推荐答案

检查你的连接字符串：它是否与你的SQL服务器实例和用户访问权限匹配？

一种方法检查是尝试在服务器资源管理器窗格中设置VS中的连接：

1）打开服务器资源管理器。

2）右键单击数据连接并选择添加连接

3）在随后的对话框中，选择您的数据源和数据库，指定安全信息，然后按测试连接按钮。

4）连接工作，按确定

5）在服务器资源管理器窗格中突出显示数据库，然后查看属性窗格。将显示连接字符串的工作示例，您可以将其复制并粘贴到应用程序或配置文件中。或者在您的情况下，与您朋友给您使用的应用程序进行比较。

Check your connection string: does it match your SQL server instance and user access?
One way to check is to try setting up a connection in VS with the Server Explorer pane:
1) Open Server Explorer.
2) Right click "Data connections" and select "Add connection"
3) In the dialog that follows, select your DataSource, and database, specify the security info, and press the "Test connection" button.
4) When the connection works, press "OK"
5) Highlight your database in the Server Explorer pane, and look at the Properties pane. A working example of the connection string will be shown, which you can copy and paste into your app or config file. Or in your case, compare against the one the application your friend gave you is using.
