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();
}

. net 5内置了在System.Text.Json命名空间下处理JSON解析、序列化、反序列化的类。下面是一个序列化器的例子，它将。net对象转换为JSON字符串，
using System.Text.Json;
using System.Text.Json.Serialization;
private string ConvertJsonString(object obj)
{
JsonSerializerOptions options = new JsonSerializerOptions();
options.WriteIndented = true; //Pretty print using indent, white space, new line, etc.
options.NumberHandling = JsonNumberHandling.AllowNamedFloatingPointLiterals; //Allow NANs
string jsonString = JsonSerializer.Serialize(obj, options);
return jsonString;
}

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

对于那些问我如何使用c#在。net中获得格式化JSON并想要看到如何立即使用它的人和一行爱好者。以下是缩进的JSON字符串一行代码:
有两种知名的JSON格式化器或解析器可以序列化:
Newtonsoft Json。网版:
using Newtonsoft.Json;
var jsonString = JsonConvert.SerializeObject(yourObj, Formatting.Indented);
.Net 7版本:
using System.Text.Json;
var jsonString = JsonSerializer.Serialize(yourObj, new JsonSerializerOptions { WriteIndented = true });
onlineer使用Newtonsoft.Json.Linq:
string prettyJson = JToken.Parse(uglyJsonString).ToString(Formatting.Indented);
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()
