14.{

16. {
17. public Form1()
18. {
19. InitializeComponent();
20. }
21.
22. private void Form1_Load(object sender, EventArgs e)

32.
33. private void Form1_SizeChanged(object sender, EventArgs e)
34. {
35. if (this.WindowState == FormWindowState.Minimized)//最小化
36. {
37. this.ShowInTaskbar = false;
38. this.notifyIcon1.Visible = true;
39. }
40.
41. }
42.
