wpf 让图标显示在系统托盘_.NET_编程开发_程序员俱乐部

上次做wpf时想把程序运行的图标显示在任务栏，结果发现wpf的系统托盘和winform的不一样，以前的方法不管用了。

网上搜的好多都是winform的资料，wpf的很少。

最后我把我现在做好的整理分享下，方便别人，也方便自己。

文章难免有些错误，欢迎指正，下面代码

class="brush:csharp;gutter:true;">using System;

using System.ComponentModel;
using System.Windows;
using System.Windows.Input;

namespace WpfWin
{
    public class GWindow : Window
    {
        //托盘
        NotifyIcon notifyIcon;

        //注册AreaIcon属性，用于托盘的图标
        public static readonly DependencyProperty AreaIconProperty =
            DependencyProperty.Register("AreaIcon", typeof(ImageSource), typeof(GWindow));
        //注册AreaText属性，用于鼠标滑到托盘图标时显示的文字
        public static readonly DependencyProperty AreaTextProperty =
            DependencyProperty.Register("AreaText", typeof(string), typeof(GWindow));
        //注册AreaVisibility属性，用于显示隐藏托盘图标
        public static readonly DependencyProperty AreaVisibilityProperty =
            DependencyProperty.Register("AreaVisibility", typeof(bool), typeof(GWindow));
        //注册AreaMenuItems属性，用于托盘右键在单的列表
        public static readonly DependencyProperty AreaMenuItemsProperty =
            DependencyProperty.Register("AreaMenuItems", typeof(List<MenuItem>), typeof(GWindow), new PropertyMetadata(new List<MenuItem>()));

        protected override void OnInitialized(EventArgs e)
        {
            base.OnInitialized(e);

            notifyIcon = new NotifyIcon();
            notifyIcon.Text = AreaText;
            if (!DesignerProperties.GetIsInDesignMode(this))
            {
                notifyIcon.Icon = GetImageSource(AreaIcon);
            }
            notifyIcon.Visible = AreaVisibility;

            if (this.AreaMenuItems != null && this.AreaMenuItems.Count > 0)
            {
                notifyIcon.ContextMenu = new ContextMenu(this.AreaMenuItems.ToArray());
            }
        }

        public List<MenuItem> AreaMenuItems
        {
            get { return (List<MenuItem>)GetValue(AreaMenuItemsProperty); }
            set { SetValue(AreaMenuItemsProperty, value); }
        }

        public ImageSource AreaIcon
        {
            get { return (ImageSource)GetValue(AreaIconProperty); }
            set { SetValue(IconProperty, value); }
        }

        public string AreaText
        {
            get { return (string)GetValue(AreaTextProperty); }
            set { SetValue(AreaTextProperty, value); }
        }

        public bool AreaVisibility
        {
            get { return (bool)GetValue(AreaVisibilityProperty); }
            set { SetValue(AreaVisibilityProperty, value); }
        }

        protected override void OnClosing(CancelEventArgs e)
        {
            base.OnClosing(e);
            notifyIcon.Visible = false;
            notifyIcon.Dispose();
            AreaMenuItems.Clear();
        }

        private static Drawing.Icon GetImageSource(ImageSource icon)
        {
            if (icon == null)
            {
                return null;
            }
            Uri iconUri = new Uri(icon.ToString());
            return new Drawing.Icon(System.Windows.Application.GetResourceStream(iconUri).Stream);
        }
    }
}

前台调用时的代码,直接将Window  换成  GWindow，在后面就可以设置属性了

AreaMenuItems   中设置托盘图标右键菜单，自己设定
