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

用JavaScriptSerializer来完成这个任务会很困难。
试试JSON.Net。
对JSON进行了少量修改。净的例子
using System;
using Newtonsoft.Json;
namespace JsonPrettyPrint
{
internal class Program
{
private static void Main(string[] args)
{
Product product = new Product
{
Name = "Apple",
Expiry = new DateTime(2008, 12, 28),
Price = 3.99M,
Sizes = new[] { "Small", "Medium", "Large" }
};
string json = JsonConvert.SerializeObject(product, Formatting.Indented);
Console.WriteLine(json);
Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);
}
}
internal class Product
{
public String[] Sizes { get; set; }
public decimal Price { get; set; }
public DateTime Expiry { get; set; }
public string Name { get; set; }
}
}
结果
{
"Sizes": [
"Small",
"Medium",
"Large"
],
"Price": 3.99,
"Expiry": "\/Date(1230447600000-0700)\/",
"Name": "Apple"
}
文档:序列化对象
Json的简短示例代码。网络图书馆
private static string FormatJson(string json)
{
dynamic parsedJson = JsonConvert.DeserializeObject(json);
return JsonConvert.SerializeObject(parsedJson, Formatting.Indented);
}
Net Core App
var js = JsonSerializer.Serialize(obj, new JsonSerializerOptions {
WriteIndented = true
});
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());
}
使用System.Text.Json设置JsonSerializerOptions。writeindent = true:
JsonSerializerOptions options = new JsonSerializerOptions { WriteIndented = true };
string json = JsonSerializer.Serialize<Type>(object, options);
