C# 将Json反序列化为实体框架无法将int转换为type
我一直在尝试反序列化一个Json字符串，该字符串包含一个表示颜色的int列表，然后使用Entity Framework将其插入sql数据库。我对Entity Framework非常陌生，读到它不支持基元类型的集合，我想绕过它，我可以添加这个类C# 将Json反序列化为实体框架无法将int转换为type,c#,json,entity-framework,C#,Json,Entity Framework,我一直在尝试反序列化一个Json字符串，该字符串包含一个表示颜色的int列表，然后使用Entity Framework将其插入sql数据库。我对Entity Framework非常陌生，读到它不支持基元类型的集合，我想绕过它，我可以添加这个类 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

在Json中，颜色定义为int数组，而不是新颜色类的对象数组。应该更像颜色：[{Id:0，颜色：255}，{Id:2，颜色：255}，…] 因此JSON是不正确的，在JSON中，颜色数组基本上是作为列表发送的
颜色：[255255,0,0,0,0255255,0,0,0,0255255,0,0,0,0255255,0,0,0,0]colors:[{Id:0，Color:255}，{Id:1，Color:255}，…]您应该执行1或2，因为您的数据似乎不太复杂，无法完成3的工作。在Json中，您将颜色定义为int数组，而不是新颜色类的对象数组。应该更像颜色：[{Id:0，颜色：255}，{Id:2，颜色：255}，…] 因此JSON是不正确的，在JSON中，颜色数组基本上是作为列表发送的
