c# - 如何将具有动态根名称的 json 转换为 C# 列表

Question

var stringResult = await HttpHelper.PostAsync(batchUrl, content);

调用上面的行后，我在上面的 stringResult 变量中得到以下结果作为 C# 中的 API 响应。我想将下面的“Items”值转换为 C# 列表。在每个结果中，第一个 GUID 都是不同的。如何将以下结果转换为 C# 列表。我只想要元素。

{
    "0934009e-6518-4440-91e3-c252d2e2cc4f": {
        "Status": 200,
        "Headers": {
            "Content-Type": "application/json; charset=utf-8"
        },
        "Content": {
            "Items": [{
                    "Timestamp": "2021-10-18T14:00:00Z",
                    "Value": 20.7,
                    "UnitsAbbreviation": "ppm"
                }, {
                    "Timestamp": "2021-10-25T14:00:00Z",
                    "Value": 15.9,
                    "UnitsAbbreviation": "ppm"
                }, {
                    "Timestamp": "2021-11-01T14:00:00Z",
                    "Value": 14.8,
                    "UnitsAbbreviation": "ppm"
                }, {
                    "Timestamp": "2021-11-08T15:00:00Z",
                    "Value": 20.1,
                    "UnitsAbbreviation": "ppm"
                }, {

                    "Value": 19.5,
                    "UnitsAbbreviation": "ppm"
                }, {

                    "Value": 19.7,
                    "UnitsAbbreviation": "ppm"
                }, {
                    "Timestamp": "2021-11-29T15:00:00Z",
                    "Value": 20.4,
                    "UnitsAbbreviation": "ppm"
                }
            ]
        }

当json结构的某些部分未知时，您需要手动探索它。有多种方法可以做到这一点，但我习惯于传递 JObject :

var root = JObject.Parse(text);
// Unknown name property, then iterate
// When the object has one property, First is a good fit
var response = root.First as JProperty;
var guid = response.Name;
var itemsJson = response.Value["Content"]["Items"];
var items = itemsJson.ToObject<List<Item>>();
