如何将伪JSON数组反序列化为C#

c#arraysjsonjson.netjson-deserialization

3

我可能有点傻，但我卡在了这个问题上。

我正在使用c#编码并尝试将JSON字符串解析为对象。问题在于该字符串包含一个我称之为伪数组的数据字段。它不是真正的数组，因为它缺少[]。

我真的不想创建一个具有500个属性的对象，只是为了迎合我认为是API JSON响应中的错误 - 但是如何将其反序列化为c#对象呢？

以下是API文档页面的示例JSON。(我没有API - 所以我无法更改JSON)

任何建议都将不胜感激。谢谢 k

除了下面的答案之外，您还可以将data反序列化为一个Dictionary<long, Data>。请参见如何解析会导致非法C#标识符的JSON字符串？和从具有ID作为名称的json对象创建强类型的c#对象。 - dbc

你的 JSON 对象的 data 属性是一个关联数组。你需要通过相应的键（在这种情况下是数字字符串）访问每个元素。

// convert from a String into a JObject
var data = JObject.Parse(json);

// access single property
Response.Write(data["data"]["71489"]);
Response.Write(data["data"]["140141"]);

// iterate all properties
foreach (JProperty prop in data["data"])
{
    Response.Write(prop.Name + ": " + prop.Value);

    // Also possible to access things like:
    // - prop.Value["air_by_date"]
    // - prop.Value["cache"]["banner"]
    // - prop.Value["cache"]["poster"]
    // - prop.Value["language"]
}
