【问题描述】：

我是销售人员的新手。我正在尝试从我的 .Net Core Web API 调用我的销售人员 API。

使用下面的代码：

 string new_Contact_url = "some URL";
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new_Contact_url);
                request.Method = "GET";
                request.Headers.Add("Authorization", "Bearer 00D0E00000019dU!AQUAQK7Mcfutr7Y03dsuuKy9wyMt.GzRCUve6Rll8tDr2APzuHE.J2UjXXYt1vNPiQB5Fn2BCvoC7PwEwN9OLuyTbvTAp8Dj");
                request.ContentType = "application/json; charset=utf-8";
                ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
                WebResponse response = request.GetResponse();
                Stream dataStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream);
                var resp = reader.ReadToEnd();
                var obj = JsonConvert.DeserializeObject(resp);
                //inplace of object I want to convert this into List<AccountDetail>
                //List<AccountDetail>

通过在命令提示符中使用 Curl 命令，我得到这个响应为 json

      "recordTypeInfo" : null
     ]
  

我从这个回复中了解到，这里面有很多元数据信息。 我希望从响应中得到的重要部分是记录标签

我从记录标签创建了等效 C# 类

public class AccountDetail
    

        public string Etag  get; set; 
        public string CreatedDate  get; set; 
        public string Id  get; set; 
        public string LastModifiedDate  get; set; 
        public string Name  get; set; 
        public string ApiName  get; set; 

        public List<OwnerDetails> Owners  get; set; 
    

    public class OwnerDetails
    
        public string Id  get; set; 
        public string FirstName  get; set; 
        public string LastName  get; set; 
        public string ApiName  get; set; 

    

那么我如何从记录标签中提取信息到等效的 C# 对象列表中。这一行 var obj = (List)JsonConvert.DeserializeObject(resp);

【问题讨论】：

您需要确保正确匹配类型。例如：Owners 是请求正文中的一个对象，但您将其作为类型 List<T>。另外，您是否考虑过在属性上使用 [JsonProperty()] 属性来帮助将它们正确映射到您的类？尝试使用这个website to generate your c# classes from json

你需要什么记录标签？ （粗体）。抱歉，我没听懂

@MarkC。您能否为此发布一个示例，我以前没有使用过 JSONProperty。另外，我的理解是 Owners 是一个嵌套对象，所以我为它创建了一个单独的类，并在 Account details 中将其引用为 List。

@Prany 在我粘贴的大JSON中有一个函数指针记录：里面有一个属性记录：我需要提取这个值并将其填充到一个c#对象中

【参考方案1】：

你可以使用 Newtonsoft.Json

var files = JObject.Parse(YourJSON);
var recList = files.SelectTokens("$..records..records").ToList();
foreach (JObject obj in recList.Children())
 
   foreach (JProperty prop in obj.Children())
      
        var key = prop.Name.ToString();
        var value = prop.Value.ToString();
         //Do your stuffs here
      

  

【讨论】：

感谢 Prany，这正是我提取值所需要的。

【参考方案2】：

JsonConverter可以帮助你实现你所需要的。只需使用填充对象属性的所有必需规则为您的类实现转换器，并将其用于反序列化，例如：

List<AccountDetail> accountDetails = JsonConvert.DeserializeObject<List<AccountDetail>>(json, new ListOfAccountDetailsJsonConverter(typeof(List<AccountDetail>)));
