将Json反序列化为Entity Framework无法将int转换为type

Question

我一直在尝试反序列化包含表示颜色的int列表的Json字符串，然后使用Entity Framework将其插入到sql数据库中。我对Entity Framework很新，并且读到它不支持原始类型的集合，我想绕过它我可以添加类

public class Colors
{
    public int Id { get; set; }
    public int Color { get; set; }        
}

然后在CharacterColor类中创建一个列表来保存整数

public List<Colors> Colors { get; set; }

但是我在尝试反序列化Json时遇到错误。

Newtonsoft.Json.JsonSerializationException：'将值255转换为'ORAC.Data.Entities.Colors'类型时出错。路径'characterColors [0] .colors [0]'，第1行，第1200位。 ArgumentException：无法从System.Int64转换或转换为ORAC.Data.Entities.Colors。

任何对Entity Framework有更多经验的人都能看到我出错的地方。

Character character = JsonConvert.DeserializeObject<Character>(jsonString);

Json字符串

实体

public class Character
{
    public int UserId { get; set; }
    public int CharacterId { get; set; }
    public string CharacterName { get; set; }

    public string PackedRecipeType { get; set; }
    public string Name { get; set; }
    public string Race { get; set; }
    public List<Dna> Dna { get; set; }
    public List<CharacterColor> CharacterColors { get; set; }
    public List<WardrobeSet> WardrobeSet { get; set; }        
    public string RaceAnimatorController { get; set; }

    public User User { get; set; }
}

public class Dna
{
    public int Id { get; set; }
    public string DnaType { get; set; }
    public int DnaTypeHash { get; set; }
    public string PackedDna { get; set; }
}

public class CharacterColor
{
    public int Id { get; set; }
    public string Name { get; set; }
    public List<Colors> Colors { get; set; }
}

public class WardrobeSet
{
    public int Id { get; set; }
    public string Slot { get; set; }
    public string Recipe { get; set; }
}

public class Colors
{
    public int Id { get; set; }
    public int Color { get; set; }        
}

解决方案我更新了Json并用一个新的对象数组替换了colors数组

 JObject jsonToParse = JObject.Parse(jsonString);            
        JArray characterColors = (JArray)jsonToParse["characterColors"];

        foreach(var item in characterColors)
        {
            JArray colors = (JArray)item["colors"];
            JArray newColorsArray = new JArray();
            var i = 0;
            foreach (var col in colors)
            {
                var color = new Color
                {
                    ColorId = i,
                    Value = (int)col
                };
                newColorsArray.Add(JToken.FromObject(color));
                i++;
            }
            colors.Replace(newColorsArray);
        }
