}

我在“项目”中每个新项目都有一个新名称的那一刻感到困惑。目前这就是我所拥有的：

   public class 7Days
{
    public string median_price { get; set; }
    public string median_net_price { get; set; }
    public string average_price { get; set; }
    public string average_net_price { get; set; }
    public string lowest_price { get; set; }
    public string lowest_net_price { get; set; }
    public string highest_price { get; set; }
    public string highest_net_price { get; set; }
    public string mean_absolute_deviation { get; set; }
    public double deviation_percentage { get; set; }
    public double trend { get; set; }
    public int volume { get; set; }
}

public class 30Days
{
    public string median_price { get; set; }
    public string median_net_price { get; set; }
    public string average_price { get; set; }
    public string average_net_price { get; set; }
    public string lowest_price { get; set; }
    public string lowest_net_price { get; set; }
    public string highest_price { get; set; }
    public string highest_net_price { get; set; }
    public string mean_absolute_deviation { get; set; }
    public double deviation_percentage { get; set; }
    public double trend { get; set; }
    public int volume { get; set; }
}

public class AllTime
{
    public string median_price { get; set; }
    public string median_net_price { get; set; }
    public string average_price { get; set; }
    public string average_net_price { get; set; }
    public string lowest_price { get; set; }
    public string lowest_net_price { get; set; }
    public string highest_price { get; set; }
    public string highest_net_price { get; set; }
    public string mean_absolute_deviation { get; set; }
    public double deviation_percentage { get; set; }
    public double trend { get; set; }
    public int volume { get; set; }
}

public class Bayonet
{
    public string name { get; set; }
    public string safe_price { get; set; }
    public string safe_net_price { get; set; }
    public bool ongoing_price_manipulation { get; set; }
    public int total_volume { get; set; }
    public 7Days 7_days { get; set; }
    public 30Days 30_days { get; set; }
    public AllTime all_time { get; set; }
    public int first_seen { get; set; }
}

public class BayonetBrightWaterBattleScarred
{
    public string name { get; set; }
    public string safe_price { get; set; }
    public string safe_net_price { get; set; }
    public bool ongoing_price_manipulation { get; set; }
    public int total_volume { get; set; }
    public  7_days { get; set; }
    public  30_days { get; set; }
    public  all_time { get; set; }
    public int first_seen { get; set; }
}

public class XM1014VariCamoBlueWellWorn
{
    public string name { get; set; }
    public string safe_price { get; set; }
    public string safe_net_price { get; set; }
    public bool ongoing_price_manipulation { get; set; }
    public int total_volume { get; set; }
    public  7_days { get; set; }
    public  30_days { get; set; }
    public  all_time { get; set; }
    public int first_seen { get; set; }
}

public class Items
{
    public Bayonet ★ Bayonet { get; set; }
    public BayonetBrightWaterBattleScarred ★ Bayonet | Bright Water (Battle-Scarred) { get; set; }
    public XM1014VariCamoBlueWellWorn XM1014 | VariCamo Blue (Well-Worn) { get; set; }
}

public class Example
{
    public bool success { get; set; }
    public Items items { get; set; }
    public int build_time { get; set; }
    public int updated_at { get; set; }
}

但是我需要在有很多不同名称的项目的地方反序列化 json，告诉我如何避免使用每个项目名称创建类？祝大家新年快乐）））

UPD。我重做了课程，这就是发生的事情：

{
public class _7Days
{
public string median_price { get; set; }
public string median_net_price { get; set; }
public string average_price { get; set; }
public string average_net_price { get; set; }
public string lowest_price { get; set; }
public string lowest_net_price { get; set; }
public string highest_price { get; set; }
public string highest_net_price { get; set; }
public string mean_absolute_deviation { get; set; }
public double deviation_percentage { get; set; }
public double trend { get; set; }
public int volume { get; set; }
}

public class _30Days
{
public string median_price { get; set; }
public string median_net_price { get; set; }
public string average_price { get; set; }
public string average_net_price { get; set; }
public string lowest_price { get; set; }
public string lowest_net_price { get; set; }
public string highest_price { get; set; }
public string highest_net_price { get; set; }
public string mean_absolute_deviation { get; set; }
public double deviation_percentage { get; set; }
public double trend { get; set; }
public int volume { get; set; }
}

public class _AllTime
{
public string median_price { get; set; }
public string median_net_price { get; set; }
public string average_price { get; set; }
public string average_net_price { get; set; }
public string lowest_price { get; set; }
public string lowest_net_price { get; set; }
public string highest_price { get; set; }
public string highest_net_price { get; set; }
public string mean_absolute_deviation { get; set; }
public double deviation_percentage { get; set; }
public double trend { get; set; }
public int volume { get; set; }
}

public class Item
{
public string name { get; set; }
public string safe_price { get; set; }
public string safe_net_price { get; set; }
public bool ongoing_price_manipulation { get; set; }
public int total_volume { get; set; }
public _AllTime all_time { get; set; }
public _7Days _7_days { get; set; }
public _30Days _30_days { get; set; }


public int first_seen { get; set; }
}

public class Rootobject
{
public bool success { get; set; }
public Dictionary<string, Item> item { get; set; }
public int build_time { get; set; }
public int updated_at { get; set; }
}
}

创建了一个读取 json 的附加类：

public static Rootobject GetRoot()
    {
        string path = @"C:\Users\DB.json";
        StreamReader sr = new StreamReader(path);
        string itemDB = sr.ReadToEnd();
        return JsonConvert.DeserializeObject<Rootobject>(itemDB);                

    }

在我的程序中，我调用：

Rootobject itemsDB = PricerApi.GetRoot();

但是在 itemsDB 的 item=null 字段中，虽然从文件中读取并执行反序列化时，所有项目都存在于 item 字段中，我打开并查看它们，一切都与 json 中应有的完全一样，我做了什么错误的？
