Why forms dosn't dispose?

Hi all,

Take this sample:

Code:

---

public class F : Form
{
private System.Windows.Forms.Button button1;
  F()
  {
      this.button1 = new Button();
      this.button1.Click += new System.EventHandler(this.button1_Click);
  }

  private void button1_Click(object sender, System.EventArgs e)
  {
      F f = new F ();
      f.Show();
  }

  [STAThread]
  static void Main()
  {
      Forms.Application.Run(new F());
  }
 
}

---

Into button1_Click I create a new F() but this form does not get disposed as I aspected (f go out of scope!).

The strange is that if I do this with some other class type (try with a new Class1) this get disposed!

Why they have differents behaviors?

Thanx!

use the .Close() on the form first

No, I'd like to know why forms doesn't dispose automatically as any other class.
What's different?

This is dependent on the garbage collector. Forms might get automatically promoted to the next generation. You can force a full collection by typing gc.Collect to see if the collector clears the form. I also believe that if the form is still visible, it should be on the freachable list and therefore will not be collected. Of course you can force disposal using the IDispose interface. But again, if the form is visible then this may not be permitted.
