Why is image not showing up when the code is running?

<Canvas HorizontalAlignment="Left" Height="198" Margin="10,59,0,0" VerticalAlignment="Top" Width="144" Background="#FFF9F4F4">
            <Image Name="ImgCard" Height="178" Width="112" Canvas.Top="6" Canvas.Left="16"/>
        </Canvas>

BitmapImage myBitmapImage = new BitmapImage();
                myBitmapImage.BeginInit();
                myBitmapImage.UriSource = new Uri(@"C://image//cards//*.png");
                ImageSource imageSource = myBitmapImage;
                ImgCard.Source = imageSource;
