C#最小化到托盘+双击托盘恢复

1.添加notifyIcon控件，并添加Icon，否则托盘没有图标（托盘右键菜单也可直接在属性里添加）；

 

2.响应Form的Resize或SizeChanged消息：


  2. // Hide to system tray
  3. private void Form1_Resize(object sender, EventArgs e)
  4. {
  5. if (this.WindowState == FormWindowState.Minimized)
  6. {
  7. this.Hide();
  8. this.ShowInTaskbar = false;
  9. this.notifyIcon.Visible = true;
  10. }
  11. }

 

3.双击托盘图标恢复需要响应notifyIcon的DoubleClick消息：


  2. // Show from system tray
  3. private void notifyIcon_DoubleClick(object sender, EventArgs e)
  4. {
  5. if (this.WindowState == FormWindowState.Minimized)
  6. {
  7. this.Show();
  8. this.WindowState = FormWindowState.Normal;
  9. notifyIcon.Visible = false;
  10. this.ShowInTaskbar = true;
  11. }
  12. }
