我如何得到格式化的JSON在.NET使用c# ?

我正在使用. net JSON解析器，并想序列化我的配置文件，使其可读。所以不要:

{"blah":"v", "blah2":"v2"}

我想要更好的东西，比如:

{
    "blah":"v", 
    "blah2":"v2"
}

我的代码是这样的:

using System.Web.Script.Serialization; 

var ser = new JavaScriptSerializer();
configSz = ser.Serialize(config);
using (var f = (TextWriter)File.CreateText(configFn))
{
    f.WriteLine(configSz);
    f.Close();
}

修饰现有JSON的最短版本:(编辑:使用JSON.net)

JToken.Parse("mystring").ToString()

输入:

{"menu": { "id": "file", "value": "File", "popup": { "menuitem": [ {"value": "New", "onclick": "CreateNewDoc()"}, {"value": "Open", "onclick": "OpenDoc()"}, {"value": "Close", "onclick": "CloseDoc()"} ] } }}

输出:

{
  "menu": {
    "id": "file",
    "value": "File",
    "popup": {
      "menuitem": [
        {
          "value": "New",
          "onclick": "CreateNewDoc()"
        },
        {
          "value": "Open",
          "onclick": "OpenDoc()"
        },
        {
          "value": "Close",
          "onclick": "CloseDoc()"
        }
      ]
    }
  }
}

漂亮地打印一个对象:

JToken.FromObject(myObject).ToString()

如果你有一个JSON字符串，想要“美化”它，但不想将它序列化到一个已知的c#类型，那么下面的方法就可以了(使用JSON.NET):

using System;
using System.IO;
using Newtonsoft.Json;

class JsonUtil
{
    public static string JsonPrettify(string json)
    {
        using (var stringReader = new StringReader(json))
        using (var stringWriter = new StringWriter())
        {
            var jsonReader = new JsonTextReader(stringReader);
            var jsonWriter = new JsonTextWriter(stringWriter) { Formatting = Formatting.Indented };
            jsonWriter.WriteToken(jsonReader);
            return stringWriter.ToString();
        }
    }
}

using System.Text.Json;
...
var parsedJson = JsonSerializer.Deserialize<ExpandoObject>(json);
var options = new JsonSerializerOptions() { WriteIndented = true };
return JsonSerializer.Serialize(parsedJson, options);

这对我很管用。以防有人在找VB。净版。

@imports System
@imports System.IO
@imports Newtonsoft.Json
    
Public Shared Function JsonPrettify(ByVal json As String) As String
  Using stringReader = New StringReader(json)

    Using stringWriter = New StringWriter()
      Dim jsonReader = New JsonTextReader(stringReader)
      Dim jsonWriter = New JsonTextWriter(stringWriter) With {
          .Formatting = Formatting.Indented
      }
      jsonWriter.WriteToken(jsonReader)
      Return stringWriter.ToString()
    End Using
  End Using
End Function

onlineer使用Newtonsoft.Json.Linq:

string prettyJson = JToken.Parse(uglyJsonString).ToString(Formatting.Indented);
