C#正在寻找如何反序列化此类json的帮助

首先，我是个初学者。我一直在寻找类似于这个问题的东西，但没有设法解决这个问题。现在我已经被这个问题困扰了一段时间。我使用的API来自我们本地的post delivery，在这里我们可以通过json链接获取信息，如deliverytime、address等。但在本例中，json看起来有点不同，我不知道如何使用它

如果有人能向我解释我如何访问数据，如deliverdate和address，我会非常高兴。现在当我尝试时，它只显示值为null

我使用json.net进行反序列化

下面你可以看到它的样子

private async void button_Click(object sender, RoutedEventArgs e)
{
    string url = "https://api2.postnord.com/rest/shipment/v1/trackandtrace/findByIdentifier.json?id=...";

    HttpClient client = new HttpClient(); 
    string date = await client.GetStringAsync(new Uri(url));
    var jarray = JsonConvert.DeserializeObject<Rootobject>(date);
}

这里有一个现有的帖子可能会对你有所帮助

这里有一些关于Newtonsoft的信息

用法示例：

Newtonsoft.Json.JsonConvert.DeserializeObject()

你可以试试看

var jarray = JsonConvert.DeserializeObject<Rootobject>(date, 
  new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-ddTHH:mm:ss" });

var jarray=JsonConvert.DeserializeObject（日期，
新的IsoDateTimeConverter{DateTimeFormat=“yyyy-MM-ddTHH:MM:ss”}）；

与其他答案状态一样，

JsonConvert.DeserializeObject（）

是您需要的方法。之后，您只需要遍历反序列化的数据结构

至于为什么在尝试反序列化之后会得到NULL，如果反序列化失败，则返回NULL。通常，当数据格式不正确或字符大小写不匹配时。但是对于您提供的示例JSON，我使用您的类正确地反序列化了它

Rootobject root = JsonConvert.DeserializeObject<Rootobject>(data);
if (root == null ||
    root.TrackingInformationResponse == null ||
    root.TrackingInformationResponse.shipments == null ||
    root.TrackingInformationResponse.shipments.Length == 0)
{
    throw new Exception();
}
Shipment shipment = root.TrackingInformationResponse.shipments[0];

if (shipment.consignee == null || shipment.consignee.address == null)
{
    throw new Exception();
}

Console.WriteLine("Consignee: {0}", shipment.consignee);
Console.WriteLine("Estimated Time of Arrival: {0}", shipment.estimatedTimeOfArrival);

Rootobject root=JsonConvert.DeserializeObject（数据）；
if（root==null）||
root.TrackingInformationResponse==null||
root.TrackingInformationResponse.Shippings==null||
root.TrackingInformationResponse.Shippings.Length==0）
{
抛出新异常（）；
}
Shipping Shipping=root.TrackingInformationResponse.Shipping[0]；
if（shipping.delegator==null | | shipping.delegator.address==null）
{
抛出新异常（）；
}
Console.WriteLine（“收货人：{0}”，shipping.delegate）；
Console.WriteLine（“预计到达时间：{0}”，Shipping.estimatedTimeOfArrival）；

大家好。有人能让我理解公共类Rootobject{public Trackinginformationresponse Trackinginformationresponse{get；set；}}公共类Trackinginformationresponse{public-shipping[]shippings{get；set；}请发布你得到的JSON字符串，这样我们可以看到反序列化的输入是什么。嗨，这是信息的样子。我想从中得到的是收货人的信息和估计到达时间。是的，Newtonsoft.JSON是非常感谢你的方法。我不明白我必须要Rootobject root=JsonConvert.DeserializeObject（数据）；Shipping Shipping=root.TrackingInformationResponse.Shippings[0]；但现在似乎要显示数据了！您好，如果我想使用类Shipping中的项[]，您有没有办法向我解释一下该怎么做？因为它是一个数组，我现在无法在文本框中显示它？
