我无法在实体属性上使用 [NotMapped] 属性，因为迁移添加命令在下面抛出错误；
这是我的POCO；
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
namespace Domain.Entities
{
public partial class Employer
{
public int EmployerId { get; set; }
public bool? Blacklisted { get; set; }
[NotMapped]
public int TestProperty { get; set; }
}
}
这是我收到的异常消息。

这些是我的包依赖项；
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",
"EntityFramework.Core": "7.0.0-rc1-final",
"EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final",
"EntityFramework.MicrosoftSqlServer.Design": "7.0.0-rc1-final",
"EntityFramework.Relational": "7.0.0-rc1-final",
"EntityFramework.Relational.Design": "7.0.0-rc1-final"
},
知道为什么我无法在我的实体属性中的任何地方使用 [NotMapped] 属性吗？
更新:正如 Don 所建议的，使用 Fluent-api 而不是注释是可行的，但我仍然想使用注释。我的目标是将 [NotMapped] 属性添加到基础实体，这样我就不必将它添加到子实体。
这就是我想要完成的；
将基本 Id 属性映射到实体的主键，而不将 Id 列添加到数据库。
public class EntityBase
{
[NotMapped]
public virtual int Id{ get; set; }
}
//Auto generated POCO
public partial class MyEntity
{
//The primary key
public virtual int MyEntityId{ get; set; }
}
//Partial class that I modify the auto generated Poco
public partial class MyEntity : EntityBase
{
public override int Id
{
get { return MyEntityId; }
set { MyEntityId = value; }
}
}
最佳答案
尝试使用Fluent-API
modelBuilder.Entity<Employer>().Ignore(e => e.TestProperty);
关于c# - EF7 在实体属性中使用 NotMapped 属性时添加迁移错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33928957/
