网上看到的，页面只要一个PictureBox控件 private void CreateImage(PictureBox Picturebox) { float Total = 0.0f, Tmp; //转换成单精度。也可写成Convert.ToInt32 Total = Convert.ToSingle(94.0); //设置字体，fonttitle为主标题的字体 Font fontlegend = new Font("verdana", 9); Font fonttitle = new Font("verdana", 10, FontStyle.Bold); //背景宽 int width = 350; int bufferspace = 15; int legendheight = fontlegend.Height * 10 + bufferspace; //高度 int titleheight = fonttitle.Height + bufferspace; int height = width + legendheight + titleheight + bufferspace;//白色背景高 int pieheight = width; Rectangle pierect = new Rectangle(0, titleheight, width, pieheight); //加上各种随机色 System.Collections.ArrayList colors = new System.Collections.ArrayList(); Random rnd = new Random(); for (int i = 0; i < 2; i++) colors.Add(new SolidBrush(Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255)))); //创建一个bitmap实例 Bitmap objbitmap = new Bitmap(width, height); Graphics objgraphics = Graphics.FromImage(objbitmap); //画一个白色背景 objgraphics.FillRectangle(new SolidBrush(Color.White), 0, 0, width, height); //画一个亮黄色背景 objgraphics.FillRectangle(new SolidBrush(Color.Beige), pierect); //以下为画饼图(有几行row画几个) float currentdegree = 0.0f; //画通过人数 objgraphics.FillPie((SolidBrush)colors[1], pierect, currentdegree,Convert.ToSingle( 82.0) / Total * 360); currentdegree += Convert.ToSingle(82.0) / Total * 360; //未通过人数饼状图 objgraphics.FillPie((SolidBrush)colors[0], pierect, currentdegree,((Convert.ToSingle(94.0)) - (Convert.ToSingle(82.0))) / Total * 360); currentdegree += ((Convert.ToSingle(94.0)) - (Convert.ToSingle(82.0))) / Total * 360; //以下为生成主标题 SolidBrush blackbrush = new SolidBrush(Color.Black); SolidBrush bluebrush = new SolidBrush(Color.Blue); string title = " 机关单位成绩统计饼状图: " + "\n \n\n"; StringFormat stringFormat = new StringFormat(); stringFormat.Alignment = StringAlignment.Center; stringFormat.LineAlignment = StringAlignment.Center; objgraphics.DrawString(title, fonttitle, blackbrush, new Rectangle(0, 0, width, titleheight), stringFormat); //列出各字段与得数目 objgraphics.DrawRectangle(new Pen(Color.Red, 2), 0, height + 10 - legendheight, width, legendheight + 50); objgraphics.DrawString("----------------统计信息------------------",fontlegend, bluebrush, 20, height - legendheight + fontlegend.Height * 1 + 1); objgraphics.DrawString("统计单位: 测试" ,fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 3 + 1); objgraphics.DrawString("统计年份: 2012年",fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 4 + 1); objgraphics.DrawString("统计期数: 第一期",fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 5 + 1); objgraphics.FillRectangle((SolidBrush)colors[1], 5, height - legendheight + fontlegend.Height * 8 + 1, 10, 10); objgraphics.DrawString("报名总人数: " + Convert.ToString(Convert.ToSingle(94.0)), fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 7 + 1); objgraphics.FillRectangle((SolidBrush)colors[0], 5, height - legendheight + fontlegend.Height * 9 + 1, 10, 10); objgraphics.DrawString("通过总人数: " + Convert.ToString(Convert.ToSingle(82.0)), fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 8 + 1); objgraphics.DrawString("未通过人数: " + ((Convert.ToSingle(94.0)) - (Convert.ToSingle(82.0))), fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 9 + 1); objgraphics.DrawString("通过率: " + Convert.ToString((Convert.ToSingle(82.0) / Convert.ToSingle(94.0)) * 100) + " %", fontlegend, blackbrush, 20, height - legendheight + fontlegend.Height * 10 + 1); //Response.ContentType = "image/Jpeg"; //objbitmap.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg); pictureBox1.Width = objbitmap.Width; pictureBox1.Height = objbitmap.Height; objgraphics.Dispose(); //objbitmap.Dispose(); pictureBox1.Width = objbitmap.Width; pictureBox1.BackgroundImage = objbitmap; }
