使用C＃從Google Translation API反序列化JSON

Question

我正在使用Google Translation API來檢測字符串的語言。 API返回此JSON：

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

我還沒有找到反序列化的方法。 我正在使用System.Runtime.Serialization ，這是我的代碼：

[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)));

我得到了這個結果：

Confidence: 0
IsReliable:false
Language:null

在您的JSON中， "detections"的值是一個2d鋸齒狀數組：

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

因此，您的模型需要通過使用嵌套集合來反映這一點：

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