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

本文关键字：Json Runtime Serialization System Parse | 更新日期: 2023-09-27 18:06:07

我正在使用system . runtime . serialize . json库

这行不通

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; }
                }
            }

我该如何解析这个

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

出现这个问题有两个原因。

1)你的嵌套类需要从Detections类中移除。

2) JSON包含检测成员的多维数组，我假设它需要是单个的。

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();

在json中"Detection"是一个列表的列表。请注意，jdavies的回答不承认这个

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

一切都是正确的，除了Detections是集合的集合。我不知道为什么会这样，但它对我很有效。

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