C＃排序JSON字符串键 [英] C# Sort JSON string keys

问题描述

我想JSON字符串转换

I'd like to convert the JSON string

"{ \"birthday\": \"1988-03-18\", \"address\": { \"state\": 24, \"city\": 8341, \"country\": 1 } }"

到

"{ \"address\": { \"city\": 8341, \"country\": 1, \"state\": 24 }, \"birthday\": \"1988-03-18\" }"

请注意：我不使用通讯排序的版本（因为键顺序并不重要），我需要一个有序的版本进行本地测试（通过比较JSON字符串）。

NOTE: I'm not using the sorted version for communication (because the key order doesn't really matter), I need a sorted version to perform local tests (by comparing JSON strings).

编辑： I4V指出使用的Json的解决方案。净，我宁可使用不必包含任何第三方库（其实我使用的是内置的System.Json在我的应用程序）

I4V pointed a solution that uses Json.Net, I would rather use a solution that doesn't need to include any 3rd party library (actually I'm using the built in System.Json in my application)

我张贴由I4V +一些测试的这里。谢谢大家。

I posted a gist with the solution provided by I4V + some testing here. Thank you all.

推荐答案

我将使用的Json此

I will use Json.Net for this

string json = @"{ ""birthday"": ""1988-03-18"", ""address"": { ""state"": 24, ""city"": 8341, ""country"": 1 } }";
var jObj = (JObject)JsonConvert.DeserializeObject(json);
Sort(jObj);
string newJson = jObj.ToString();

---

---

void Sort(JObject jObj)
{
    var props = jObj.Properties().ToList();
    foreach (var prop in props)
    {
        prop.Remove();
    }

    foreach (var prop in props.OrderBy(p=>p.Name))
    {
        jObj.Add(prop);
        if(prop.Value is JObject)
            Sort((JObject)prop.Value);
    }
}

修改

一个尝试与 System.Json ，但我不知道关于 OrderByDescending （或排序依据）。

A try with System.Json but I am not sure about OrderByDescending ( or OrderBy).

var jObj = (System.Json.JsonObject)System.Json.JsonObject.Parse(json);
Sort2(jObj);
var newJson = jObj.ToString();

---

---

void Sort2(System.Json.JsonObject jObj)
{
    var props = jObj.ToList();
    foreach (var prop in props)
    {
        jObj.Remove(prop.Key);
    }

    foreach (var prop in props.OrderByDescending(p => p.Key))
    {
        jObj.Add(prop);
        if (prop.Value is System.Json.JsonObject)
            Sort2((System.Json.JsonObject)prop.Value);
    }
}
