c# - JSON は JSON 配列を型にデシリアライズできません

Question

複数のアプローチを試した後でも、この JSON を逆シリアル化しようとすると問題が発生し続けます。

以下は、Web サービスによって返される JSON です。

非常に醜い私は知っています。残念ながら、それは他人の Web サービスであるため、私にできることはあまりありません。私は C# モデルクラスをいじっていますが、うまく機能していないようです。

モデルクラス:

[JsonObject(MemberSerialization.OptIn)]
public class BibleGatewayVerse
{
    [JsonProperty("osis")]
    public string Reference { get; set; }
    [JsonProperty("content")]
    public string Content { get; set; }
    [JsonProperty("footnotes")]
    public List<string> Footnotes { get; set; }
    [JsonProperty("crossrefs")]
    public List<string> CrossReferences { get; set; }
}

[JsonObject(MemberSerialization.OptIn)]
public class BibleGatewayVerses
{
    [JsonProperty("data")]
    public List<BibleGatewayVerse> Verses;
}

私は json2csharp.com などのツールを使用しましたが、それらは同じものを生成します。List の代わりに配列を使用することも試しましたが、役に立ちませんでした。さらに、脚注リストを型オブジェクトに置き換えてみました (json2sharp の推奨に従って)。

どんな助けでも大歓迎です。

Json データは配列にラップされているため、型の配列に逆シリアル化する必要があります

JsonConvert.DeserializeObject<BibleGatewayVerses[]>(jsonData);

お役に立てれば

このようにフォローすればいいと思います

public class BibleGatewayVerse
{

    [JsonProperty("data")]
    public Datum[] Data { get; set; }
}


public class Datum
{

    [JsonProperty("osis")]
    public string Osis { get; set; }

    [JsonProperty("content")]
    public string Content { get; set; }

    [JsonProperty("footnotes")]
    public object[] Footnotes { get; set; }

    [JsonProperty("crossrefs")]
    public string[] Crossrefs { get; set; }
}
