Question

我需要从下面的JSON中获取值，例如如何在Info中索引Id？

整个JSON由许多匹配组成，这只是一个Id 5aa891cd1e1422452e8b4567，这是一个匹配的结构。

我尝试：

var jsonDATA = JObject.Parse(data);

foreach (var e in jsonDATA["events"]) {
    //in this step, the result is JSON below
    var id = e["info"]["id"];` // error: cannot access child value on newtonsoft json linq jproperty
}

有什么想法吗？

{"5aa891cd1e1422452e8b4567": {
      "info": {
        "id": "5aa891cd1e1422452e8b4567",

您可以对此类数据使用匿名类型deserialization。希望它有效。

//using Newtonsoft.Json;
var jsonData = JsonConvert.DeserializeAnonymousType(
    data,
    new 
    {
      events = new[]
      {
        new
        { 
          Id = new { info = "", stats = "", away = "", odds = "" }
        }
      }
  );            

foreach(var item in jsonData.events)
{
    var id=item.info.id; // getting id present in info
}
