Json.Net解析属性名称正确 [英] Json.Net Resolving Property Names Properly

问题描述

我得到的一些数据，看起来像下面的JSON从API

I am getting some data that looks like below JSON from an API

{
    body_html: "<h1>Test</h1>",
    id: "cu1bpkz",
    link_id: "d3_3kkgis",
    author: "jdoe",
    author_flair_text: null,
    author_flair_css_class: null,
    parent_id: "t3_3kkgis",
    body: "Test",
    subreddit_id: "q5_39vkz",
    created_utc: 1442108087,
    subreddit: "test"
}

这是我的强类型类，我使用的反序列化：

And here is my Strongly-typed class that I use for deserialization:

public class Comment
{
    public string AuthorFlairText { get; set; }
    public string AuthorFlairCssClass { get; set; }
    public string Author { get; set; }
    public string LinkId { get; set; }
    public string Id { get; set; }
    public string BodyHtml { get; set; }
    public string Url { get; set; }
    public string SubredditId { get; set; }
    public string Subreddit { get; set; }
    public long CreatedUtc { get; set; }
    public string Body { get; set; }
    public string ParentId { get; set; }
}

这是我解决的属性名称解析：

This is my resolver for resolving the property names:

public class ApiContractResolver : DefaultContractResolver
    {
        protected override string ResolvePropertyName(string propertyName)
        {
            var parts = propertyName.Split(new string[] { "_" }, StringSplitOptions.RemoveEmptyEntries);
            return parts.Select(x => char.ToUpper(x[0]) + x.Substring(1)).Aggregate((curr, next) => curr + next);
        }
    }

这是我如何反序列化我的JSON，它不。工作

This is how I deserializing my JSON and it does not work.

var settings = new JsonSerializerSettings { ContractResolver = new ApiContractResolver() };
var obj = JsonConvert.DeserializeObject<Comment>(json, settings);

虽然像的身体和id的简单属性得到正确转换，更复杂的特性与_在道具名称做不。我缺少什么？

While simple properties like body and id get properly converted, more complex properties with _ in the prop name do not. What am I missing?

推荐答案

您可以试试这个。您可以使用 JsonPropertyAttribute 来告诉Json.Net属性所对应的JSON领域是什么。​​

You can try this. you can use JsonPropertyAttribute to tell Json.Net what the property's corresponding json field is.

public class Comment
{
    [JsonProperty("author_flair_text")]
    public string AuthorFlairText { get; set; }

    [JsonProperty("author_flair_css_class")]
    public string AuthorFlairCssClass { get; set; }

    [JsonProperty("author")]
    public string Author { get; set; }

    [JsonProperty("link_id")]
    public string LinkId { get; set; }

    [JsonProperty("id")]
    public string Id { get; set; }

    [JsonProperty("body_html")]
    public string BodyHtml { get; set; }

    [JsonProperty("url")]
    public string Url { get; set; }

    [JsonProperty("subreddit_id")]
    public string SubredditId { get; set; }

    [JsonProperty("subreddit")]
    public string Subreddit { get; set; }

    [JsonProperty("created_utc")]
    public long CreatedUtc { get; set; }

    [JsonProperty("body")]
    public string Body { get; set; }

    [JsonProperty("parent_id")]
    public string ParentId { get; set; }
}

别的

一切都被照顾唯一的网址是我不能在JSON找物业。请看看别人的代码是准备好复制粘贴和运行。

Everything else has been taken care only URL is the property which I cannot find in the JSON. Please have a look else the code is ready to get copy paste and run.

您可以存储类型的对象 JsonModel ，并在模型的构造使用初始化 JsonConvert.DeserializeObject< T> 。你的公共属性，则可以只叫成 JsonModel 实例，并得到相应的值。

you could store an object of type JsonModel and in your model's constructor initialize it using JsonConvert.DeserializeObject<T>. Your public properties could then just call into that JsonModel instance and get the appropriate values.
