c# - Entity Framework : Extending partial class with interface without touching the EF-generated classes

Question

我的问题类似于这篇文章: Interface inheritance in Entity Framework

因此，我复制该示例并针对我的问题对其进行修改:

public interface IBaseEntity
{
    DateTime CreatedOn { get; set; }
    string CreatedBy { get; set; }
}

// The following two classes are generated by Entity Framework
public partial class SomeEntity
{
    public int SomeEntityId { get; }
    public string Name { get; set; }
    public DateTime CreatedOn { get; set; }
    public string CreatedBy { get; set; }
}

public partial class OtherEntity
{
    public int OtherEntityId { get; }
    public float Amount { get; set; }
    public DateTime CreatedOn { get; set; }
    public string CreatedBy { get; set; }
}

我想做的是:

public partial class SomeEntity : IBaseEntity
    {
        // No code needed here because the other partial class
        // already has the needed properties
    }

但随后出现以下错误:

Error 64 '[...].SomeEntity' does not implement interface member '[...]IBaseEntity.CreatedOn'
Error 64 '[...].SomeEntity' does not implement interface member '[...]IBaseEntity.CreatedBy'

显然我也能看到这一点。
但是我想编译之后分部类会合二为一，这样编译器就不会报错了。

有什么想法吗？

提前致谢!

我有同样的错误，我解决了将部分类移到 App_Code 文件夹之外的问题!我应该承认我不明白原因:-(
