【问题描述】：

我无法将此 json 对象加载到数组中。

这是我从 API 获得的 JSON 响应的 sn-p（片段）：

   "count":192,
   "value":[
      
         "id":"03dd9f56-108f-4e8f-b92e-93df05717464",
         "name":"IIBTest",
         "url":"https://devops.com/tfs/DefaultCollection/_apis/projects/03dd9f56-108f-4e8f-b92e-93df05717464",
         "state":"wellFormed",
         "revision":14434848,
         "visibility":"private",
         "lastUpdateTime":"2016-08-19T12:21:37.187Z"
      ,
      
         "id":"b7e15034-fc8f-4f7e-866a-cb06f44b12ed",
         "name":"MS Project POC",
         "description":"POC for MS Project with TFS",
         "url":"https://devops.com/tfs/DefaultCollection/_apis/projects/b7e15034-fc8f-4f7e-866a-cb06f44b12ed",
         "state":"wellFormed",

         "name":"WorkflowReporting",
         "url":"https://devops.com/tfs/DefaultCollection/_apis/projects/59e06621-c5f5-4fd1-9c55-1def541b99d9",
         "state":"wellFormed",
         "revision":14434591,
         "visibility":"private",
         "lastUpdateTime":"2015-09-11T06:59:12.21Z"
      ,
      
         "id":"78a802f0-5eee-4bcb-bde9-a764e46f56db",
         "name":"iSolutions",
         "description":"",
         "url":"https://devops.com/tfs/DefaultCollection/_apis/projects/78a802f0-5eee-4bcb-bde9-a764e46f56db",
         "state":"wellFormed",
         "revision":14435476,
         "visibility":"private",
         "lastUpdateTime":"2021-08-05T17:17:26.193Z"
      ,
      
         "id":"1f20506a-63a5-486a-a857-fec64d7486a6",
         "name":"Training",
         "description":"MLITS Training and Learning",
         "url":"https://devops.com/tfs/DefaultCollection/_apis/projects/1f20506a-63a5-486a-a857-fec64d7486a6",
         "state":"wellFormed",
         "revision":14435350,
         "visibility":"private",
         "lastUpdateTime":"2021-04-08T22:48:02.923Z"
      ,
      ...

这是我的代码：

public class Rootobject

    public int count  get; set; 
    public Value[] value  get; set; 


public class Value

    public string id  get; set; 
    public string name  get; set; 
    public string url  get; set; 
    public string state  get; set; 
    public int revision  get; set; 
    public string visibility  get; set; 
    public DateTime lastUpdateTime  get; set; 
    public string description  get; set; 

static void Main(string[] args)

    var client = new RestClient("https://devops.americannational.com/tfs/defaultcollection/_apis/projects?$top=300&api-version=5.0")
    
        Authenticator = new RestSharp.Authenticators.NtlmAuthenticator()
    ;

    client.Timeout = -1;
    var request = new RestRequest(Method.GET);
    IRestResponse response = client.Execute(request);
    var jsonString = response.Content;
    var jo = JObject.Parse(jsonString);
    //...

        

我想将项目的名称加载到数组中，以便以后可以遍历它们。任何帮助表示赞赏，我已经尝试了一些东西，但运气不佳。

【问题讨论】：

你试过GetAsync<Rootobject>()而不是client.Execute吗？ RestSharp 文档：restsharp.dev/getting-started/…

运行时会发生什么？是否抛出异常？如果是这样，请将异常详细信息添加到您的问题中。

你得到成功的HTTP响应码了吗？

【参考方案1】：

你可以使用 var jo = JsonConvert.DeserializeObject<Rootobject>(jsonString);

然后遍历jo.value

@ShahramH.Farmanesh 如果您认为这是正确的答案，请为帖子的作者点赞。

【参考方案2】：

试试这个

var jsonDeserialized= JsonConvert.DeserializeObject<Rootobject>(json);

作为示例如何使用它，此查询返回项目名称数组

var projectNames= jsonDeserialized.value.Select(v => v.name ).ToArray();

输出

["IIBTest","MS Project POC","WorkflowReporting","iSolutions","Training"]

这会返回一个项目列表

var projects= jsonDeserialized.value.ToList();

谢谢你这个作品，虽然我不明白这部分，（v => v.name）。你能解释一下吗？

@ShaneP 我只是在创建项目名称列表。查看我的更新答案
