Deserialize a JSON file which contains an Array

I'm trying to deserialize a JSON file but I'm currently stuck because of the Array "statistics".

My JSON file looks like this:

[
  {
    "name": "itemName",
    "level": 8,
    "imgUrl": "https://imgItemName.png",
    "description": "itemDescription.",
    "statistics": [
    {
        "Vitality": {
          "min": 10,
          "max": 13
        }
    }
    ]
  }
]

My classes look like this:

public class Item
{
  public string name;
  public int level;
  public string type;
  public string imgUrl;
  public string description;
  public List<Statistics>statistics;
  //public List<JArray> statistics;
  //public Statistics[] statistics;
  
}

public class Statistics
{
  public string Vitality;
  public List<MinMax> minmax;
  //public MinMax[] minMax;
}

public class MinMax
{
  public string min;
  public string max;
}

And this is how I'm trying to deseralize the file:

string json = System.IO.File.ReadAllText("items.json");
var listItems = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Item>>(json);

I have already tried many combinations but cannot recover the Statistics key in any case. Any help will be really appreciated :)

If you are using Visual studio you can generate the C# classes bazed on Json by going to Edit-> paste special -> Paste JSON as Classes after that add the Fix the C# name convention and you should be good to go

    public class Item
    {
        [JsonProperty("name")]
        public string Name { get; set; }
        [JsonProperty("level")]
        public int Level { get; set; }
        [JsonProperty("imgUrl")]
        public string ImgUrl { get; set; }
        [JsonProperty("description")]
        public string Description { get; set; }
        [JsonProperty("statistics")]
        public Statistic[] Statistics { get; set; }
    }
    
    public class Statistic
    {
        public Vitality Vitality { get; set; }
    }
    
    public class Vitality
    {
        [JsonProperty("min")]
        public int Min { get; set; }
        [JsonProperty("max")]
        public int Max { get; set; }
    }

With the tool Json2Csharp, your model should be as below:

public class Vitality
{
    [JsonProperty("min")]
    public int Min { get; set; }

    [JsonProperty("max")]
    public int Max { get; set; }
}

public class Statistic
{
    [JsonProperty("Vitality")]
    public Vitality Vitality { get; set; }
}

public class Root
{
    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("level")]
    public int Level { get; set; }

    [JsonProperty("imgUrl")]
    public string ImgUrl { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }

    [JsonProperty("statistics")]
    public List<Statistic> Statistics { get; set; }
}
