SQL数据库里图片无法读取,该怎么处理

SQL数据库里图片无法读取
我之前把除了图片以外的个人信息全部输进去数据库了，后来又单独输图片（更新上次的记录），图片也已二进制保存进了数据库，可是读取的时侯出现了问题，但是不知道问题出在哪里？以下代码省去了存储其他数据，主要是看看第二部分读取图片
点击picture存储图片
private void pictureBox9_Click(object sender, EventArgs e)
  {
  openFileDialog1.Filter = "*jpg|*.JPG|*.GIF|*.GIF|*.BMP|*.BMP";
  if (openFileDialog1.ShowDialog() == DialogResult.OK)
  {
  string fullpath = openFileDialog1.FileName;//文件路径
  FileStream fs = new FileStream(fullpath, FileMode.Open);
  byte[] imagebytes = new byte[fs.Length];//把图片读成字节形式，赋给一个字节数组（image类型是以二进制数字存储）
  BinaryReader br = new BinaryReader(fs);
  imagebytes = br.ReadBytes(Convert.ToInt32(fs.Length));
  //打开数据库
  SqlConnection cn = new SqlConnection(@"server=.\SQLEXPRESS;AttachDbFilename=C:\USERS\DY\DOCUMENTS\VISUAL STUDIO 2008\PROJECTS\PROPERTY MANAGEMENT SYSTEM\PROPERTY MANAGEMENT SYSTEM\PMS.MDF;Integrated Security=True;Connect Timeout=30;User Instance=True");
  cn.Open();
  SqlCommand cm = new SqlCommand("update [personal info] set ownerPic=@ownerPic where ownerID='"+textBox1.Text+"'", cn);
  cm.Parameters.Add("ownerPic", SqlDbType.Image);
  cm.Parameters["ownerPic"].Value = imagebytes;
  cm.ExecuteNonQuery();
  cn.Close();
   
  }  
  }

读取显示在picture上面

private void button9_Click(object sender, EventArgs e)
  {
  byte[] imagebytes = null;
  //打开数据库
  SqlConnection con = new SqlConnection(@"server=.\SQLEXPRESS;AttachDbFilename=C:\USERS\DY\DOCUMENTS\VISUAL STUDIO 2008\PROJECTS\PROPERTY MANAGEMENT SYSTEM\PROPERTY MANAGEMENT SYSTEM\PMS.MDF;Integrated Security=True;Connect Timeout=30;User Instance=True");
  con.Open();
  SqlCommand com = new SqlCommand("select ownerPic from [personal info] where ownerID='" + textBox1.Text + "'", con);
  SqlDataReader dr = com.ExecuteReader();
  while (dr.Read())
  {
  imagebytes = (byte[])dr.GetValue(1);
  }
  dr.Close();
  com.Clone();
  con.Close();
  MemoryStream ms = new MemoryStream(imagebytes);
  Bitmap bmpt = new Bitmap(ms);
  pictureBox9.Image = bmpt;
  }


------解决方案--------------------
Asp.net是用
Respone.writeBytes

要转成Bitmap 的话还真心没接触过

帮顶吧~~
