Create same control of one already declared

Question

I have found in an old topic this:

object newobject = Activator.CreateInstance(comboBox1.GetType);

but doesn't work:

The best overloaded method match for System.Activator.CreateInstance(System.Type, params object[]) has some invalid arguments

The group box is declared, not dynamically, I want to if I click the button Add one Field a new group box equal to the first one (Fields 1) appear.

At the form load event, I can create an instance of array of group box to make easier the access to data on text box?

I hope that someone can help me.

it should be better to create a usercontrol with that design(groupbox with those controls inside),and then add a new instance of it... — terrybozzio, Feb 09 '14 at 15:33

object newobjcet = Activator.CreateInstance(comboBox1.GetType());

You are missing the braces.

@user3289840 Cast it to `Control`. – nvoigt Feb 12 '14 at 09:30
