连载字典< INT，对象>使用JSON.net？ [英] Serialize Dictionary<int,object> using JSON.net?

问题描述

我试图用JSON.net序列化词典。

I'm trying to use JSON.net to serialize a Dictionary.

使用

JsonConvert.SerializeObject(theDict);

下面是我的结果。

{
  "1": {
    "Blah1": false,
    "Blah2": false,
    "Blah3": "None",
    "Blah4": false
  },
  "2": {
    "Blah1": false,
    "Blah2": false,
    "Blah3": "None",
    "Blah4": false
  },
  "3": {
    "Blah1": false,
    "Blah2": false,
    "Blah3": "None",
    "Blah4": false
  },
  ...
  ...
  ...
}  

有没有办法来序列本字典，这样的按键呈现为有效的JavaScript变量？

Is there a way to serialize this dictionary such that the keys are rendered as valid javascript variables?

我也开到序列化字典的其它策略。

I am also open to other strategies of serializing the dictionary.

推荐答案

这是生成的JSON 词典<的正确方法; INT，...> 。其原因是， JSON的需要的所有按键都带引号的字符串。

That is the correct way to generate the JSON for Dictionary<int,...>. The reason is that JSON requires that all keys are quoted-string literals.

JS在这方面更放松一点：但是JSON是JS对象文字的受限制的。在任何情况下，的 JavaScript中的所有属性名称都是字符串的。 （它们被隐式转换为需要的。）因此，（{1：2}）[1]）和（{1： 2}）[1]）是如JS同样有效（两者计算结果为 2 ），但只有 { 1：2} 是有效的JSON

JS is a little more relaxed in this regard: but JSON is a restricted form of JS object literals. In any case, all property names in JavaScript are strings. (They are implicitly converted as needed.) Thus, ({1: 2})["1"]) and ({"1": 2})[1]) are as equally valid in JS (and both evaluate to 2), but only {"1": 2} is valid JSON.

如果目标类型反序列化回为词典< INT。 ...方式> 然后它会自动照顾的键转​​换到 INT ，IIRC

If the target Type to deserialize back into is Dictionary<int,...> then it will automatically take care of the conversions in the keys to int, IIRC.

我不知道的一种方式来获得JSON.NET产生非直接JSON它;-)可以与循环顶层结构，比如做每个 KeyValuePair< INT，...> 并生成JSON用于与改良的JS代码沿着每个条目：

I am not aware of a way to get JSON.NET to generate non-JSON directly ;-) It could be done with looping the top-level construct, e.g. each KeyValuePair<int,...> and generating the JSON for each individual entry along with the "modified" JS code:

foreach (var p in dict) {
    var k = p.Key;
    var v = p.Value;
    Emit(string.Format(
        "var name{0} = {1};",
        k, JsonConvert.SerializeObject(v)));
}

其中，的Emit 是无论是用于收集输出......我会建议只是正常的JSON如果可能的话，虽然。

Where Emit is whatever is used to collect the output... I would recommend "just normal JSON" if at all possible, though.

编码愉快。
