Option 1 is the option that John suggest.
Option 2 is very bad software design please do not use it.
Option 3 is a really good option
Option 4 is a good option more advanced though.

Answer 2

To pass data to the other form you need to create an instance of it in the class that will invoke it. You then create a constructor that takes the array in the form that you want to pass the data to and have that constructor update a property in the new form. if you are updating a control in the new form you will want to ensure that its a thread safe operation. You can google "Updating control in windows forms thread safe (or wpf)". hope this helps!
