使用JsonResult时，定义JSON字段名 [英] Define JSON field names when using JsonResult

问题描述

我有我的ASP.Net应用MVC4返回JsonResult动作。我的数据属性设置为pre定义类的数组。我的问题是，我想用不同的属性名序列化。不管我用什么属性，对象序列化与pre定义的属性名称。我试过没有结果如下：

  [数据成员（NAME =iTotalRecords）]
[JsonProperty（属性名=iTotalRecords）]
公众诠释总记录{搞定;组; }
 

我知道iTotalRecords似乎很傻，但这个动作是用于支持jQuery插件，预计iTotalRecords而不是总记录。当然，我想用的名字，在我的code-背后意义。

什么串行用于解析JsonResult？有什么我能做的还是我必须重新思考返回JsonResult作为操作的结果？

解决方案

  

什么串行用于分析JsonResult？

<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.script.serialization.javascriptserializer.aspx\"相对=nofollow> 的JavaScriptSerializer 。

  

有什么我能做的还是我必须重新思考返回JsonResult作为操作的结果？

两种可能性浮现在脑海中：

• 定义视图模型，然后映射您的域模型视图模型


• 编写使用Json.NET或DataContractJsonSerializer并允许您控制序列化属性的名称自定义操作的结果。在<一个href=\"http://stackoverflow.com/questions/1302946/asp-net-mvc-controlling-serialization-of-property-names-with-jsonresult\">following问题说明了这一点。

I have an action that returns a JsonResult in my ASP.Net MVC4 application. I'm setting the Data property to an array of pre-defined classes. My issue is that I want to serialize with different property names. No matter what attributes I use, the object is serialized with the pre-defined property names. I've tried the following with no results:

[DataMember(Name = "iTotalRecords")]
[JsonProperty(PropertyName = "iTotalRecords")]
public int TotalRecords { get; set; }

I know "iTotalRecords" seems silly, but this action is for supporting a jQuery plugin that expects "iTotalRecords" and not "TotalRecords". Of course, I want to use names that make sense in my code-behind.

What serializer is used to parse JsonResult? Is there anything I can do or do I have to re-think returning JsonResult as an action result?

解决方案

What serializer is used to parse JsonResult?

JavaScriptSerializer.

Is there anything I can do or do I have to re-think returning JsonResult as an action result?

Two possibilities come to mind:

• define a view model and then map your domain model to the view model
• write a custom action result that uses Json.NET or DataContractJsonSerializer and which allow you to control the names of the serialized properties. The following question illustrates this.
