wpf 讓圖標顯示在系統托盤


上次做wpf時想把程序運行的圖標顯示在任務欄,結果發現wpf的系統托盤和winform的不一樣,以前的方法不管用了。

網上搜的好多都是winform的資料,wpf的很少。

最后我把我現在做好的整理分享下,方便別人,也方便自己。

文章難免有些錯誤,歡迎指正,下面代碼

 

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
    {
        //托盤
        NotifyIcon notifyIcon;

        //注冊AreaIcon屬性,用於托盤的圖標
        public static readonly DependencyProperty AreaIconProperty =
            DependencyProperty.Register("AreaIcon", typeof(ImageSource), typeof(GWindow));
        //注冊AreaText屬性,用於鼠標滑到托盤圖標時顯示的文字
        public static readonly DependencyProperty AreaTextProperty =
            DependencyProperty.Register("AreaText", typeof(string), typeof(GWindow));
        //注冊AreaVisibility屬性,用於顯示隱藏托盤圖標
        public static readonly DependencyProperty AreaVisibilityProperty =
            DependencyProperty.Register("AreaVisibility", typeof(bool), typeof(GWindow));
        //注冊AreaMenuItems屬性,用於托盤右鍵在單的列表
        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);
        }
    }
}

 

前台調用時的代碼,直接將Window  換成  GWindow,在后面就可以設置屬性了

AreaMenuItems   中設置托盤圖標右鍵菜單,自己設定
<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>
