推荐答案

尝试使用服务器资源管理器窗格在VS中设置连接：

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）当连接工作时，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您的应用程序或配置文件中。



如果您无法建立连接方式，那么你需要仔细查看你的数据库的位置，以及你需要提供什么才能访问它。

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.

If you can't establish a connection that way, then you need to look carefully at where your DB is, and what you need to provide in order to access it.
