It seems that your connection string is not correct, can you check your host name and port number are correct.

Check you have SQL server installed, and you can access it.
If you do, and you can, then put a try...catch block around the connection code, and examine the exception and inner exception. Check names.
Report findings by editing your original question, and add a comment to this answer, so I am alerted you have more info.
