Safest way to pass data between forms in c# winforms

Question

I\'m trying to remember a lesson I was taught briefly in school about safely passing data between winforms.

My instructor called it pipelining, though I\'m not

Answer 1

I usually declare my variable in program.cs in your situation, and reach it from anywhere as Program.xxx. but you need a non public way of reaching a variable...

Ahhaaa, another way is as following. when you create a form from another form. Write an overloaded contructor for second form, and pass parameters to that contructor. like:

Form2 frm = new Form2(myParameter);
