Question

我正在致电Salesforce API以获取搜索结果。为了连接到销售人员，我使用了强制客户端。

var client = GetForceClient(token);
                string query = "FIND {01} IN ALL FIELDS RETURNING CASE(Id,Account.Name,Case_Id__c,Customer_Ticket_Id__c,Site__r.Name,Order__r.Name,Site__r.Country__c,Status,Subject LIMIT 5 OFFSET 0),Order__c(Order_Name__c,Tech_Service_Type__C,Customer__r.Name,End_Customer__r.Name,Site__r.Site_Name__c,name LIMIT 5 OFFSET 0),SITE__C(ID,Status__c,Address__c,Site_Name__c,NAME)";
                var response = await client.SearchAsync<Search>(query);

在此行中反序列化结果时

 var response = await client.SearchAsync<Search>(query);

正在引发以下错误。

   Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[API.Dto.Search]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
    To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
    Path 'searchRecords', line 1, position 17.

json响应看起来像这样

  "searchRecords" : [ {
    "attributes" : {
      "type" : "Case",

等效的C＃类是这样的：

public class Search
    {
        [JsonProperty("searchRecords")]
        public SearchRecord[] SearchRecords { get; set; }
    }
    public class SearchRecord
    {
        [JsonProperty("attributes")]
        public Attributes Attributes { get; set; }

        [JsonProperty("Id", NullValueHandling = NullValueHandling.Ignore)]
        public string Id { get; set; }

        [JsonProperty("Account", NullValueHandling = NullValueHandling.Ignore)]
        public Account Account { get; set; }

        [JsonProperty("Case_Id__c", NullValueHandling = NullValueHandling.Ignore)]
        public string CaseIdC { get; set; }

        [JsonProperty("Customer_Ticket_Id__c", NullValueHandling = NullValueHandling.Ignore)]
        public string CustomerTicketIdC { get; set; }

        [JsonProperty("Site__r", NullValueHandling = NullValueHandling.Ignore)]
        public SiteR SiteR { get; set; }

        [JsonProperty("Order__r", NullValueHandling = NullValueHandling.Ignore)]
        public Account OrderR { get; set; }

        [JsonProperty("Status", NullValueHandling = NullValueHandling.Ignore)]
        public string Status { get; set; }

        [JsonProperty("Subject", NullValueHandling = NullValueHandling.Ignore)]
        public string Subject { get; set; }

        [JsonProperty("Order_Name__c", NullValueHandling = NullValueHandling.Ignore)]
        public string OrderNameC { get; set; }

        [JsonProperty("Tech_Service_Type__c", NullValueHandling = NullValueHandling.Ignore)]
        public string TechServiceTypeC { get; set; }

        [JsonProperty("Customer__r", NullValueHandling = NullValueHandling.Ignore)]
        public Account CustomerR { get; set; }

        [JsonProperty("End_Customer__r", NullValueHandling = NullValueHandling.Ignore)]
        public Account EndCustomerR { get; set; }

        [JsonProperty("Name", NullValueHandling = NullValueHandling.Ignore)]
        public string Name { get; set; }

        [JsonProperty("Status__c")]
        public object StatusC { get; set; }

        [JsonProperty("Address__c")]
        public string AddressC { get; set; }

        [JsonProperty("Site_Name__c", NullValueHandling = NullValueHandling.Ignore)]
        public string SiteNameC { get; set; }
    }

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

        [JsonProperty("url")]
        public string Url { get; set; }
    }

我为此进行了很多搜索，但无法找出问题所在。

问题是由SearchAsync的{{1}}方法如何反序列化响应引起的。

客户端尝试将来自服务器的响应反序列化为ForceClient，但是，正如我们在JSON中看到的那样，响应首先包装在List<T>元素中，因此反序列化会引发异常看到。

要解决此问题，您需要执行以下操作：

将searchRecords调用更改为使用SearchAsync类型：

dynamic

将新类型的var response = await client.SearchAsync<dynamic>(query);属性反序列化为searchRecords的数组

SearchRecord

您现在可以使用var records = JsonConvert.DeserializeObject<List<SearchRecord>>(list.searchRecords.ToString());变量来读取从API调用返回的数据。

注意作为参考，我查看了source on GitHub，找到了SearchAsync方法的工作方式，然后查看了测试以了解它们如何从records调用中检索数据。向我显示答案的单元测试代码为here

对象的反序列化产生错误：无法反序列化当前JSON对象？
