自动映射器具有未映射属性的问题

Question

好的，首先，我要做的是从 angular 的注册表单中获取用户详细信息，并将这些详细信息注册到 SQL Server 数据库中。我一直在关注几个教程，我想知道为什么当我运行命令进行新迁移时，它会创建一个具有许多不同属性的表，我没有指定。

例如，默认情况下，它会创建以下属性：

migrationBuilder.CreateTable(
name: "User",
columns: table => new
{
Id = table.Column<string>(nullable: false),
UserName = table.Column<string>(maxLength: 256, nullable: true),
NormalizedUserName = table.Column<string>(maxLength: 256, nullable: true),
Email = table.Column<string>(maxLength: 256, nullable: true),
NormalizedEmail = table.Column<string>(maxLength: 256, nullable: true),
EmailConfirmed = table.Column<bool>(nullable: false),
PasswordHash = table.Column<string>(nullable: true),
SecurityStamp = table.Column<string>(nullable: true),
ConcurrencyStamp = table.Column<string>(nullable: true),
PhoneNumber = table.Column<string>(nullable: true),
PhoneNumberConfirmed = table.Column<bool>(nullable: false),
TwoFactorEnabled = table.Column<bool>(nullable: false),
LockoutEnd = table.Column<DateTimeOffset>(nullable: true),
LockoutEnabled = table.Column<bool>(nullable: false),
AccessFailedCount = table.Column<int>(nullable: false)
},

我不知道这些属性来自哪里，我想知道我是否可以改变这一点。我已经按照教程制作了一个网站，但现在我正在尝试自己尝试一个新项目。所以，问题是在使用AutoMapper时，我收到此错误消息，我想知道如何解决此问题：

自动映射程序为您创建了此类型映射，但无法使用当前配置映射您的类型。 帐户模型 -> 应用程序用户(目标成员列表) UserWebAPI.Models.AccountModel -> UserWebAPI.Models.ApplicationUser (Destination membership list)

未映射的属性： 编号 规范化用户名 规范化电子邮件 电子邮件已确认 密码哈希 防伪印章 并发标记 电话号码 电话号码已确认 双因素启用 锁定结束 锁定已启用 AccessFailedCount

我想知道为什么当我运行命令进行新迁移时，它会创建一个具有许多不同属性的表，我没有指定。

由于您ApplicationUser继承了IdentityUser，因此当您进行迁移时，默认情况下它将使用这些属性创建表。您可以按 F12 在 vs(请参阅它继承的IdentityUser<string>)中检查IdentityUser模型。

另请参阅 ASP.NET 核心 中的标识模型自定义

MappingProfile.cs：

public class MappingProfile : Profile
{
public MappingProfile()
{
CreateMap<AccountModel, ApplicationUser>();
}
}
