便攜式庫錯誤

我有一個的WebAPI返回以下JSON而我試圖反序列化對象下面便攜式庫錯誤

JSON對象

{ 
    "results": [{ 
      "id": 123456, 
      "fullName": "Foo Bar", 
      "localName": null, 
      "jobPosition": "ME", 
      "jobCompanyName": "EXTRA", 
      "jobLocationCountry": "United States of America", 
      "jobLocationCity": "San Francisco", 
      "jobCountrySubdivision": "California", 
      "boards": [], 
      "restrictionsIndicator": false, 
      "personRestriction": null, 
      "jobRestriction": null 
     }, { 
      "id": 789101, 
      "fullName": "Foo Bar", 
      "localName": null, 
      "jobPosition": null, 
      "jobCompanyName": "Unknown", 
      "jobLocationCountry": "Unknown", 
      "jobLocationCity": "Unknown", 
      "jobCountrySubdivision": "Unknown", 
      "boards": [{ 
        "companyId": 667525, 
        "companyName": "FOO BAR COMPANY", 
        "companyOffLimits": null, 
        "restrictionCategoryId": null 
       } 
      ], 
      "restrictionsIndicator": false, 
      "personRestriction": null, 
      "jobRestriction": null 
     } 
    ], 
    "totalCount": 2, 
    "pageNumber": 1, 
    "resultsPerPage": 100 
}

C＃類

public class Rootobject 
{ 
    public Result[] results { get; set; } 
    public int totalCount { get; set; } 
    public int pageNumber { get; set; } 
    public int resultsPerPage { get; set; } 
} 

public class Result 
{ 
    public int id { get; set; } 
    public string fullName { get; set; } 
    public object localName { get; set; } 
    public string jobPosition { get; set; } 
    public string jobCompanyName { get; set; } 
    public string jobLocationCountry { get; set; } 
    public string jobLocationCity { get; set; } 
    public string jobCountrySubdivision { get; set; } 
    public Board[] boards { get; set; } 
    public bool restrictionsIndicator { get; set; } 
    public int? personRestriction { get; set; } 
    public int? jobRestriction { get; set; } 
} 

public class Board 
{ 
    public int companyId { get; set; } 
    public string companyName { get; set; } 
    public int? companyOffLimits { get; set; } 
    public object restrictionCategoryId { get; set; } 
}

該DLL是一個可移植的類庫，它是.NET 4.5，我有JSON .net（10.0.1）通過nuget安裝，但便攜式庫連接到Mac上的xamarin IOS項目。

如果被反序列化的JSON沒有Boards它工作得很好，但如果有Board，我會收到以下消息。

Unable to find a constructor to use for type Board. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute. Path 'results[1].boards[0].companyId'

我使用的設置是：

var settings = new Newtonsoft.Json.JsonSerializerSettings 
{ 
    NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore, 
    ContractResolver = new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver(), 

};

我曾嘗試以下方法來得到它的序列：

var obj = Newtonsoft.Json.JsonConvert.DeserializeObject<Rootobject>(_jsonString, settings);
var jobject = Newtonsoft.Json.JsonConvert.DeserializeAnonymousType(_jsonString, new Rootobject());

我曾嘗試以下

放在一個默認的構造函數
命名爲班級的所有參數的構造函數
添加屬性到構造
更換板卡列表
取出板子屬性

但仍然沒有喜悅。它不會爲我反序列化。

「我收到以下消息」 - 您沒有發佈錯誤消息的文本。當我認爲你的意思是「反序列化」時，你還會使用「序列化」這個術語幾次 - 這是令人困惑的。 – Jason

對不起，試圖一次做一百萬件事。問題已更新。 – Qpirate

我認爲你必須修改這個

public class Board 
{ 
    public int companyId { get; set; } 
    public string companyName { get; set; } 
    public int? companyOffLimits { get; set; } 
    public object restrictionCategoryId { get; set; } 

    **public Board(){}** 
}

而且在其他類

或也改變

public Board[] boards { get; set; }

到

public List<Board> boards { get; set; }

嘗試....

Nope已經嘗試過'放入默認構造函數' – Qpirate

我已更新... –

也嘗試過'將主板更改爲列表' – Qpirate
