How to set window icon in code behind in wpf?

Something like

myWindow.Icon = new BitmapImage(new Uri("/VBDAdvertisement;component/Images/logoVBD.png"));

You may need to qualify the path more though.

Edit: As i thought the path should be in pack-uri format:

"pack://application:,,,/VBDAdvertisement;component/Images/logoVBD.png"

wpf icons code-behind

This is the correct way to do it (assuming MyIcon.ico is placed on the root folder of a WPF project named MyApplication):

Uri iconUri = new Uri("pack://application:,,,/MyApplication;component/MyIcon.ico");myWindow.Icon = BitmapFrame.Create(iconUri);

This is also what actually happens when you set the Icon property for the window in XAML.

When just setting the Icon to a new Bitmap, it will not be rendered smoothly and correctly, but instead quite a bit pixelated.

wpf icons code-behind

Try this its absolutely working for both png as well as ico image format.

window.Icon = BitmapFrame.Create(Application.GetResourceStream(new Uri("LiveJewel.png", UriKind.RelativeOrAbsolute)).Stream);
