Question

Json看起来像：

 [{"id":"001788fffe2e6479","internalipaddress":"192.168.1.2"}]

我的反序列化C＃代码（使用Newtonsoft）：

        public class ipBridge
    {
        public string Id { get; set; }
        public string InternalIpAddress { get; set; }
        public string MacAddress { get; set; }
    }

    public class LocatedBridge
    {
        public string BridgeId { get; set; }
        public string IpAddress { get; set; }
    }

和：

        var request = (HttpWebRequest)WebRequest.Create("https://www.test.com/api"); 

        var response = (HttpWebResponse)request.GetResponse();

        var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();


        ipBridge[] responseModel = JsonConvert.DeserializeObject<ipBridge[]>(responseString); //responseString = [{"id":"001788fffe2e6479","internalipaddress":"192.168.1.2"}]

        responseModel.Select(x => new LocatedBridge() { BridgeId = x.Id, IpAddress = x.InternalIpAddress }).ToList();

        Console.WriteLine($"{ip}"); // ip = internalipaddress of JSON, HOW?

Answer 1

您有有效的反序列化代码，而问题实际上与它无关。您要访问的是反序列化的对象字段。

ipBridge[] responseModel = JsonConvert.DeserializeObject<ipBridge[]>(responseString); 
var locatedBridgeModel = responseModel.Select(x => new LocatedBridge() { BridgeId = x.Id, IpAddress = x.InternalIpAddress }).ToList();

Console.WriteLine($"{responseModel[0].InternalIpAddress}"); 
//or
Console.WriteLine($"{locatedBridgeModel[0].IpAddress}"); 
//or
Console.WriteLine($"{locatedBridgeModel.First().IpAddress}");

Answer 2

从ipBridge，[（方括号）的出现看来，您的JSON中有]个对象（基于JSON中使用的名称），我可以告诉它是这些对象的列表。因此，应将其反序列化为List<ipBridge>。

使用此代码：

var json = @"[{ ""id"":""001788fffe2e6479"",""internalipaddress"":""192.168.1.2""}]";
var deserialized = JsonConvert.DeserializeObject<List<ipBridge>>(json);

反序列化JSON-如何反序列化此JSON？
