Are you connecting using windows authentication or SQL authentication? What is the error you get when you try to login?

If you enter your PC name, you have to also add the name of the SQL server instance:

C#

MYPCNAME/SQLEXPRESS

For example.
Otherwise you may get away with (localhost) but that's not a good idea for release code, as it means each PC needs it's own instalation of SQL Server, and that will cause immense problems!

Have a look here: SQL Server 2012 connection strings - ConnectionStrings.com[^] - it gives examples of what your connection string should look like, and explains why.
