应用程序不会最小化通知栏

我仍然不能得到这个工作，没有出现在通知栏。这是到目前为止要最小化的完整代码:

private void button6_Click(object sender, EventArgs e)
{
    this.WindowState = FormWindowState.Minimized;
}
private void Form_Resize(object sender, EventArgs e)
{
    if (WindowState == FormWindowState.Minimized)
    {
        this.Hide();
    }
}
private void notifyIcon_Click(object sender, EventArgs e)
{
    this.Show();
    this.WindowState = FormWindowState.Normal;
}

为什么不工作?

应用程序不会最小化通知栏

永远不要在通知区域显示任何内容。跟踪你的代码，看看发生了什么。我添加了一些注释:

private void button6_Click(object sender, EventArgs e)
{
    // When button 6 is clicked, minimize the form.
    this.WindowState = FormWindowState.Minimized;
}
private void Form_Resize(object sender, EventArgs e)
{
    // Catch the case where the form is minimized, including but not limited to
    // clicks on button 6.
    if (WindowState == FormWindowState.Minimized)
    {
        // In that case, hide the form.
        this.Hide();
    }
}
private void notifyIcon_Click(object sender, EventArgs e)
{
    // If the notification icon is clicked, reshow the form as a normal window.
    this.Show();
    this.WindowState = FormWindowState.Normal;
}

现在注意到问题了吗?当窗体最小化时，您所要做的就是隐藏它。你从来没有告诉NotifyIcon显示它的图标!"Visible"属性的默认值为"false"。你必须将其设置为true以使图标显示，并将其设置为false以使其消失。

所以修改代码如下:

private void Form_Resize(object sender, EventArgs e)
{
    // Catch the case where the form is minimized, including but not limited to
    // clicks on button 6.
    if (WindowState == FormWindowState.Minimized)
    {
        // In that case, hide the form.
        this.Hide();
        // And display the notification icon.
        notifyIcon.Visible = true;
        // TODO: You might also want to set other properties on the
        // notification icon, like Text and/or Icon.
    }
}
private void notifyIcon_Click(object sender, EventArgs e)
{
    // If the notification icon is clicked, reshow the form as a normal window.
    this.Show();
    this.WindowState = FormWindowState.Normal;
    // And hide the icon in the notification area.
    notifyIcon.Visible = false;
}

试试下面的代码:

private NotifyIcon notifyIcon;
public Form1()
{
    InitializeComponent();
    button6.Click += (sender, e) =>
        {
            this.WindowState = FormWindowState.Minimized;
        };
    this.Resize += (sender, e) =>
        {
            if (WindowState == FormWindowState.Minimized)
            {
                this.Hide();
                notifyIcon.Visible = true;
                notifyIcon.ShowBalloonTip(1000);
            }
        };
    notifyIcon = new NotifyIcon()
        {
            Text = "I'm here!",
            BalloonTipText = "I'm here!",
            Icon = Icon.ExtractAssociatedIcon(Application.ExecutablePath)
        };
    notifyIcon.Click += (sender, e) =>
        {
            this.Show();
            this.WindowState = FormWindowState.Normal;
            notifyIcon.Visible = false;
        };
}
