C# 建數sqlserver據庫程序 用winform運行SQL腳本創建數據庫

需要用到2個引用：

using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;

路徑大概是:C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies

只要安裝了SQL2008就行，具體百度。

如果實在找不着,又沒積分下載的話,用ADO.NET分段吧...

這是直接把sql腳本的語句掛到數據庫中運行，ADO.NET有很多限制，又因爲數據庫導出的腳本又基本中槍，所以只能乳此了。

首先,界面長這樣:

弄成這樣不難...隨便搞搞就行...就不放代碼了。

時間是爲了提示用戶程序沒掛掉，別亂點。。。

構建數據庫語句,目標字符串:

這是手動拼接的

CREATE DATABASE 數據庫名
ON
(
    NAME = '數據庫名_data',
    FILENAME = 'D:\SQL\數據庫名_data.mdf',
    SIZE = 5MB,
    MAXSIZE=5,
    FILEGROWTH = 20
)
LOG ON
(
    NAME = '數據庫名_log',
    FILENAME = 'D:\SQL\數據庫名_log.ldf',
    SIZE = 2MB,
    MAXSIZE=20,
    FILEGROWTH = 1MB
);
 

注意事項:
眼號啊,逗號啊,括號啊全都不能省

直接上代碼：

註釋已經說的很明白了，就不羅嗦了，按照代碼調整好界面控件的name屬性就能用了，
