How to view the ConnectionString value of Flat File Connection while debugging?

Question

There seem to be 2 ways to set up the connection string in FlatFile connection properties:

1. Using ConnectionString property
2. Using ConnectionString expression

Which one will be used? Is there any way to see this value during the debug, or to print it out (is adding a new task, 'print in a file', a reasonable workaround)?

Answer 1

As with everything in SSIS, an expression is used to overwrite the value of a property.
