使用WPF在C#中异步加载BitmapImage

using System.Windows.Media.Imaging;

namespace AsyncImageLoading
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            LoadImageAsync("https://example.com/image.jpg");
        }

        private async void LoadImageAsync(string imageUrl)
        {
            try
            {
                var bitmapImage = new BitmapImage();
                bitmapImage.BeginInit();
                bitmapImage.UriSource = new Uri(imageUrl);
                bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
                bitmapImage.EndInit();
                await Task.Run(() => bitmapImage.DownloadCompleted += BitmapImage_DownloadCompleted);
            }
            catch (Exception ex)
            {
                MessageBox.Show($"Error: {ex.Message}");
            }
        }

        private void BitmapImage_DownloadCompleted(object sender, EventArgs e)
        {
            var bitmapImage = sender as BitmapImage;
            Image.Source = bitmapImage;
        }
    }
}
