推荐答案

检查你的代码，仔细查看你的连接字符串。

理想情况下，这将是一些配置文件因此很容易在不重新编译的情况下进行更改，但通常是因为当您从开发环境转移到生产环境时忘记更改它 - 两者通常具有非常不同的连接字符串。



如果以前从未连接过，请尝试在VS中使用服务器资源管理器窗格设置连接：

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DataSource和数据库，指定安全信息，然后按测试连接按钮。

4）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，并查看属性窗格。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。

Check your code, and look closely at your connection string.
Ideally, this will be in a config file of some form so it is easy to change without recompiling, but normally it's because you forgot to change it when you moved from a development environment to production - the two normally have very different connection strings.

If you have never connected before, 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.
