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();
}

onlineer使用Newtonsoft.Json.Linq:
string prettyJson = JToken.Parse(uglyJsonString).ToString(Formatting.Indented);

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 });
所有这些都可以在一行中完成:
string jsonString = JsonConvert.SerializeObject(yourObject, 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()
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
对于使用。net Core 3.1的UTF8编码的JSON文件，我最终能够使用基于微软的信息:https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-how-to#utf8jsonreader-utf8jsonwriter-and-jsondocument的JsonDocument
string allLinesAsOneString = string.Empty;
string [] lines = File.ReadAllLines(filename, Encoding.UTF8);
foreach(var line in lines)
allLinesAsOneString += line;
JsonDocument jd = JsonDocument.Parse(Encoding.UTF8.GetBytes(allLinesAsOneString));
var writer = new Utf8JsonWriter(Console.OpenStandardOutput(), new JsonWriterOptions
{
Indented = true
});
JsonElement root = jd.RootElement;
if( root.ValueKind == JsonValueKind.Object )
{
writer.WriteStartObject();
}
foreach (var jp in root.EnumerateObject())
jp.WriteTo(writer);
writer.WriteEndObject();
writer.Flush();
