本文介绍了一种方法将WPF中的BitmapSource转换为System.Drawing.Bitmap，涉及了从WPF BitmapSource获取HBITMAP，创建BitmapSource并复制像素数据到System.Drawing.Bitmap的过程。适用于需要在.NET应用中使用WPF图像资源的情况。

private BitmapSource bs(Bitmap bt)
        {
            IntPtr ip = bt.GetHbitmap();
            BitmapSource bitmapSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                ip, IntPtr.Zero, Int32Rect.Empty,
                System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());
            DeleteObject(ip);
            return bitmapSource;
        }



public System.Drawing.Bitmap WpfBitmapSourceToBitmap(BitmapSource s)

{

System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(s.PixelWidth, s.PixelHeight, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);

System.Drawing.Imaging.BitmapData data = bmp.LockBits(new System.Drawing.Rectangle(System.Drawing.Point.Empty, bmp.Size),

System.Drawing.Imaging.ImageLockMode.WriteOnly, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);

s.CopyPixels(Int32Rect.Empty, data.Scan0, data.Height * data.Stride, data.Stride);

bmp.UnlockBits(data);

return bmp;

}
