DepTable表  主要作用 存放单位名称

如图：

 

模板下载地址 CodeSmith版本为v6.5

第一步：用CodeSmith模板生成DepTable表相关的存储过程

生成的存储过程如下：

模板生成的DepTable表相关的基础存储过程

 

DepTable_Insert  插入数据
DepTable_Update  更新数据

DepTable_SelectPage  获取分页数据

DepTable_SelectAll   获取所有数据

DepTable_SelectOne  获取某个数据

DepTable_GetCount 获取数量

DepTable_Delete 删除某个数据

}

模板生成的数据层代码

 

主要方法如下：

GetPage  获取分页数据
GetAll  获取所有数据
GetCount 获取总数
GetOne 获取某个数据
Delete  删除
Update 更新

第三步：生成网络通讯程序中使用的实体类（使用protobuf.net进行序列化)

 

模板生成的实体类如下：

// Author:                    msdc
// Created:                    2015-2-8
// Last Modified:            2015-2-8
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using mojoportal.Data;
    
namespace mojoportal.Business
{
     [ProtoContract]
    public class DepTable
    {

#region Constructors

        public DepTable()
        {}
         

#endregion

#region Private Properties

        private int id = -1;
        private string department = string.Empty;
        
#endregion

#region Public Properties

        [ProtoMember(1)]
        public int Id 
        {
            get { return id; }
            set { id = value; }
        }
        [ProtoMember(2)]
        public string Department 
        {
            get { return department; }
            set { department = value; }
        }

#endregion

 


    }
    
}

模板生成的实体类 用protobuf.net序列化

第四步：用模板生成操作类

 

 生成的操作类代码如下：

            return PopulateFromReader(reader);
            }
            
        }
