生成代码的逻辑是这样，
-1取出要生成代码的表集合，循环逐个生成代码
-2代码生成成功工保存到磁盘上指定目录。
-3窗口上反馈显示生成进度情况。

5.1EM实体模型代码示例

using System;
using System.ComponentModel;

namespace EM
{
    public class SysUserEM
    {
        [Description("用户ID"), Category("系统-用户表"), DisplayName("用户ID")]
        public string UserId { get; set; }

        [Description("名称"), Category("系统-用户表"), DisplayName("名称")]
        public string UserName { get; set; }

        [Description("密码"), Category("系统-用户表"), DisplayName("密码")]
        public string SPwd { get; set; }

        [Description("手机号"), Category("系统-用户表"), DisplayName("手机号")]
        public string SMobile { get; set; }

        [Description("Email"), Category("系统-用户表"), DisplayName("Email")]
        public string SEmail { get; set; }

        [Description("状态"), Category("系统-用户表"), DisplayName("状态")]
        public string UserStatus { get; set; }

        [Description("创建日期"), Category("系统-用户表"), DisplayName("创建日期")]
        public DateTime DTime { get; set; }

        [Description("备注"), Category("系统-用户表"), DisplayName("备注")]
        public string SNote { get; set; }

    }
}

关于字段属性的分组还是需要根据业务需要修改Category()、固定显示顺序可以在DisplayName()加序列字符，比如1，2，3，A，B,C等等。

5.2BLL业务逻辑层代码示例

using System.Data;

#region 用到的别名，复制代码时修改这里即可
using EM = EM.SysUserEM;
using DAL = DAL.SysUserDAL;
#endregion

namespace BLL
{
    public class SysUserBLL
    {
        /// 

        /// 全部查询
        /// 
        /// 
        public static DataTable Select()
        {
            return DAL.Select(DAL.SQL_Select);
        }

        /// 

        /// 模糊查询
        /// 
        /// 
        /// 
        public static DataTable Query(string find)
        {
            return DAL.Query(find);
        }

        /// 

        /// 保存
        /// 
        /// 
        /// 
        public static int Save(EM em, bool insert_or_update)
        {
            if (insert_or_update)
            {
                return DAL.Update(em);
            }
            else
            {
                return DAL.Insert(em);
            }
        }

        /// 

        /// 删除
        /// 
        /// 
        /// 
        public static int Delete(string pk)
        {
            return DAL.Delete(pk);
        }
    }
}
