Question

我正在使用返回JSON数据的Web服务，并且在很多情况下，服务会在一个对象中返回几个属性，我想将它们分组到C＃端的类中。考虑一个类结构，如：

  class Person
  {
      public Address Address { get; set; }
      public string Name {  get; set; }
  }

  class Address
  {
      public string StreetAddress { get; set; }
      public string City {  get; set; }
      public string ZipCode {  get; set; }
  }

和JSON数据一样：

{ "Name" : "Pilchie",
"StreetAddress" : "1234 Random St",
"City" : "Nowheretown",
"Zip" : "12345"
}

是否可以归因于我的Person和Address类，以便它们序列化/反序列化为此格式？

Answer 1

我认为你不能让JSON.NET一次性完成这一切 - 你必须手动创建Person对象。但是，您可以在不创建单独的DTO类的情况下完成此操作。例如：

var jsonText = "{ \"Name\" : \"Pilchie\"," +
            "\"StreetAddress\" : \"1234 Random St\"," +
            "\"City\" : \"Nowheretown\"," +
            "\"Zip\" : \"12345\"" +
            "}";
JObject jsonObject = (JObject) JsonConvert.DeserializeObject(jsonText);

var person =
    new Person
    {
        Address = new Address
                    {
                    City = (String) jsonObject["City"],
                    StreetAddress = (String) jsonObject["StreetAddress"],
                    ZipCode = (string) jsonObject["Zip"]
                    },
        Name = (string) jsonObject["Name"]
    };

序列化：

JsonConvert.SerializeObject(
    new
    {
        person.Name,
        person.Address.StreetAddress,
        person.Address.City,
        Zip = person.Address.ZipCode
    });

我认为，对您正在使用的数据进行反序列化的最简单方法是创建一个与JSON数据格式匹配的简单DTO对象。然后，您可以使用AutoMapper或类似的库轻松地将数据映射到新结构。

这完全取决于您将如何使用数据。如果您只想访问地址属性，可以执行以下操作：

class Person
{
    public string Name { get; set; }
    public string StreetAddress { get; set; }
    public string City { get; set; }
    public string ZipCode { get; set; }

    [ScriptIgnore]
    public Address Address { get {return new Address(){StreetAddress = this.StreetAddress,
                                                       City = this.City,
                                                       ZipCode = this.ZipCode} } }
}

Answer 4

var person = JsonConvert.DeserializeObject<Person>(json);

class Person
{
    [JsonProperty("StreetAddress")]
    private string _StreetAddress { get; set; }

    [JsonProperty("City")]
    private string _City { get; set; }

    [JsonProperty("Zip")]
    private string _ZipCode { get; set; }

    public string Name { get; set; }

    public Address Address
    {
        get
        {
            return new Address() { City = _City, StreetAddress = _StreetAddress, ZipCode = _ZipCode };
        }
    }
}

class Address
{
    public string StreetAddress { get; set; }
    public string City { get; set; }
    public string ZipCode { get; set; }
}

使用JSon.net将平面JSON数据反序列化为结构
