Question

As Andrew Hare suggested in his answer:

Create a field to store all the
ListBox instances and then change the
constructor to accept an arbitrary
number of them.

I tried the following

class scaner
{
    readonly IEnumerable<ListBox> listBoxes;

    public IEnumerable<ListBox> ListBoxes
    {
        get { return this.listBoxes; }
    }

    public scaner(params ListBox[] listBoxes)
    {
        this.listBoxes = listBoxes;    
    }
}

This will allow you to do this:

scaner Comp = new scaner(listBox1, listBox2);

---

How can i access listbox1?

In class scaner i’m trying to call this.listBoxes.
(I need to call the listbox1 in scaner class.How can i do/call it?

Thanks for answers.

Answer 1

Why don’t you store the array of listboxes as… an array?

public scanner
{
   private ListBox[] listboxes;

   public scanner(params ListBox[] listboxes)
   {
       this.listboxes = listboxes;
   }
}

Now you can access listbox1 in the call new scanner(listbox1, listbox2) as listboxes[0] in your scanner class.
