如何使用C#以低分辨率形式提供高分辨率图像

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;

public static byte[] ResizeImage(byte[] imageData, int width, int height)
{
    using (MemoryStream ms = new MemoryStream(imageData))
    {
        using (Bitmap originalImage = new Bitmap(ms))
        {
            using (Bitmap newImage = new Bitmap(width, height))
            {
                using (Graphics graphics = Graphics.FromImage(newImage))
                {
                    graphics.DrawImage(originalImage, 0, 0, width, height);
                    using (MemoryStream resizedImageStream = new MemoryStream())
                    {
                        newImage.Save(resizedImageStream, ImageFormat.Jpeg);
                        return resizedImageStream.ToArray();
                    }
                }
            }
        }
    }
}
