How can I reduce size of a jpeg file before storing it into sql server database?

public byte[] ResizeImageFile(byte[] imageFile, int targetSize) // Set targetSize to 1024
        {
            using (System.Drawing.Image oldImage = System.Drawing.Image.FromStream(new MemoryStream(imageFile)))
            {
                Size newSize = new Size(50, 100);
                using (Bitmap newImage = new Bitmap(newSize.Width, newSize.Height, PixelFormat.Format24bppRgb))
                {
                    using (Graphics canvas = Graphics.FromImage(newImage))
                    {
                        canvas.SmoothingMode = SmoothingMode.AntiAlias;
                        canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
                        canvas.PixelOffsetMode = PixelOffsetMode.HighQuality;
                        canvas.DrawImage(oldImage, new Rectangle(new Point(0, 0), newSize));
                        MemoryStream m = new MemoryStream();
                        newImage.Save(m, ImageFormat.Jpeg);
                        return m.GetBuffer();
                    }
                }
            }
        }

I get an error at memorystream constructor saying invalid parameters.
