Answer 1

调用他的代码
  private Image CreateImage()
        {
            Image img2 = null;
            object o = this.Tag;
            Seal.BLL.DynamicImage bllimm = new Seal.BLL.DynamicImage();
            List<Seal.Model.DynamicImage> modelimglist = new List<Seal.Model.DynamicImage>();
            if (o == null)
            {
                return img2;
            }
            modelimglist = bllimm.GetModelForSealID(int.Parse(o.ToString()));
            Seal.BLL.SealInfo bllSealInfo = new Seal.BLL.SealInfo();
            Seal.Model.SealInfo modelSeal = bllSealInfo.GetModel(int.Parse(o.ToString()));
            Bitmap bit = null;
            Image img = CustomControls.ImageFormat.ReturnPhoto(modelSeal.SealImage);
            bit = new Bitmap(img);
            Graphics g = Graphics.FromImage(bit);
            //设置高质量插值法
            g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;
            //设置高质量呈现平滑程度
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
            //清空画布并以透明背景色填充
            g.Clear(System.Drawing.Color.Transparent);
            g.DrawImage(img, new Point(0, 0));            foreach (Seal.Model.DynamicImage item in modelimglist)
            {
                int xpoint = int.Parse(item.SealPoint.Substring(0, item.SealPoint.LastIndexOf(",")));
                int ypoint = int.Parse(item.SealPoint.Substring(item.SealPoint.LastIndexOf(",") + 1));
                if (xpoint < 0)
                {
                    xpoint = 0;
                } if (ypoint < 0)
                {
                    ypoint = 0;
                }
                Rectangle r = new Rectangle(xpoint, ypoint, (int)item.SealWidth, (int)item.SealHeight);
                if (item.SealFontSize != null)
                {
                    Font f = new Font(item.SealFont, (float)item.SealFontSize);
                    if (item.IsUp == false && item.Angle != null)
                    {
                        Point centerPoint = new Point(r.X + r.Width / 2, r.Y + r.Height / 2);
                        PaintOneText(g, f, centerPoint, (float)r.X, (float)r.Y, (float)item.Angle, (float)item.TopMargin, DateTime.Now.ToString("yyyy.MM.dd"), item.IsUp, (float)r.Height, (float)r.Width);
                    }
                    else
                    {                        Random ran = new Random();
                        int temp = ran.Next(10000000, 99999999);
                        StringFormat format = new StringFormat();
                        format.Alignment = StringAlignment.Center;
                        g.DrawString(temp.ToString(), f, Brushes.Black, r, format);
                    }                }
                if (item.LineWidth > 0)
                {
                    int num = (int)item.LineStyle;
                    g.DrawRectangle(new Pen(Brushes.Black, (int)item.LineWidth), r);
                }
            }
            return ImageFormat.toBitmap(bit, 160);
        }

图像是非托管资源,没看到你在任何地方调用dispose方法,是否内存溢出了?
