ASP.NET Mvc Preview 5 演示Demo #3 实现MVC批量上传文件
上一篇： ASP.NET Mvc Preview 5 演示Demo #2 实现Membership角色权限控制这个演示项目实现了在ASP.NET MVC 中批量上传多个文件的功能。【ok】 开发环境：Visual Studio 2008 SP1 ＋ ASP.NET MVC Preview 5 ＋ Linq To Sql ＋ SQL Server 2005 ASP.NET MVC Preview 5 下载地址： http://www.codeplex.com/aspnet/R ... spx?ReleaseId=16775【Step By Step 操作步骤】 1、SQL Server 2005 执行下面的Sql查询脚本。该Sql脚本将生成一个新的mike108mvp数据库。 注意：这个数据库脚本与Demo #2 的脚本完全一样，如果你已经执行过Demo #2的数据库脚本，则可以跳过这一步。【ok】   Code
/**//****** 删除后生成数据库 ******/
USE [master]
GO
IF EXISTS (SELECT name FROM sys.databases WHERE name = N'mike108mvp')
DROP DATABASE [mike108mvp]
CREATE DATABASE [mike108mvp]
GO
/**//****** 生成表结构 ******/
USE [mike108mvp]
GO
/**//****** 对象: Table [dbo].[User] 脚本日期: 09/03/2008 20:59:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
