   cn= new OdbcConnection("DSN=mysql1;");
   cn.Open();
   cmd=new OdbcCommand(MyString,cn);
   try

   byte[]tmp;
   Bitmap MyImage;
   tmp=(byte[])rs["si_photo"];
if(File.Exists("tmp.tmp"))  //文件是否存在

   File.Delete("tmp.tmp");
   }
FileStream fs = new FileStream("tmp.tmp",FileMode.CreateNew);
BinaryWriter w = new BinaryWriter(fs);
w.Write(tmp);
w.Close();
  pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage ;
  MyImage = new Bitmap("tmp.tmp");
  pictureBox1.ClientSize = new Size(pictureBox1.Width,pictureBox1.Height);
  pictureBox1.Image=(Image)MyImage ;

   System.Windows.Forms.MessageBox.Show(rs["si_name"].ToString());
}

}
catch
