Hidden form not closing

Question

I have a C# Form, where you have Form1 shown at the start, and when you press Go you are taken to Form2. Form1

Answer 1

Try this:

Hide();
Form2 form2 = new Form2();
form2.Closed += (s, args) => this.Close();
form2.Show();

This will close Form1 when you close Form2. If the user presses X or ALT+F4 or RightClick -> Close on Form2 The Form2 and the hidden Form1 will close.
