使用DataContractJsonSerializer的自定义DateTime序列化/反序列化 [英] Custom DateTime serialization/deserialization using DataContractJsonSerializer

问题描述

对于对象图中的所有DateTime属性，如何使用DataContractJsonSerializer将默认的JSON DateTime序列化/反序列化更改为自定义格式?

How to change the default JSON DateTime serialization/deserialization to a custom format using DataContractJsonSerializer for all DateTime properties in the object graph?

Json.Net库处理了这个问题，但是我不能在这个项目中使用它.

The Json.Net library deals with this but I can't use that in this project.

我尝试了IDataContractSurrogate，但是我无法访问值-> DateTimes的字符串转换.

I tried IDataContractSurrogatebut I cannot access the value -> string conversion for DateTimes.

模型和预期的JSON是:

The model and expected JSON are:

[DataContract]
public class Client
{
    [DataMember(Name = "id")]
    public int Id {get; set; }
    [DataMember(Name = "name")]
    public string Name {get; set; }
    [DataMember(Name = "contacts")]
    public IList<Contact> Contacts {get; set; }
    [DataMember(Name = "created")]
    public DateTime Created {get; set; }
    [DataMember(Name = "changed")]
    public DateTime Changed {get; set; }
}

[DataContract]
public class Contact
{
    [DataMember(Name = "name")]
    public string Name {get; set; }
    [DataMember(Name = "created")]
    public DateTime Created {get; set; }
}

---

{
    "id": 123,
    "name": "Client Name",
    "contacts": [
        {
            "name": "Contact Name",
            "created": "2014-01-25 02:12:43"
        }
    ],
    "created": "2014-01-25 01:11:23"
    "changed": "2014-01-25 03:22:41"
}

推荐答案

我可能遗漏了一些东西，但是在创建序列化程序时尝试在设置中传递所需的日期和时间格式:

I might be missing something, but try passing the desired date and time format in the settings when creating the serializer:

var serializer = new DataContractJsonSerializer(
    typeof(Client),
    new DataContractJsonSerializerSettings {
        DateTimeFormat = new DateTimeFormat("yyyy-MM-dd hh:mm:ss"),
    });
