我理解的复杂类型就是简化了编码的操作，实际上在数据库中还是按照约定生成相应的类似“类名_类名”的表结构

public class CompanyAddress    {        public int ID { get; set; }        public string CompanyName { get; set; }        public string StreetAddress { get; set; }        public string City { get; set; }        public string State { get; set; }        public string ZipCode { get; set; }    }    public class FamilyAddress    {        public int ID { get; set; }        public string StreetAddress { get; set; }        public string City { get; set; }        public string State { get; set; }        public string ZipCode { get; set; }    }
