C# 解析 Json - System.Runtime.Serialization.Json

Question

我正在使用 System.Runtime.Serialization.Json 库

这不起作用

public class Detections
            {
                [DataContract]
                public class RootObject
                {
                    [DataMember(Name = "data")]
                    public DataObject Data { get; set; }
                }

                [DataContract]
                public class DataObject
                {
                    [DataMember(Name = "detections")]
                    public List<Detection> Detections { get; set; }
                }

                [DataContract]
                public class Detection
                {
                    [DataMember(Name = "language")]
                    public string Language { get; set; }
                    [DataMember(Name = "isReliable")]
                    public string IsReliable { get; set; }
                    [DataMember(Name = "confidence")]
                    public string Confidence { get; set; }
                }
            }

那么我应该如何解析它

{
     "data": {
      "detections": [
       [
        {
         "language": "tr",
         "isReliable": false,
         "confidence": 0.086520955
        }
       ]
      ]
     }
    }

出现此问题的原因有两个。

1) 需要从Detections 类中删除您的嵌套类。

2) JSON 包含一个用于检测成员的多维数组，我认为它需要是单一的。

我已经测试了下面详细的代码，它工作正常。

//Classes

[DataContract]
public class RootObject
{
    [DataMember(Name = "data")]
    public DataObject Data { get; set; }
}

[DataContract]
public class DataObject
{
    [DataMember(Name = "detections")]
    public List<Detection> Detections { get; set; }
}

[DataContract]
public class Detection
{
    [DataMember(Name = "language")]
    public string Language { get; set; }
    [DataMember(Name = "isReliable")]
    public string IsReliable { get; set; }
    [DataMember(Name = "confidence")]
    public string Confidence { get; set; }
}

//Code to deserialize

var serializer = new DataContractJsonSerializer(typeof(RootObject));
var json = "{\"data\": {\"detections\": [{\"language\": \"tr\",\"isReliable\": false,\"confidence\": 0.086520955}]}}";
var stream = new MemoryStream(Encoding.UTF8.GetBytes(json));
var rootObject = serializer.ReadObject(stream);
stream.Close();

我希望这对你有帮助。

Answer 2

在你的 json 中，“Detection”是一个列表列表。请注意，jdavies 的答案不承认这一点。

[DataContract]
public class DataObject
{
[DataMember(Name = "detections")]
public List<List<Detection>> Detections { get; set; }
}

Answer 3

除了 Detections 是集合的集合之外，一切都是正确的。我不知道为什么会这样，但它对我有用。

[DataContract]
public class DataObject
{
    [DataMember(Name = "detections")]
    public List<List<Detection>> Detections { get; set; }
}
