关于窗体最小化问题

a12321321321312321 2008-07-10 06:12:00

我想把程序图标最小化到屏幕的右下角,不知道为什么老是报错,请高手指教~~
最小化代码

private void Form1_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.ShowInTaskbar = false;
this.Visible = false;
this.TrayIcon.Visible = true;
}
}

错误提示:
“MyData.Form1”不包含“TrayIcon”的定义,并且找不到可接受类型为“MyData.Form1”的第一个参数的扩展方法“TrayIcon”(是否缺少 using 指令或程序集引用?)

在notificationicon 组建的 click 事件里面把 form.WindowsState 设成 Normal( 好像是nomal吧,或者有什么restore 方法)

这是托盘。在C#里有这个控件。你加到窗体里了吗?

NotifyIcon

你得添加一个notificationico(好像是这个名字,在toolbox里)到窗体
并且命名为TrayIcon
