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：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 |
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); |
运行，搞定，这样你的程序就不用拖着一个ICON文件当累赘了。
