Remove (), Clear () or Dispose ()

Question

Simple question...

I have controls that the user can move around my form at runtime. And they can also remove them. Should I just call .Dispose(); when they click the "Delete" button, or I need to do something like panel1.Controls.Clear(Control); ?... Or something else?

Thanks:)

Answer 1

You must remove it from the Controls parent collection, as described in Darin Dimitrov’s answer, and also call Dispose:

 panel.Controls.Remove(someControlInstance); someControlInstance.Dispose(); 

You should always call Dispose on objects that implement IDisposable when you are done with them, so that any unmanaged resources that they own are freed immediately.

Answer 2

Just remove the control from the panel:

 panel.Controls.Remove(someControlInstance); 

As soon as there are no more links to it, it will be garbage collected and unmanaged resources will be correctly allocated.
