我正在使用C＃而无法弄清楚如何构造类结构以获取提取的Quote对象列表。这是我试过的：
public class Container
{
[JsonProperty("query")]
public Query Data { get; set; }
}
public class Query
{
[JsonProperty("count")]
public int Count { get; set; }
[JsonProperty("created")]
public DateTime Created { get; set; }
[JsonProperty("lang")]
public string Lang { get; set; }
[JsonProperty("results")]
public List Results { get; set; }
}
public class Quote
{
[JsonProperty("symbol")]
public string Symbol { get; set; }
[JsonProperty("Ask")]
public string Ask { get; set; }
[JsonProperty("AverageDailyVolume")]
public string AverageDailyVolume { get; set; }
}
答案 0 :(得分：1)
不知道这对你现在是否有帮助，但你的问题是你的json不符合你的对象模型。要使用包含结果列表的Query对象反序列化回Container对象，结果json应如下所示：
"results": [
{
"symbol": "UAM",
"Ask": null,
"AverageDailyVolume": "262683"
},
{
"symbol": "WCG",
"Ask": null,
"AverageDailyVolume": "898853"
},
{
"symbol": "WLP",
"Ask": null,
"AverageDailyVolume": "2976430"
}
]
但你的json看起来像这样：
"results":{
"quote":[
{
"symbol":"UAM",
"Ask":null,
"AverageDailyVolume":"262683",
}
]
}
“quote”属性正在弄乱它。因此，为了映射这个，您必须更改源json或实现某种具有属性“quote”的自定义列表....或者您手动反序列化它。但原生json会将对象展开为
{
...Some object
}
而不是：
"myobject" : {
...Some object.
}
在集合内。
