Clear controls does not dispose them – what is the risk?

by

Asking for modifications like this is pointless, the Windows Forms team has been disbanded quite a while ago. It is in maintenance mode, only security issues and OS incompatibilities are considered.

It is otherwise simple enough to create your own method to do this:

  public static class ExtensionMethods {
    public static void Clear(this Control.ControlCollection controls, bool dispose) {
      for (int ix = controls.Count - 1; ix >= 0; --ix) {
        if (dispose) controls[ix].Dispose();
        else controls.RemoveAt(ix);
      }
    }
  }

Now you can write:

  panel1.Controls.Clear(true);
