遍历JSON对象在C＃ [英] Iterating over JSON object in C#

问题描述

我在C＃中使用JSON.NET解析来自API的Klout的响应。我的回答是这样的：

  [
  {
    ID：5241585099662481339
    显示名：音乐，
    名：音乐，
    弹头：音乐，
    图片网址：http://kcdn3.klout.com/static/images/music-1333561300502.png
  }，
  {

  }
]
 

正如你所见，它包含5 ID 标记。也许下一次将是6或1或其他一些数字。我想遍历JSON和获得每个 ID 标记的值。我无法不知道有多少会运行一个循环。我怎样才能解决这个问题？

解决方案

 动态dynJson = JsonConvert.DeserializeObject（JSON）;
的foreach（在dynJson VAR项）
{
    Console.WriteLine（{0} {1} {2} {3} \\ n，item.id，item.displayName，
        item.slug，item.imageUrl）;
}
 

或

  VAR列表= JsonConvert.DeserializeObject＆LT;名单，LT; MyItem＆GT;＆GT;（JSON）;公共类MyItem
{
    公共字符串ID;
    公共字符串显示名;
    公共字符串名称;
    公共字符串蛞蝓;
    公共字符串图片网址;
}
 

I am using JSON.NET in C# to parse a response from the Klout API. My response is like this:

[
  {
    "id": "5241585099662481339",
    "displayName": "Music",
    "name": "music",
    "slug": "music",
    "imageUrl": "http://kcdn3.klout.com/static/images/music-1333561300502.png"
  },
  {
    "id": "6953585193220490118",
    "displayName": "Celebrities",
    "name": "celebrities",
    "slug": "celebrities",
    "imageUrl": "http://kcdn3.klout.com/static/images/topics/celebrities_b32741b6703151cc7bd85fba24c44c52.png"
  },
  {
    "id": "5757029936226020304",
    "displayName": "Entertainment",
    "name": "entertainment",
    "slug": "entertainment",
    "imageUrl": "http://kcdn3.klout.com/static/images/topics/Entertainment_7002e5d2316e85a2ff004fafa017ff44.png"
  },
  {
    "id": "3718",
    "displayName": "Saturday Night Live",
    "name": "saturday night live",
    "slug": "saturday-night-live",
    "imageUrl": "http://kcdn3.klout.com/static/images/icons/generic-topic.png"
  },
  {
    "id": "8113008320053776960",
    "displayName": "Hollywood",
    "name": "hollywood",
    "slug": "hollywood",
    "imageUrl": "http://kcdn3.klout.com/static/images/topics/hollywood_9eccd1f7f83f067cb9aa2b491cd461f3.png"
  }
]

As you see, it contains 5 id tags. Maybe next time it would be 6 or 1 or some other number. I want to iterate over the JSON and get the value of each id tag. I can't run a loop without knowing how many there will be. How can I solve this?

解决方案

dynamic dynJson = JsonConvert.DeserializeObject(json);
foreach (var item in dynJson)
{
    Console.WriteLine("{0} {1} {2} {3}\n", item.id, item.displayName, 
        item.slug, item.imageUrl);
}

or

var list = JsonConvert.DeserializeObject<List<MyItem>>(json);

public class MyItem
{
    public string id;
    public string displayName;
    public string name;
    public string slug;
    public string imageUrl;
}
