Hw从JsonNet序列化DateTimeOffset?

jsonnet serialization json c#

Matt Spinks · 技术社区 · 6 年前

我正在尝试将模型序列化为Json格式。这是我的模型:

    public class UemSiteAvailabilityDetailsRec
    {
        public string UemAlias;
        public string IpAddress;
        public DateTimeOffset Date;
        public string PlannedOutage;
        public string Severity;
        public string SiteName;
        public string SiteNumber;
        public string SourceAgentIp;
        public string Message;
    }

这是我序列化模型实例的代码:

var rec = //GETTING REC FROM DATABASE
var val = JsonNet.Serialize(rec);

在那之后,我的 val

{
    "UemAlias": "***.***.**.**",
    "IpAddress": "***.***.**.**",
    "Date": {
        "DateTime": "01\/24\/2019 00:00:21",
        "UtcDateTime": "01\/24\/2019 06:00:21",
        "LocalDateTime": "01\/24\/2019 00:00:21",
        "Date": "01\/24\/2019 00:00:00",
        "Day": 24,
        "DayOfWeek": 4,
        "DayOfYear": 24,
        "Hour": 0,
        "Millisecond": 800,

            "TotalHours": -6,

            "TotalMinutes": -360,

        },

            "Days": 0,
            "Hours": 0,
            "Milliseconds": 800,
            "Minutes": 0,
            "Seconds": 21,

    },
    "PlannedOutage": "No",
    "Severity": "Critical",
    "SiteName": "BA_ISSI",
    "SiteNumber": null,
    "SourceAgentIp": null,
    "Message": "SITE TRUNKING, DEVICE CRITICAL MALFUNCTION"
}

正如你所看到的,我的日期对象看起来里面的东西比我需要的要多。稍后,当我尝试像这样反序列化字符串时:

var rec = JsonConvert.DeserializeObject<UemSiteAvailabilityDetailsModel>(val);

我得到了错误。。。

分析值时遇到意外字符:{.Path“Date”, 第1行,第64位|

如何使序列化函数 DateTimeOffset 序列化更简洁且不会导致错误?

在我的.Net核心项目中,我无法访问Newtonsoft(据我所知)。

不确定这是否是实现要求,但是有可用于.NETCore的Newtonsoft.jsonNuGet包(当前版本为12.0.1)。因此,如果您能够重新实现您的解决方案以利用它,您可以通过安装它然后使用它来解决问题:

using System;
using Newtonsoft.Json;

namespace ConsoleApp
{
    public class Program
    {
        public class UemSiteAvailabilityDetailsRec
        {
            public string UemAlias;
            public string IpAddress;
            public DateTimeOffset Date = new DateTimeOffset(new DateTime(1980, 7, 7));
            public string PlannedOutage;
            public string Severity;
            public string SiteName;
            public string SiteNumber;
            public string SourceAgentIp;
            public string Message;
        }

        static void Main(string[] args)
        {
            var toSerialize = new UemSiteAvailabilityDetailsRec();
            string val = JsonConvert.SerializeObject(toSerialize);
            Console.WriteLine(val);
            Console.ReadKey();
        }

    }
}

{
    "UemAlias": "",
    "IpAddress": null,
    "Date": "1980-07-07T00:00:00-05:00",
    "PlannedOutage": null,
    "Severity": null,
    "SiteName": null,
    "SiteNumber": null,
    "SourceAgentIp": null,
    "Message": null
}
