动软.net代码生成器自定义模板（根据自己需要来生成数据访问类）及牛腩的动软的简单使用（原创）
最近用动软生成器三层基于企业库param的方式来生成相应的DAL数据层和MODEL实体类，每次要用到aspnetpage控件的分页，需要重载getlist方法来排序和新写方法获取记录数，网上一直没找到相应的教程，也不知从何下手，摸索了一上午，看到许多人用Codesmith 学了一下 要自己编写模板 感觉没有动软方便，于是摸索原来东软开源后自己来写模板也是那么的方便：
1: 动软.Net代码生成器 （.Net 2.0版）动软2.5
2:官方下载http://www.maticsoft.com/download.aspx 里面的 动软.Net代码生成插件源码
3:解压Builder 里面我是用的vs2008 打开项目根据自己的需要选择相应的项目 我选择的是BuilderDALELParam也就是企业库的param的方式 其他的方式可以看东软的帮助文件
4:打开BuilderDAL.cs，展开 数据层(整个类) 下面就是DAL中的数据库增删改查的一些方法
5:如果要重载Getlist的方法现在就简单了 把自己想新写入的代码写在后面这句的""里 strclass.AppendSpaceLine(2, "“）；自己定义的方法具体写到什么地方 其实没有关系 只要是return strclass.Value;前面一句就可以了 随便哪个方法里面都可以。
2代表缩进 如果遇到里面有字符串如 strclass.AppendSpaceLine(3, "db.AddInParameter(dbCommand,\" tblName\", DbType.AnsiString,\"" + TableName + "\");");用\"" + TableName + "\来包含.表名用"+ TableName +" 来表示。
6:点重新生成后进入lib目录 找到相应的dll文件覆盖到动软安装目录，然后重启动软生成器，下面就是牛腩的东软生成器生成DAL层代码和MODEL层代码的方法了。
（1）：新建服务器
（2）：选择数据库文件
（3）：右键数据库选择 代码 批量生成
(4): 根据自己需要选择表 命令空间 是否去掉前缀以及dal基于什么方式来生成 保存到自己的输出目录就可以了
(5):复制dal和model下的文件到自己的项目中 就可以了。
(6):东软2.5中时间字段如果遇到private DateTime? _createdate= Convert.ToDateTime(getdate);
请改成private DateTime? _createdate;
