C# 建数sqlserver据库程序 用winform运行SQL脚本创建数据库
需要用到2个引用：
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
路径大概是:C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies
只要安装了SQL2008就行，具体百度。

如果实在找不着,又没积分下载的话,用ADO.NET分段吧...
这是直接把sql脚本的语句挂到数据库中运行，ADO.NET有很多限制，又因为数据库导出的脚本又基本中枪，所以只能乳此了。
首先,界面长这样:
弄成这样不难...随便搞搞就行...就不放代码了。
时间是为了提示用户程序没挂掉，别乱点。。。
构建数据库语句,目标字符串:
这是手动拼接的
CREATE DATABASE 数据库名
ON
(
NAME = '数据库名_data',
FILENAME = 'D:\SQL\数据库名_data.mdf',
SIZE = 5MB,
MAXSIZE=5,
FILEGROWTH = 20
)
LOG ON
(
NAME = '数据库名_log',
FILENAME = 'D:\SQL\数据库名_log.ldf',
SIZE = 2MB,
MAXSIZE=20,
FILEGROWTH = 1MB
);
注意事项:
眼号啊,逗号啊,括号啊全都不能省
直接上代码：
注释已经说的很明白了，就不罗嗦了，按照代码调整好界面控件的name属性就能用了，

可以加上进度条，我做的进度条是个水货，没监听线程进行情况，就自个在那跑，
99%卡住后等待运行完关掉，就不贴出来了。。。
