Question

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;
    }

这是我用来序列化模型实例的代码：

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

然后，我的val如下所示：

{
    "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,
        "Minute": 0,
        "Month": 1,
        "Offset": {
            "Ticks": -216000000000,
            "Days": 0,
            "Hours": -6,
            "Milliseconds": 0,
            "Minutes": 0,
            "Seconds": 0,
            "TotalDays": -0.25,
            "TotalHours": -6,
            "TotalMilliseconds": -21600000,
            "TotalMinutes": -360,
            "TotalSeconds": -21600
        },
        "Second": 21,
        "Ticks": 636838848218000000,
        "UtcTicks": 636839064218000000,
        "TimeOfDay": {
            "Ticks": 218000000,
            "Days": 0,
            "Hours": 0,
            "Milliseconds": 800,
            "Minutes": 0,
            "Seconds": 21,
            "TotalDays": 0.000252314814814815,
            "TotalHours": 0.00605555555555556,
            "TotalMilliseconds": 21800,
            "TotalMinutes": 0.363333333333333,
            "TotalSeconds": 21.8
        },
        "Year": 2019
    },
    "PlannedOutage": "No",
    "Severity": "Critical",
    "SiteName": "BA_ISSI",
    "SiteNumber": null,
    "SourceAgentIp": null,
    "Message": "SITE TRUNKING, DEVICE CRITICAL MALFUNCTION"
}

如您所见，我的日期对象看起来里面有很多东西，而不是我需要的东西。然后，当我尝试对字符串进行反序列化时：

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

我收到错误消息...

解析值{时遇到意外字符。路径“日期”，第1行，位置64。|

如何使序列化功能使DateTimeOffset的序列化更加简洁并且不会引起错误？

在我的.Net Core项目中，我无法访问Newtonsoft（据我所知）。

不确定这是否是实现要求，但有适用于.Net Core的Newtonsoft.Json nuget程序包（当前为12.0.1版）。因此，如果您能够重新实现您的解决方案以利用它，则可以通过安装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();
        }

    }
}

这将产生以下json：

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

如何从JsonNet序列化DateTimeOffset？
