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();
}

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

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()
Net Core App
var js = JsonSerializer.Serialize(obj, new JsonSerializerOptions {
WriteIndented = true
});
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();
}
}
}
下面的代码为我工作:
JsonConvert.SerializeObject(JToken.Parse(yourobj.ToString()))
下面是一个使用微软System.Text.Json库的解决方案:
static string FormatJsonText(string jsonString)
{
using var doc = JsonDocument.Parse(
jsonString,
new JsonDocumentOptions
{
AllowTrailingCommas = true
}
);
MemoryStream memoryStream = new MemoryStream();
using (
var utf8JsonWriter = new Utf8JsonWriter(
memoryStream,
new JsonWriterOptions
{
Indented = true
}
)
)
{
doc.WriteTo(utf8JsonWriter);
}
return new System.Text.UTF8Encoding()
.GetString(memoryStream.ToArray());
}
