c# - 在Gridview中将Json数据抓取到字符串

Question

我正在设置一个网站 ASPX 文件，它可以获取接下来 3 天的天气，输出是 JSON 格式，它们的类太复杂了，我无法理解。如果我想只提取接下来 3 天的天气，我该怎么做呢？

https://samples.openweathermap.org/data/2.5/forecast?q=London,us&appid=b6907d289e10d714a6e88b30761fae22

这是顶部显示的 JSON 输出。

What I'm trying to accomplish is to extract the next 3 days of the weather "Description" and put it to a GridView.我已经使用 JSON 美化器来获取类，但我仍然感到困惑。

任何帮助，将不胜感激

这是我当前的代码，我被困在这里

   protected void Button1_Click(object sender, EventArgs e)
    {
        string searchTerm = TextBox1.Text;

        var webRequest = (HttpWebRequest)WebRequest.Create("https://samples.openweathermap.org/data/2.5/forecast?q=" + Server.UrlEncode(searchTerm) + "&units=metric&APPID=b6907d289e10d714a6e88b30761fae22");

        var webResponse = (HttpWebResponse)webRequest.GetResponse();

        if (webResponse.StatusCode == HttpStatusCode.OK)
        {

            Label1.Text = "The Next 3 days of weather in your area in" + searchTerm + " .";
            JavaScriptSerializer json = new JavaScriptSerializer();
            StreamReader sr = new StreamReader(webResponse.GetResponseStream());
            string resString = sr.ReadToEnd();
            });

            GridView1.DataSource = ?;
            GridView1.DataBind();
        }
        else
            Label.Text = "Invalid Response";
    }
