Can I still use datasource=.\SQLEXPRESS or do I need to change it to : machine_name\SQLEXPRESS for a local instance of SQL Server 2008 Express in C#?
My connection string worked fine in SQL Express 2005, but with the same settings no longer works for 2008.
回答1:
Assuming the instance name is indeed SQLEXPRESS, using .\SQLEXPRESS will work locally.
Use the SQL Server Configuration Manager to find out the correct instance name.

What is the final purpose of the app as it more conventional to include pc name.
