您有一個 json 符合DateTime和List<Item>的字典。 您可以使用以下內容反序列化您的 Json

public class Item
{
    public int Duration { get; set; }
    public string End { get; set; }
    public string Start { get; set; }
}

// and in main,
var obj = JsonConvert.DeserializeObject<Dictionary<DateTime, List<Item>>>(json);

// Use TryGetValue to look up values of a specific Key 
obj.TryGetValue(DateTime.Parse("8/27/2020"), out List<Item> items);
Console.WriteLine(string.Join(", ", items.Select(x => x.Duration)));

// prints
424, 366
