C# WPF当图像被加载时，宽度和高度被切换

<Image Source="path_to_your_image.jpg" Stretch="None" />

<Image Source="path_to_your_image.jpg" Stretch="UniformToFill" />

<Viewbox>
    <Image Source="path_to_your_image.jpg" />
</Viewbox>

private void Image_Loaded(object sender, RoutedEventArgs e)
{
    Image img = sender as Image;
    if (img != null)
    {
        double containerWidth = img.ActualWidth;
        double containerHeight = img.ActualHeight;
        double imageWidth = img.Source.Width;
        double imageHeight = img.Source.Height;

        // 根据需要调整图像尺寸
        if (containerWidth / containerHeight > imageWidth / imageHeight)
        {
            img.Width = containerHeight * (imageWidth / imageHeight);
            img.Height = containerHeight;
        }
        else
        {
            img.Width = containerWidth;
            img.Height = containerWidth * (imageHeight / imageWidth);
        }
    }
}

<Image Source="path_to_your_image.jpg" Loaded="Image_Loaded" />
