如何反序列化 JSON 并在 C# 中获取值

Question

// Get the JSON response.                    string contentString = await response.Content.ReadAsStringAsync();                    Console.WriteLine(contentString);                    var rs = Newtonsoft.Json.Linq.JToken.Parse(contentString); Result rst = JsonConvert.DeserializeObject<Result>(contentString);//Here i need to get the first value in the description as it appears to be a listvar firstValue= rst.description;//And also a value from captionvar captionValue = rst.Caption public class Result    {        public Category[] categories { get; set; }        public Description description { get; set; }        public string requestId { get; set; }        public  Caption caption { get; set;}        public Metadata metadata { get; set; }        public Color color { get; set; }    }    public class Description    {        public string[] tags { get; set; }        public Caption[] captions { get; set; }    }    public class Caption    {        public string text { get; set; }        public float confidence { get; set; }    }    public class Metadata    {        public int width { get; set; }        public int height { get; set; }        public string format { get; set; }    }    public class Color    {        public string dominantColorForeground { get; set; }        public string dominantColorBackground { get; set; }        public string[] dominantColors { get; set; }        public string accentColor { get; set; }        public bool isBWImg { get; set; }    }    public class Category    {        public string name { get; set; }        public float score { get; set; }    }} 我明白我想要的很简单，但对我来说看起来有点复杂。我已经使用了Result //rst = JsonConvert.DeserializeObject<Result>(contentString);连接并获取响应，我已经传入了 JSON 数据的 contentString。我只想得到我想要的价值。使用 description 作为示例会更有帮助。谢谢
