[WPF] Obtenir l’icone d’une application

Voici un petit code qui permet d’obtenir l’icone d’une application et d’en faire un ImageSource exploitable via WPF. Rien de bien compliqué pour obtenir l’icone vu que l’on utilise System.Drawing, c’est surtout au niveau de l’Interop qu’il faut regarder ;)

Imports System

Namespace WpfLib

    Public Class mlImage

        Public Shared Function ExtractAssociatedIcon(ByVal path As String) As System.Windows.Media.ImageSource
        
            Dim icon As System.Drawing.Icon = System.Drawing.Icon.ExtractAssociatedIcon(path)

            Return System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon( _
                icon.Handle, _
                System.Windows.Int32Rect.Empty, _
                System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions())
        End Function

    End Class

End Namespace

C#

using System;

namespace WpfLib
{
    public static class mlImage
    {
        public static System.Windows.Media.ImageSource ExtractAssociatedIcon(String path)
        {
            System.Drawing.Icon icon = System.Drawing.Icon.ExtractAssociatedIcon(path);

            return System.Windows.Interop.Imaging.CreateBitmapSourceFromHIcon(
                icon.Handle,
                System.Windows.Int32Rect.Empty,
                System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());
        }
    }
