1.最小化
WindowState = FormWindowState.Minimized;
//最小化时隐藏窗体
this.Visible=false;
2.最大化
WindowState == FormWindowState.Maximized;
3.还原为正常
WindowState == FormWindowState.Normal;
4.在托盘显示
打开 VS.net的工具箱，然后选择NotifyIcon,拖到Form上,在属性中Icon中设置图象添加一个ContextMenu,输入需要的选择项在 NotifyIcon中的ContextMenu属性中可以设置刚添加的ContextMenu 点托盘上的图标 就可以显示选择项
实例部分代码:
#region 还原窗体
private void normalForm()
{
//this.AutoScaleBaseSize = new System.Drawing.Size(5, 15);
//this.ClientSize = new System.Drawing.Size(504, 267);
this.Visible = true;
//this.WindowState=FormWindowState.Normal;
}
#endregion
#region 最小化窗体并在托盘显示,隐藏窗体
private void minForm()
{
WindowState = FormWindowState.Minimized;
this.Visible = false;
this.notifyIconCMPC.Visible = true;
this.myTimer.Enabled = false;
//this.Hide();
//设置气球状工具提示显示的时间为10秒
this.notifyIconCMPC.ShowBalloonTip(30);
}
#endregion
#region 重写WndProc屏蔽掉关闭按钮
