Visual Studio服务器资源管理器添加数据连接(从App_Data附加mdf文件) [英] Visual Studio Server Explorer Add Data Connection (Attach mdf file from App_Data)

问题描述

大家好
我正在用AP.NET开发购物车. 2天前，我在"SQL SERVER 2008 R2"中创建了一个数据库.它创建成功，一切正常.然后，我将名为"ESTORE"的数据库复制到我项目的App_Data中.但是，现在我想在服务器资源管理器=>数据连接=>添加数据连接"中添加它.每次它给我一个错误，例如尝试为文件C:\ Users \ cYpH3R x3r0 \ My Documents \ Visual Studio 2010 \ Websites \ New \ App_Data \ ESTORE.mdf附加一个自动命名的数据库失败.存在具有相同名称的数据库，或者无法打开指定的文件，或者该数据库位于UNC共享上.

这里给出了链接，它最能描述我的问题.

抱歉，如果这个问题听起来很丑，我是ASP.NET和SQL Server的新手(最近从PHP切换)

Hello guys
I am developing a shopping cart in AP.NET. 2 days ago i created a database in "SQL SERVER 2008 R2". It was created successfully and everything went fine. I then copied that Database named "ESTORE" to the App_Data of my Project. But now i want to add this in "Server Explorer => Data Connections => Add Data Connection". and everytime it gives me an error like an attempt to attach an auto-named database for file C:\Users\cYpH3R x3r0\My Documents\Visual Studio 2010\Websites\New\App_Data\ESTORE.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

Link is given here, that describes my problem best.

Sorry if that questions sounds ugly, i am new to ASP.NET and SQL Server (Recently Switched from PHP)

推荐答案

使用的数据连接，因为Coz App_Data文件夹具有更高的级别安全，并且更难以访问

used data connection instead, coz App_Data folder has higher security and is more difficult to access
