Question

我尝试更改用户表的主键并将其映射到其他名称每当我映射到字符串pk没有问题，但它给出了整数pk下面的错误 - AspNetUsers-＆gt; Id

正如我所见，只有ApplicationUser类无法映射到AspNetUsers表

下面的代码会出错，

无效的对象名称＆＃39; dbo.ApplicationUser1＆＃39;。

好吧，我找到了解决方案。使用此代码更改OnModelCreating()方法中的映射。

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<CustomApplicationUser>().ToTable("AspNetUsers");
        modelBuilder.Entity<CustomRole>().ToTable("AspNetRoles");
        modelBuilder.Entity<CustomUserLogin>().ToTable("AspNetUserLogins");
        modelBuilder.Entity<CustomUserRole>().ToTable("AspNetUserRoles");
        modelBuilder.Entity<CustomUserClaim>().ToTable("AspNetUserClaims");

        modelBuilder.Entity<CustomApplicationUser>().Property(r => r.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<CustomRole>().Property(r => r.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
        modelBuilder.Entity<CustomUserClaim>().Property(r => r.Id).HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
}

希望这有助于某人。如果不是，请告诉我，我可能会有所帮助。：）
