【问题描述】：
我想从“scanEvents”列表或数组中提取值。每个 scanEvent 都有一个日期、事件类型、事件描述、派生状态等...
我已经使用了几种方法，例如下面的这个，但到目前为止我无法提取每个“scanEvent”的值
var data = (JObject)JsonConvert.DeserializeObject(strFedExJSON);
var scanevents = data["scanEvents"];
var output = scanevents.Children<JProperty>()
.Select(prop => prop.Value.ToObject<Scanevent>())
.ToList();
foreach (var x in output)
{
richTextBox1.Text += output + Environment.NewLine;
}
我想在下面得到这种输出：
"date": "2021-12-22T15:14:00-10:00", "eventDescription": "Delivered", "city": "HILO", "stateOrProvinceCode": "HI", "countryCode": "US", "locationType": "DELIVERY_LOCATION", "derivedStatus": "Delivered"
"date": "2021-12-22T14:40:00-10:00", "eventDescription": "On FedEx vehicle for delivery", "city": "HILO","stateOrProvinceCode": "HI","countryCode": "US", "locationType": "VEHICLE", "derivedStatus": "In transit"
"date": "2021-12-22T14:37:00-10:00","eventDescription": "At local FedEx facility","city": "countryCode": "US","HILO", "locationType": "DESTINATION_FEDEX_FACILITY", "derivedStatus": "In transit"
如何提取下面“scanEvents”列表中每个事件的值（日期、事件描述、派生状态）？这个似乎被埋在了几种类型或对象之下。

【问题讨论】：

在我看来，当 json 包含多个 trackResults 时，您可能有多个 scanEvents。所以没有明确的路径。最后的输出应该包含 trackingNumber，这样你就知道在这种情况下事件属于哪里。我要做的是创建真正的类来将 json 序列化为（使用 json 到类转换器）。这在代码中更容易理解，并且您可以更轻松地在类树中导航并从中创建有意义的输出字符串。
-
你可以考虑自动创建一个类，它可以让你循环遍历它的 stronly 类型属性；见stackoverflow.com/a/48023576/4180382
