大家好:
想詢問程式一執行，form1跟form2跳出，form2按取消跟叉叉 form1關閉，為什麼要加Application.Exit(); 才能將整個程式關掉，單寫.close(); form1會變縮小視窗
這樣寫法是否正確? 謝謝

program.cs

 static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }

form1.cs

private void Form1_Load(object sender, EventArgs e)
        {
            this.Enabled = false; //form1 disabled
            Form2 form2 = new Form2 ();
            this.WindowState = FormWindowState.Maximized;           
            form2.TopMost = true;
            form2.Show();
            
        }

form2.cs

private void Cancel_Click(object sender, EventArgs e)
        {
            Form1 form1 = new Form1();
            form1.Close();
            this.Close();
            Application.Exit();
        }

        private void Form2_FormClosed(object sender, FormClosedEventArgs e)
        {
            Application.Exit();
        }
