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();
}

当前回答

使用System.Text.Json设置JsonSerializerOptions。writeindent = true:

JsonSerializerOptions options = new JsonSerializerOptions { WriteIndented = true };
string json = JsonSerializer.Serialize<Type>(object, options);

其他回答

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

下面的代码为我工作:

JsonConvert.SerializeObject(JToken.Parse(yourobj.ToString()))

. 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;
}

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);
}

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());
}
