C# 使用JSON.net时自动更改日期格式

我有一个JSON字符串，如下所示：

  }, {
    "position" : 10
  } ],

    "currency" : "USD",
    "amount" : 6800.0,

      "PND" : 3944.00,
      "EUR" : 4896.00
    },
    "amountCurrencies" : {
      "USD" : 6800.00,
      "PND" : 3944.00,
      "EUR" : 4896.00
    }
  }
}

我从以下位置使用库：
解析JSON并更新对象的属性

dynamic jsonObj = JObject.Parse(json);
dynamic furnitureItem = jsonObj.result.furnitureItem;

furnitureItem.title = "Hello";
furnitureItem.description = "World";

但是，在更新属性后，日期值会发生更改

furnitureItem.ToString();//I am using this line to get updated JSON

JSON:

我希望保持日期值不变

不希望更改自动发生的时区。

这是JSON.NET的文档页面，它向您展示了如何控制序列化日期的格式：

从文件中：

// default as of Json.NET 4.5
string isoJson = JsonConvert.SerializeObject(entry);
    // {"Details":"Application started.","LogDate":"2009-02-15T00:00:00Z"}

JsonSerializerSettings microsoftDateFormatSettings = new JsonSerializerSettings
{
    DateFormatHandling = DateFormatHandling.MicrosoftDateFormat
};

string microsoftJson = JsonConvert.SerializeObject(
    entry, microsoftDateFormatSettings);
    // {"Details":"Application started.","LogDate":"\/Date(1234656000000)\/"}

string javascriptJson = JsonConvert.SerializeObject(
    entry, new JavaScriptDateTimeConverter());
    // {"Details":"Application started.","LogDate":new Date(1234656000000)}

---

如果不打算处理日期，可以将其保留为字符串

JsonReader jsonReader = new JsonTextReader(new StringReader(json)) { DateParseHandling = DateParseHandling.None };
dynamic jsonObj = JObject.Load(jsonReader);

是的，JSON就是这样做的。约会很难玩。但是这篇文章可能会帮助你Hi@pptitle，谢谢你的回复，我没有在我的代码中的任何地方使用

反序列化

功能，类似的问题：

JsonReader jsonReader = new JsonTextReader(new StringReader(json)) { DateParseHandling = DateParseHandling.None };
dynamic jsonObj = JObject.Load(jsonReader);
