you need to provide valid connection string
go to https://www.connectionstrings.com/sql-server-2008/[^] and check the connection string formats you can use.

note that Database property is for name of the database and it is not equal to database file name.

Quote:
The database name must be specified with the keyword 'database' (or one of its aliases) as in the following: "AttachDbFileName=|DataDirectory|\data\YourDB.mdf;integrated security=true;database=YourDatabase". An error will be generated if a log file exists in the same directory as the data file and the 'database' keyword is used when attaching the primary data file. In this case, remove the log file. Once the database is attached, a new log file will be automatically generated based on the physical path.

Solution 2

Your connection string is using TrustedConnection. This tells the SQL Server to use the account of the user running the code. It's telling you your account doesn't have permissions to the database you're trying to use.
