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.

sql连接字符串应如下所示，

如果sql server具有Windows身份验证模式

sql connection string should be like below,

if sql server have Windows authentication Mode

"data source=ServerName; Initial Catalog=DatabaseName; Integrated security=true;"

如果sql server具有SQL身份验证模式

if sql server have SQL authentication Mode

"data source=ServerName; Initial Catalog=DatabaseName; Uid=SQLServerLoginId;pwd=SQLServerPassword;" 

祝您编码愉快！

Happy Coding!

检查您的连接字符串.可能是您传递的凭据无法连接到数据库服务器.

谢谢

Check your connection string. May be credentials you are passing are not able to connect to you database server.
