让WPF应用最小到系统托盘?可以调用System.Windows.Forms.NotifyIcon来实现,下面是示例代码:

public partial class MainWindow : Window
    {
        private NotifyIcon notifyIcon;
        public MainWindow()
        {
            InitializeComponent();
 
            this.notifyIcon = new NotifyIcon();
            this.notifyIcon.BalloonTipText = "系统监控中... ...";
            this.notifyIcon.ShowBalloonTip(2000);
            this.notifyIcon.Text = "系统监控中... ...";
            this.notifyIcon.Icon = new System.Drawing.Icon(@"AppIcon.ico");
            this.notifyIcon.Visible = true;
            //打开菜单项
            System.Windows.Forms.MenuItem open = new System.Windows.Forms.MenuItem("Open");
            open.Click += new EventHandler(Show);
            //退出菜单项
            System.Windows.Forms.MenuItem exit = new System.Windows.Forms.MenuItem("Exit");
            exit.Click += new EventHandler(Close);
            //关联托盘控件
            System.Windows.Forms.MenuItem[] childen = new System.Windows.Forms.MenuItem[] { open, exit };
            notifyIcon.ContextMenu = new System.Windows.Forms.ContextMenu(childen);
 
            this.notifyIcon.MouseDoubleClick += new System.Windows.Forms.MouseEventHandler((o, e) =>
            {
                if (e.Button == MouseButtons.Left) this.Show(o, e);
            });
        }
 
        private void Show(object sender, EventArgs e)
        {
            this.Visibility = System.Windows.Visibility.Visible;
            this.ShowInTaskbar = true;
            this.Activate();
        }
 
        private void Hide(object sender, EventArgs e)
        {
            this.ShowInTaskbar = false;
            this.Visibility = System.Windows.Visibility.Hidden;
        }
 
        private void Close(object sender, EventArgs e)
        {
            System.Windows.Application.Current.Shutdown();
        }
    }

运行时发现,程序一定要能找到ICON,否则会报错,并且ICON还没包含到程序中,需要一个额外的ICON来做托盘图标。当然这个都是能解决的:

1
this.notifyIcon.Icon = new System.Drawing.Icon(@"AppIcon.ico");

将以上一句替换成下面内容,意思就是读取程序图标,来作为托盘图标

1
this.notifyIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(System.Windows.Forms.Application.ExecutablePath);

此代码实测有效,StarGate – Csharp里面的例子:

System.Windows.Forms.NotifyIcon nIcon;  //  托盘
private void ShowIcon()
{//显示托盘
    this.nIcon = new System.Windows.Forms.NotifyIcon();
    this.nIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(System.Windows.Forms.Application.ExecutablePath);
    this.nIcon.Visible = true;
    nIcon.MouseClick += OnShowIcon;
    this.nIcon.ShowBalloonTip(3000, "StarGate - CSharp""测试版本,勿外传",System.Windows.Forms.ToolTipIcon.Info);
}
 
private void OnShowIcon(object sender,EventArgs e)
{//显示窗口并隐藏托盘
    this.Show();
    this.nIcon.Visible = false;
    this.TipText.Content = "等待中...";
}
