wpf 让图标显示在系统托盘

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

 

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Windows;

using System.Windows.Input;

using System.Windows.Markup;

using System.Windows.Media;

using System.Windows.Threading;

using Drawing = System.Drawing;

using System.Windows.Forms;



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

<loacl:GWindow x:Class="WpfWin.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:loacl="clr-namespace:WpfWin"

        xmlns:forms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

        Title="MainWindow" Height="350" Width="525" AreaText="MainWindow" ShowInTaskbar="False" AreaVisibility="True"  AreaIcon="Image/clock.ico" Icon="Image/clock.ico">

    <loacl:GWindow.AreaMenuItems>

        <forms:MenuItem Text="Open" DefaultItem="True" />

        <forms:MenuItem Text="Exit" />

    </loacl:GWindow.AreaMenuItems>

    <Grid/>

</loacl:GWindow>
