Is there any reference between the two forms? Is one of them the parent or owner of the other? Are their references stored somewhere?
In case none of this conditions are met You can use Application.OpenForms to find a reference to form1.

Then, if listbox is private (or protected) You should make it public (or internal) or add into form1 some method or property to forward access to it, or to its properties.

Hi
Can you try this.

C#
 Form1.cs

  Form2 f2 = new Form2();
  f2.ShowDialog();

 public  void UpdateListBox(string lstValue)
 {
   listBox1.Items.Add(lstValue);
 }

 Form2.cs
  
  Form1 f1= (Form1)Application.OpenForms["Form1"];
  f1.UpdateListBox(textBox1.Text);
