Wpf enables the icon to be displayed on the system tray, and wpf icons on the system tray

During the previous wpf operation, I wanted to display the program running icon in the taskbar. The result showed that the system tray of wpf is different from that of winform. The previous method did not work.

Many of the information searched on the internet is winform, and there are few wpf documents.

Finally, I will sort out and share my work to help others and myself.

Some errors are inevitable in the article. please correct me. The following code

 

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 {// tray policyicon; // register the AreaIcon attribute for the tray icon public static readonly DependencyP Roperty AreaIconProperty = DependencyProperty. register ("AreaIcon", typeof (ImageSource), typeof (GWindow); // Register the AreaText attribute, public static readonly DependencyProperty AreaTextProperty = DependencyProperty. register ("AreaText", typeof (string), typeof (GWindow); // registers the AreaVisibility attribute to display the hidden Tray Icon public static readonly DependencyProperty AreaVisibilityProperty = DependencyProperty. register ("AreaVisibility", typeof (bool), typeof (GWindow); // register the AreaMenuItems attribute, which is used to right-click the tray and choose 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); policyicon = new policyicon (); policyicon. tex T = AreaText; if (! DesignerProperties. GetIsInDesignMode (this) {policyicon. Icon = GetImageSource (AreaIcon);} policyicon. Visible = AreaVisibility; if (this. AreaMenuItems! = Null & this. areaMenuItems. count> 0) {policyicon. 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); policyicon. visible = false; policyicon. 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 );}}}

 

The code used for front-end calling directly replaces Window with GWindow, And you can set properties later.

In AreaMenuItems, right-click the tray icon and choose settings

<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>
