问题描述

基于迭戈在此问题中投票最高的答案下未得到回答的评论:

Based on Diego's unanswered comment under the top-voted answer in this question:

对于一个枚举:

public enum ContactType
{
    Phone = 0,
    Email = 1,
    Mobile = 2
}

例如属性:

//could contain ContactType.Phone, ContactType.Email, ContactType.Mobile
IEnumerable<ContactType> AvailableContactTypes {get;set;}

对于类似JSON的内容:

To something like the JSON:

{ContactTypes : ['Phone','Email','Mobile']}

代替

{ContactTypes : [0,1,2]}

与普通的JavaScriptSerializer一样吗?

As is the case with the normal JavaScriptSerializer?

推荐答案

似乎在Json.NET的更高版本之一中，通过 ItemConverterType 属性/html/T_Newtonsoft_Json_JsonPropertyAttribute.htm"rel =" nofollow noreferrer> JsonProperty 属性，如此处所述:

It would appear that in one of the later versions of Json.NET there is proper provision for this, via the ItemConverterType property of the JsonProperty attribute, as documented here:

当我遇到从Json.NET 3.5升级与我自己的项目相关的问题时，我无法尝试.最后，根据Shmiddty的建议，我将视图模型转换为IEnumerable<string>(尽管仍然存在阻抗不匹配，以后我会重新重构它).

I was unable to try it out as I hit problems upgrading from Json.NET 3.5 that were related to my own project. In the end I converted my viewmodel to IEnumerable<string> as per Shmiddty's suggestion (there is still an impedance mismatch though and I will come back to refactor this in future).

希望对其他遇到相同问题的人有所帮助！

Hope that helps anyone else with the same problem!

示例用法:

[JsonProperty(ItemConverterType = typeof(StringEnumConverter))]
IEnumerable<ContactType> AvailableContactTypes {get;set;}
