JsonIgnore在System.Web.Mvc.Controller中不起作用 [英] JsonIgnore not working in System.Web.Mvc.Controller

问题描述

我有一个Web-API项目和一个带有一些属性的简单类，其中一些标记为<JsonIgnore>.

I have a web-API project and a simple class with a few properties, some are marked <JsonIgnore>.

在我的MVC控制器中，放入Return Json(instanceOfMyClass, JsonRequestBehavior.AllowGet).所有成员都已序列化. 我在我的WEBAPI控制器中放入了Return Json(Of MyClass)(instanceOfMyClass).仅存在我要序列化的成员.

In my MVC-controller I put Return Json(instanceOfMyClass, JsonRequestBehavior.AllowGet). All members are serialized. I put Return Json(Of MyClass)(instanceOfMyClass) in my WEBAPI-controller. Only the members I intend to serialize are present.

如何独立于将要序列化的控制器而忽略这些属性.

How can I ignore these properties independent of the controller that's going to serialize.

推荐答案

MVC中的JsonResult实际上并未使用JSON.NET，这就是[JsonIgnore]无法正常工作的原因.而是使用JavaScriptSerializer类.

The JsonResult in MVC does not actually use JSON.NET which is why [JsonIgnore] is not working. Instead it uses the JavaScriptSerializer class.

要使JavaScriptSerializer跳过属性，可以在模型属性上使用[ScriptIgnore]属性.

To make the JavaScriptSerializer skip a property, you can you the [ScriptIgnore] attribute on your model property.

另一种选择是使用JSON.NET的JsonConvert创建自定义ActionResult来序列化对象，然后使用[JsonIgnore]属性.

An alternative would be to make a custom ActionResult that uses JSON.NET's JsonConvert to serialize the object which would then honor the [JsonIgnore] attribute.
