C#-反序列化JSON对象 [英] C# - deserialize JSON object

问题描述

我正在尝试将以下json绑定到列表，请注意，每个字符串可以包含多个元素，因此列表如下所示:

I am trying to bind the following json to a list, note that each string can contain more than one element, so the list would look like this:

红色，黑色

蓝色

橙色，蓝色，红色，黑色，粉红色

orange,blue,red,black,pink

[
 {
    "shoes": [
      "red",
      "black"
    ]
  },
  {
    "shoes": [
      "blue"
    ]
  },
  {
    "shoes": [
      "orange",
      "blue",
      "red",
      "black",
      "pink"
    ]
  }
]

这是我到目前为止所拥有的，数量不多:

Here is what I have so far, it's not much:

public class Shoes
{
   [JsonProperty("colors")]
   public IList<string> Colors { get; set; }
}

在main内，我正在调用实际的链接(不幸的是，我无法在此处提供它)

within main, I am calling the actual link (unfortunately I can't provide it here)

using (WebClient wc = new WebClient())
{               
    string json = wc.DownloadString(@"JSONlink");
    Shoes shoe = JsonConvert.DeserializeObject<Shoes>(json);
}

它给了我以下错误:

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'xxx' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.

我在这方面没有很多经验，所以任何帮助都会很棒.谢谢.

I don't have a lot of experience in this area, so any help would be great. Thanks.

推荐答案

示例JSON包含一个对象列表，每个对象代表一个 Shoe .表示JSON中颜色集合的属性称为 shoes ，因此该类应如下所示:

The sample JSON contains a list of objects, each an element representing a Shoe. The property representing the collection of colours in the JSON is called shoes so the class should look like this:

public class Shoe
{
   [JsonProperty("shoes")]
   public IList<string> Colors { get; set; }
}

您还需要反序列化为一系列鞋子，而不是单个实例:

You also need to de-serialize to a collection of shoes not a single instance:

var shoes = JsonConvert.DeserializeObject<List<Shoe>>(json);
