Open Form2 from Form1, close Form1 from Form2

Question

Now, I have two forms, called form1 and form2, in the form1 there\'s a button, when I click it, then open the form2

Question: in the form2, I want to create a button

Answer 1

I did this once for my project, to close one application and open another application.

    System.Threading.Thread newThread;
    Form1 frmNewForm = new Form1;

   newThread = new System.Threading.Thread(new System.Threading.ThreadStart(frmNewFormThread));
this.Close();
        newThread.SetApartmentState(System.Threading.ApartmentState.STA);
        newThread.Start();

And add the following Method. Your newThread.Start will call this method.

    public void frmNewFormThread)()
    {

        Application.Run(frmNewForm);

    }
