刚刚学System.Graphics绘图方法，小小卖弄一下。画一幅对联。
 
      //实例化位图类和绘图类
        System.Drawing.Bitmap bmp=new Bitmap(300,150);
         System.Drawing.Graphics ghs = System.Drawing.Graphics.FromImage(bmp);//情况背景色
        ghs.Clear(Color.Cyan);
        Font font = new Font("仿宋", 12);
         Pen white = new Pen(Color.White);
         Pen red = new Pen(Color.Red);定义画刷
         Brush back=white.Brush;        Brush rdBrush = red.Brush;
       
         StringFormat fomat=new StringFormat();
         fomat.FormatFlags = StringFormatFlags.DirectionVertical;  
         ghs.FillRectangle(back, 20, 30, 30, 120);
         ghs.FillRectangle(back,100 ,0, 100, 25);
         ghs.FillRectangle(back, 250, 30, 30, 120);   //对联内容
         ghs.DrawString("时光易逝", font, rdBrush, 100, 0);
         ghs.DrawString("少壮不努力", font, rdBrush, 20, 30, fomat);
         ghs.DrawString("老大徒伤悲", font, rdBrush, 250, 30, fomat);        System.IO.MemoryStream ms = new System.IO.MemoryStream();
         bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
         Response.ClearContent();
         Response.ContentType = "image/Gif";
         Response.BinaryWrite(ms.ToArray()); 运行结果在我的相册里。
