Question

我正在尝试处理大量文件并将其数据移动到SharePoint列表中。我对我的请求的SharePoint组件感到非常满意，但我正在努力绕过JSON并对其执行C＃语句。

我使用的JSON采用以下格式：

{
  "details": {
    "persona": "jdfh sjahfj ashd",
    "firstName": "difdfsdfh",
    "surname": "safasfjhgfasdf",
    "email": "dfashfjsahf@dfjhdfjhsd.com",
    "phone": "3256545 421",
    "organisation": "dsfhjafd gas gdf",
    "department": "hsagfhsdgahjf",
    "address": {
      "street": "11/338 shjafg ash fg",
      "suburb": "gsagfghasf",
      "postcode": "4006"
    },
    "questions": {
      "iAmA": "fhsahjfsajhd df as",
      "iWorkAtA": "",
      "iAmSeekingFor": "ahshfjgsfggdh",
      "iAmAMemberOf": "dafjksfhdh",
      "furtherInfoOptIn": true,
      "newsletterOptIn": false,
      "privacyCollection": true
    }
  },
  "orders": [
    {
      "name": "Business Cards",
      "quantity": 8
    },
    {
      "name": "QUITLINE",
      "quantity": 5
    }
  ]
}

根据this StackExchange请求，我尝试使用以下内容创建一个类以反序列化我的内容：

var des = (ResourceOrdersJSONEntity)Newtonsoft.Json.JsonConvert.DeserializeObject(sampleJSON, typeof(ResourceOrdersJSONEntity));

这对我不起作用，我怀疑我是在向错误的道路走下去。我需要学习什么才能获取JSON并将linq语句包装在其中以便处理到SharePoint中？

我收到的错误是：

无法反序列化当前的JSON对象（例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）   进入类型＆＃39; System.Collections.Generic.List`1

要修复此错误，请将JSON更改为JSON数组（例如   [1,2,3]）或更改反序列化类型，使其成为正常的.NET   type（例如，不是像整数这样的基本类型，不是集合类型   像数组或List一样，可以从JSON对象反序列化。   JsonObjectAttribute也可以添加到类型中以强制它   从JSON对象反序列化。

我不太明白它向我表明了什么，而且我确定我的班级结构是问题，但我需要一些指导如何解决它。

以下是我为反序列化创建的类：

主要实体 公共类ResourceOrdersJSONEntity { 公开列表详细信息{get;组; } 公共清单订单{get;组; } }

Answer 1

我只需将ResourceOrdersJSONEntity更改为：

即可让您的代码正常工作

public class ResourceOrdersJSONEntity
{
    public ResourceOrdersDetailsEntity Details { get; set; }
    public List<ResourceOrdersQuantityEntity> Orders { get; set; }
}

Answer 2

尝试使用JsonConvert.DeserializeObject<ResourceOrdersJSONEntity>(sampleJson)方法。它将JSON强制转换为指定的类。

如下所述。您必须将主要实体更改为此

public class ResourceOrdersJSONEntity
{
    public ResourceOrdersDetailsEntity Details { get; set; }
    public List<ResourceOrdersQuantityEntity> Orders { get; set; }
}

在JSON对象中用大括号{}括起来，数组（JSON中唯一一种列表/数组/集合类型）用方括号[]括起来。需要将JSON对象转换为C＃对象，并且需要将JSON数组转换为C＃list / array / collection。这就是为什么当您尝试将"details"对象转换为List时，JSON.net会给您一个错误

Answer 3

您的ResourceOrdersJSONEntity类应如下所示：

public class ResourceOrdersJSONEntity 
{ 
   public List Details { get; set; } 
   public List<ResourceOrdersQuantityEntity> Orders { get; set; } 
}

使用LINQ / C＃
