C# bitmap转换bitmapsource

方法1：

  System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(image);                
                IntPtr hBitmap = bmp.GetHbitmap();
                System.Windows.Media.ImageSource WpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
                box.Source = WpfBitmap;

方法2：

        [System.Runtime.InteropServices.DllImport("gdi32")]
        static extern int DeleteObject(IntPtr o);
        //Bitmap转BitmapSource
        public BitmapSource BitmapToBitmapSource(System.Drawing.Bitmap bitMap)
        {
            //System.Drawing.Bitmap newBitMap = CaptureBitmapFormBitMap(bitMap, new System.Drawing.Rectangle(0, 0, bitMap.Width, bitMap.Height));
            IntPtr ip = bitMap.GetHbitmap();
            BitmapSource bitmapSource = null;
            bitmapSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                ip, IntPtr.Zero, Int32Rect.Empty,
                 System.Windows.Media.Imaging.BitmapSizeOptions.FromWidthAndHeight(bitMap.Width, bitMap.Height));
            DeleteObject(ip);
            return bitmapSource;
        }

方法1是网上的，方法2是个人总结的，亲测都可以使用。
