使用 JSON 序列化程序将对象数组序列化为一个对象，并为 C# 中的每个对象指定一个命名属性

我有一个列表，当序列化为 JSON 时，它会给我一个对象数组。但是，我需要序列化版本的结构如下：

{
  "item3":{
    "id":3,
    "name":"monkey"
  },
  "item4":{
    "id":4,
    "name":"turtle"
  }
}

目前，JSON 序列化的结构如下：

[
  {
    "id":3,
    "name":"monkey"
  },
  {
    "id":4,
    "name":"turtle"
  }
]

我的目标是能够通过项目 ID 而不是数字索引（即 arr["item3"].名称而不是 arr[0].name）。

I have a List that, when serialized as JSON gives me an array of objects. However, I need the serialized version to be structured as follows:

{
  "item3":{
    "id":3,
    "name":"monkey"
  },
  "item4":{
    "id":4,
    "name":"turtle"
  }
}

Currently, the JSON serialization is structured like this:

[
  {
    "id":3,
    "name":"monkey"
  },
  {
    "id":4,
    "name":"turtle"
  }
]

My goal is to be able to reference the array by item ID instead of numeric index (ie. arr["item3"].name instead of arr[0].name).

您可能会这样做，只需将数据放入字典中就足够了 JaveScripySerializer：（

var dict = list.ToDictionary(
    item => "item" + item.id);

并序列化字典）

如果没有：

我没有方便的 PC 作为示例，但您应该能够：

请注意，除非您也需要，否则不需要编写反序列化。

如果您遇到困难，我稍后会尝试举一个例子。

You might did that just putting the data into a dictionary is enough for JaveScripySerializer:

var dict = list.ToDictionary(
    item => "item" + item.id);

(and serialize dict)

If not:

I don't have a PC handy for an example, but you should be able to:

write a wrapper class that encapsulated the list/array
use the JavaScriptSerializer class
after creating the serializer, associate the wrapper-type with a custom serializer
in the custom serializer, iterate over the data, adding a key to the dictionary per-item, i.e. data.Add("item"+i,list[i]);

Note you don't need to write a deserialize unless you need that too.

If you get stuck, I'll try to ad an example later.
