将二进制数据转换为图片并打印到页面上

  using System.Drawing;
  using System.IO;
  int w = 100;//设定宽度
  int h = 100;//设定高度
  System.IO.FileStream fs = System.IO.File.Open("图片路径", System.IO.FileMode.Open);
  byte[] b = new byte[fs.Length];
  fs.Read(b, 0, (int)fs.Length);
  MemoryStream ms = new MemoryStream(b);
  Image i = new Bitmap(ms, true);
  Image ii = new Bitmap(i, new Size(w, h));
  ii.Save(Response.OutputStream, Imaging.ImageFormat.Jpeg);
  fs.Close();
