C#托盘图标

增加一个notifyIcon1和contextMenuStrip1，并设置notifyIcon1的ContextMenuStrip属性为contextMenuStrip1。然后添加如下事件：

 

// 托盘图标支持

// 重载窗体的Resize事件，当窗体最小化时隐藏

private voidForm1_Resize(object sender, EventArgs e)

{

    if (this.WindowState ==FormWindowState.Minimized)

    {

        this.Hide();

    }

}

 

//给contextMenuStrip1增加退出

private voidtoolStripMenuExit_Click(object sender,EventArgs e)

{

    Close();

}

 

// 双击拖盘图标，隐显主窗体

private voidnotifyIcon1_DoubleClick(object sender,EventArgs e)

{

    if (this.Visible)

        this.Hide();

    else

    {

        // 一定要先Show，再设窗体状态

        this.Show();

        if (this.WindowState ==FormWindowState.Minimized)

            this.WindowState= FormWindowState.Normal;

    }

}
