使用Visual Studio宏来自动生成代码 [ Visual Studio | 宏 | 自动生成代码 ]

前言 宏的定义：是组合到一起形成一个命令以自动完成某项任务的一系列命令和指令。(MSDN) 在使用Visual Studio宏实现JS折叠功能的时候就想过用它来实现代码自动生成，有了前面的基础，实现起来就不那么困难了，本文将实现根据表名自动生成相关字段属性的Model代码。 正文 一、预备 1.1 关于宏的新建以及简单用法，请参见这里。 1.2 环境 Microsoft Visual Studio 2008、Microsoft SQL Server 2000 二、目的 根据类名(类名和表名须一致)自动生成列名、字段说明、属性(Properties)、构造函数。 三、实现步骤 3.1 准备测试用表结构 if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[User]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[User]
GO
CREATE TABLE [dbo].[User] (
[UniqueID] [int] IDENTITY (1, 1) NOT NULL ,
[Username] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL ,
[Password] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL ,
[Name] [char] (10) COLLATE Chinese_PRC_CI_AS NULL ,
[UserPermission_Id] [int] NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[User] ADD
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED
(
[UniqueID]
) ON [PRIMARY]
GO
exec sp_addextendedproperty N'MS_Description', N'姓名', N'user', N'dbo', N'table', N'User', N'column', N'Name'
GO
exec sp_addextendedproperty N'MS_Description', N'密码', N'user', N'dbo', N'table', N'User', N'column', N'Password'
GO
exec sp_addextendedproperty N'MS_Description', N'用户名', N'user', N'dbo', N'table', N'User', N'column', N'Username'
GO
exec sp_addextendedproperty N'MS_Description', N'用户权限', N'user', N'dbo', N'table', N'User', N'column', N'UserPermission_Id'
