Ensure the form is disposed

[osmarjunior]

How to ensure that a form is disposed?
When I work with modal forms I do the following:

using (Form1 frm = new Form1())
{
frm.ShowDialog();
}

As far as I read, when it ends the using scope, the form is disposed.
But if I don't use modal forms, like this:

Form1 frm = new Form1();
frm.Show();

In this case, when the user clicks on the X button, or a close button,
the form is disposed?

Junior,

Yes, when the user clicks on the close button, the form is disposed of.
When the message to close is received for the form, it calls Dispose.

Hope this helps.
