visual studio 2012 - Select the connection manager to be used in SSIS source by means of a parameter -

I created 3 different connection managers in one SSIS package, say a conb and conak. How can I select the connection to use in a ado.net source using a parameter? Thank you in the first version of Carlo

The way I would go about it, A simple wrapping in a script IF work with other logic

Return to your source via the SQLDataAdapter and store it in an object variable.

This variable is available as a table to read from any of your part. Assuming that you correctly specify the scope of the variable.
