JSON.NET反序列化/序列化JsonProperty JsonObject

Question

我有一個關於使用Newtonsoft JSON.NET庫進行反序列化/序列化的問題：

我收到這個json：

 {
    "customerName" : "Lorem",
    "id": 492426
    "sequence": 1232132
    "type" : 3,
    "status" : 0,
    "streetNumber" : 9675,
    "streetName" : "Lorem",
    "suite" : null,
    "city" : "IPSUM",
    "provinceCode" : "QC",
    "postalCode" : "H1P1Z3",
    "routeNumber" : 0,
    "poBox" : 0,
    "streetType" : "CH",
    "userId" : 25,
    "streetDirection" : null,
    "countryCode" : "CA",
    "customerNickName" : "Lorem ipsum",
    "streetSuffix" : null,
    "contacts" : [ {
        "status" : 0,
        "telephone" : 4445555555,
        "extension" : 0,
        "email" : "webtest@test.com",
        "id" : 50,
        "fullName" : "name",
        "department" : "department"
    } ],
    "attribute" : {
      "nbrOfUse" : 1,
      "lastUse" : "2013-01-03T09:57:28-0500"
    }       
}

我的問題在於這一部分：

    "attribute" : {
      "nbrOfUse" : 1,
      "lastUse" : "2013-01-03T09:57:28-0500"
    }

在我的address類中，是否可以執行以下操作：

    [JsonProperty(PropertyName = "lastUse", ObjectName="attribute")]
    or [JsonProperty(PropertyName = "lastUse")][JsonObject(PropertyName = "attribute")]
    or something like this ...
    public DateTime? LastUse { get; set; }

我不會使用JObject.Parse(...)因為json非常大

我的課 ：

public class Address
{
    /// <summary>
    /// Gets or sets the id of the <see cref="Address" /> class.
    /// </summary>
    /// <value>

    [JsonProperty(PropertyName = "id")]
    public int Id { get; set; }

    [Display(Name = "StreetDirection", ResourceType = typeof(AccountModels))]

    [Display(Name = "CompanyPostalCode", ResourceType = typeof(AccountModels))]
    [PostalCode("Country", ErrorMessageResourceType = typeof(GenericValidator), ErrorMessageResourceName = "PostalCode")]
    public string PostalCode { get; set; }

Answer 1

您需要為“屬性”創建自定義類型，如：

    public class Attribute {

        [JsonProperty(PropertyName = "nbrOfUse")]
        public int _nbrOfUse { get; set; }
        [JsonProperty(PropertyName = "streetType")]
        [Display(Name = "lastUse", ResourceType = typeof(AccountModels))]
        public string _lastUse { get; set; }

    }

並在Address類中創建一個Object of Attribute類。

Answer 2

你可以使用的一個可能的解決方案，可能看起來有點hacky，就是在解析它之前操縱JSON字符串，例如使用正則表達式。

你會識別和替換

"attribute" : {
   "nbrOfUse" : 1,
   "lastUse" : "2013-01-03T09:57:28-0500"
 }

同

"lastUse" : "2013-01-03T09:57:28-0500"

然后，您的序列化程序將識別DateTime？ 名為“lastUsed”的屬性
