Nope - no code needs to be written. Just use the connection wizard (just like when connecting to SQL Server, etc.) and connection string will be generated by wizard itself. It will look pretty similar to any other connection strings, like one generate when you connect to SQL server etc. Only difference that instead of OLEDB or ODBC it will say "CUSTOM CONNECT" and will have some different parameters, if you need to make changes to default options of how data is pulled from SAP - packet size etc.
