c# - 使用 C# 从 Google Translation API 反序列化 JSON

Question

我正在使用 Google Translation API 来检测字符串的语言。 API 返回此 JSON:

{
    "data": {
        "detections": [
            [
                {
                    "confidence": 0.37890625,
                    "isReliable": false,
                    "language": "ro"
                }
            ]
        ]
    }
}

我还没有找到反序列化的方法。我正在使用 System.Runtime.Serialization，这是我的代码:

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

[DataContract]
public class Detection
{
    [DataMember(Name = "confidence")]
    public decimal Confidence { get; set; }

    [DataMember(Name = "isReliable")]
    public bool IsReliable { get; set; }

    [DataMember(Name = "language")]
    public string Language { get; set; }
}
// ...
var jsonSerializer = new DataContractJsonSerializer(typeof(GoogleTranslationResponse));
result = (GoogleTranslationResponse)jsonSerializer.ReadObject( new MemoryStream(Encoding.Unicode.GetBytes(responseData)));

结果是:

Confidence: 0
IsReliable:false
Language:null

在您的 JSON 中，"detections" 的值是一个二维锯齿状数组:

"detections": [ [  { ... } ] ]

因此您的模型需要使用嵌套集合来反射(reflect)这一点:

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