有没有办法直接用DbModelBuilder用EF6创建表？

public class MyDbContext : DbContext
{
    public MyDbContext() : base("name=MyConnectionString")
    {
    }

    public DbSet<MyEntity> MyEntities { get; set; }

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

        modelBuilder.Entity<MyEntity>()
            .ToTable("MyTable")
            .HasKey(e => e.Id);

        // 添加其他映射规则和约束
    }
}

public class MyEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
    // 其他属性
}

using (var context = new MyDbContext())
{
    // 添加数据
    var entity = new MyEntity { Name = "Example" };
    context.MyEntities.Add(entity);
    context.SaveChanges();

    // 查询数据
    var entities = context.MyEntities.ToList();

    // 修改数据
    entity.Name = "Updated Example";
    context.SaveChanges();

    // 删除数据
    context.MyEntities.Remove(entity);
    context.SaveChanges();
}
