C#- 需要从我的动态对象访问 JSON 数据值

Question

我有一个json数据如下-

{
    "request": {
        "type": "",
        "query": "",
        "language": "en",
        "unit": "m"
    },
    "location": {
        "name": "",
        "country": "",
        "region": "",
        "lat": "",
        "lon": "",
        "timezone_id": "Asia/Kolkata",
        "localtime": "2020-05-29 23:30",
        "localtime_epoch": 1590795000,
        "utc_offset": "5.50"
    },
    "current": {
        "observation_time": "06:00 PM",
        "temperature": 40,
        "weather_code": 116,
        "weather_icons": [
            ""
        ],
        "weather_descriptions": [
            "Partly cloudy"
        ],
        "wind_speed": 9,
        "wind_degree": 230,
        "wind_dir": "SW",
        "pressure": 1006,
        "precip": 0,
        "humidity": 26,
        "cloudcover": 25,
        "feelslike": 42,
        "uv_index": 1,
        "visibility": 6,
        "is_day": "no"
    },
    "forecast": {
        "2020-05-28": {
            "date": "2020-05-28",
            "date_epoch": 1590624000,
            "astro": {
                "sunrise": "05:41 AM",
                "sunset": "06:46 PM",
                "moonrise": "10:29 AM",
                "moonset": "11:48 PM",
                "moon_phase": "First Quarter",
                "moon_illumination": 39
            },
            "mintemp": 32,
            "maxtemp": 44,
            "avgtemp": 38,
            "totalsnow": 0,
            "sunhour": 13.1,
            "uv_index": 9
        }
    }
}

前三个节点（“请求”，“位置”，“当前”）正确绑定，但用于“预测”，因为第一个节点是日期时间。我是这样写的-

var dataObjects = JsonConvert.DeserializeObject<Location_Weather.Weather>(customerJsonString);                   
var dataObjects23 = JsonConvert.DeserializeObject<Dictionary<string, dynamic>> (customerJsonString);
dynamic forecast_details = dataObjects23["forecast"];

现在的问题是我无法获取这些值。 我需要一些关于如何将这个值从 forecast_details 动态对象获取到我的 C# 代码中的指导。 下面是我需要在我的 c# 代码中访问它们的值的屏幕截图

在调试动态对象时，我在结果视图中找到了这些值。但我不确定如何在我的 c# 代码中访问这些值。

请告诉我如何从我的 C# 动态对象（forecast_details）中获取这些值。

看看这个问题，有两个答案可以帮到你。

How to add properties at runtime to JSON (C#)

您可以将 forecast json 解析为 JObject，并使用 foreach 从中获取所有值。

Answer 2

这是我想出来的。希望对其他人有所帮助。

JObject obj = JObject.Parse(customerJsonString);
var forecast_details = obj.SelectToken("forecast").Children().OfType<JProperty>()
                                    .ToDictionary(p => p.Name, p => new
                                    {
                                        MaxTemp = (int)p.First()["maxtemp"],
                                        MinTemp = (int)p.First()["mintemp"]
                                    });
if(forecast_details.Count>0)
{
  int max_temp = forecast_details.Values.Select(x => x.MaxTemp).FirstOrDefault();
  int min_temp = forecast_details.Values.Select(x => x.MinTemp).FirstOrDefault();
}
