Question

我有两张桌子：

分类和用户

CategoryId 是一个int， UserId 是一个字符串（nvarchar（128））。我为我的用户提供了这个映射：

this.HasMany(t => t.ForbiddenCategories)
    .WithMany(t => t.ForbiddenUsers)
    .Map(m =>
    {
        m.ToTable("UserForbiddenCategories");
        m.MapLeftKey("CategoryId");
        m.MapRightKey("UserId");
    });

但是当我为此创建一个数据库时，它会这样做：

CREATE TABLE [dbo].[UserForbiddenCategories](
    [UserId] [int] NOT NULL,
    [CategoryId] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_dbo.UserForbiddenCategories] PRIMARY KEY CLUSTERED 
(
    [UserId] ASC,
    [CategoryId] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[UserForbiddenCategories]  WITH CHECK ADD  CONSTRAINT [FK_dbo.UserForbiddenCategories_dbo.Categories_UserId] FOREIGN KEY([UserId])
REFERENCES [dbo].[Categories] ([Id])
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[UserForbiddenCategories] CHECK CONSTRAINT [FK_dbo.UserForbiddenCategories_dbo.Categories_UserId]
GO

ALTER TABLE [dbo].[UserForbiddenCategories]  WITH CHECK ADD  CONSTRAINT [FK_dbo.UserForbiddenCategories_dbo.IdentityUsers_CategoryId] FOREIGN KEY([CategoryId])
REFERENCES [dbo].[IdentityUsers] ([Id])
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[UserForbiddenCategories] CHECK CONSTRAINT [FK_dbo.UserForbiddenCategories_dbo.IdentityUsers_CategoryId]
GO

这完全是错误的方式。 CategoryId应该是带有FK到类别的int，UserId应该是带有FK到IdentityUsers的字符串。

谁能告诉我我做错了什么？或者我如何告诉EF更改地图？

干杯，
