Question

型号：

public class User {
    public Guid UserId { get; set; }
    public string UserName { get; set; }
    public virtual Membership Membership { get; set; }
}

public class Membership {
    public Guid UserId { get; set; }
    public DateTime CreateDate { get; set; }
}

的DbContext：

public class UsersContext : DbContext {
    public UsersContext() : base("ApplicationServices") { }
    public DbSet<User> Users { get; set; }
    public DbSet<Membership> Memberships { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder) {
        modelBuilder.Entity<User>().ToTable("aspnet_Users");
        modelBuilder.Entity<Membership>().ToTable("aspnet_Membership");

        //insert relation here to join the two tables
    }
}

这是我用流畅的api玩的第一天，我只是想知道如何能够加入这两张桌子。我如何定义关系？

此外，有关流畅API的任何教程都对您有帮助吗？

Answer 1

您可以使用下一个代码示例：

    modelBuilder.Entity<User>()
                .HasRequired(u=>u.Membership)
                .WithOptional()
                .HasForeignKey(u=>u.UserId)
