使用JSON.net获取JToken的名称/密钥

问题描述

我有一些看起来像这样的JSON

I have some JSON that looks like this

[
  {
    "MobileSiteContent": {
      "Culture": "en_au",
      "Key": [
        "NameOfKey1"
      ]
    }
  },
  {
    "PageContent": {
      "Culture": "en_au",
      "Page": [
        "about-us/"
      ]
    }
  }
]

我将其解析为JArray:

I parse this as a JArray:

var array = JArray.Parse(json);

然后，我遍历数组:

foreach (var content in array)
{

}

content是JToken

如何检索每个项目的名称"或键"?

How can I retrieve the "name" or "key" of each item?

例如"MobileSiteContent"或"PageContent"

For example, "MobileSiteContent" or "PageContent"

推荐答案

JToken是JObject，JArray，JProperty，JValue等的基类.可以使用Children<T>()方法，以获取具有特定类型(例如JObject)的JToken子级的过滤列表.每个JObject都有一个JProperty对象的集合，可以通过Properties()方法进行访问.对于每个JProperty，您都可以获取其Name. (当然，如果需要，您还可以获取Value，这是另一个JToken.)

JToken is the base class for JObject, JArray, JProperty, JValue, etc. You can use the Children<T>() method to get a filtered list of a JToken's children that are of a certain type, for example JObject. Each JObject has a collection of JProperty objects, which can be accessed via the Properties() method. For each JProperty, you can get its Name. (Of course you can also get the Value if desired, which is another JToken.)

将所有内容放在一起:

JArray array = JArray.Parse(json);

foreach (JObject content in array.Children<JObject>())
{
    foreach (JProperty prop in content.Properties())
    {
        Console.WriteLine(prop.Name);
    }
}

输出:

MobileSiteContent
PageContent
