = new JsonMediaTypeFormatter();
        formatter.SerializerSettings.PreserveReferencesHandling = PreserveReferencesHandling.All;
        controllerSettings.Formatters.Insert(0, formatter);
    }
}
