Yahoo聯繫API Json deserilization問題

Question

我反序列化雅虎聯繫人api的json響應一切都很順利，但我得到的問題在一個字段fields，它的一個數組但在所有元素value是不同的不同，如何處理它。在兩個字段中，這是字符串和其他元素對象。這裏是我的樣品JSON

"fields": [ 
     { 
     "created": "2008-12-29T13:47:21Z", 
     "updated": "2008-12-29T13:47:21Z", 
     "uri": "http://social.yahooapis.com/v1/user/ASASASASASASA/contact/8/email/18", 
     "id": "18", 
     "type": "email", 
     "value": "papi@ymail.com", 
     "editedBy": "OWNER" 
     }, 
     { 
     "created": "2010-03-30T07:02:04Z", 
     "updated": "2011-06-25T05:01:51Z", 
     "uri": "http://social.yahooapis.com/v1/user/ASASASASASASA/contact/8/guid/42", 
     "id": "42", 
     "type": "guid", 
     "value": "BMM5JTQVDB7G4EBPO2D5ESE3TI", 
     "editedBy": "OWNER", 
     "isConnection": "false" 
     }, 
     { 
     "created": "2008-12-29T13:47:21Z", 
     "updated": "2008-12-29T13:47:21Z", 
     "uri": "http://social.yahooapis.com/v1/user/ASASASASASASA/contact/8/name/17", 
     "id": "17", 
     "type": "name", 
     "value": { 
     "givenName": "Hitesh", 
     "middleName": null, 
     "familyName": "Lohar", 
     "prefix": null, 
     "suffix": null, 
     "givenNameSound": null, 
     "familyNameSound": null 
     }, 
     "editedBy": "OWNER" 
     } 
    ] 

我創建了以下類現場

public class YahooField 
    { 
     [JsonProperty("created")] 
     public string Created { get; set; } 

     [JsonProperty("updated")] 
     public string Updated { get; set; } 

     [JsonProperty("uri")] 
     public string Uri { get; set; } 

     [JsonProperty("id")] 
     public string Id { get; set; } 

     [JsonProperty("type")] 
     public string Type { get; set; } 

     //here confusion 
     //[JsonProperty("value")] 
     //public (String or class) Value { get; set; } 

     [JsonProperty("editedBy")] 
     public string EditedBy { get; set; } 

     [JsonProperty("isConnection")] 
     public string IsConnection { get; set; } 
    } 

Answer 1

value屬性是另一個對象。 創建一個名爲ValueField新類，並添加一些屬性：

1. 給定名稱
2. 中間名
3. FamilyName
4. 前綴
5. 後綴
6. GivenNameSound
7. FamilyNameSound

這個類的屬性添加到您的YahooField類

public class YahooField 
    { 
     [JsonProperty("created")] 
     public string Created { get; set; } 

     [JsonProperty("updated")] 
     public string Updated { get; set; } 

     [JsonProperty("uri")] 
     public string Uri { get; set; } 

     [JsonProperty("id")] 
     public string Id { get; set; } 

     [JsonProperty("type")] 
     public string Type { get; set; } 

     [JsonProperty("value")] 
     public ValueField Value { get; set; } 

     [JsonProperty("editedBy")] 
     public string EditedBy { get; set; } 

     [JsonProperty("isConnection")] 
     public string IsConnection { get; set; } 
    } 

你應該寫自己的合同，解析器來檢測，如果屬性值的類型爲String與否。這樣你就可以中斷默認行爲並實現自己的邏輯。

只需從DefaultContractResolver派生CustomContractResolver並覆蓋實現所需的虛擬方法。

public class CustomContractResolver: DefaultContractResolver 
{ 
//override the methods you need. 
} 

您可以通過執行設置自定義的合同解析如下：

JsonConvert.SerializeObject(
    product, 
    Formatting.Indented, 
    new JsonSerializerSettings { ContractResolver = new CustomContractResolver() } 
);
