C#打印原理其实就是生成MDI文件,那么什么是MDI文件呢?MDI是虚拟打印的文档,系统碰到MDI的时候会自动以打印的方式处理。所以,不管用什么模板,什么方式;能在PrintPage事件处理中,生成一张要打印内容的图片就OK了!
C#打印原理应用实例:
- #region 打印
- private void btnPrint_Click(object sender, EventArgs e)
- {
- //C#打印原理之打印预览
- //PrintPreviewDialog ppd = new PrintPreviewDialog();
- PrintDocument pd = new PrintDocument();
- //C#打印原理之设置边距
- Margins margin = new Margins(20, 20, 20, 20);
- pd.DefaultPageSettings.Margins = margin;
- ////C#打印原理之纸张设置默认
- //PaperSize pageSize = new PaperSize("First custom size", 800, 600);
- //pd.DefaultPageSettings.PaperSize = pageSize;
- //C#打印原理之打印事件设置
- pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
- //ppd.Document = pd;
- //ppd.ShowDialog();
- try
- {
- pd.Print();
- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message, "打印出错",
- MessageBoxButtons.OK, MessageBoxIcon.Error);
- pd.PrintController.OnEndPrint(pd, new PrintEventArgs());
- }
- }
- //C#打印原理之打印事件处理
- private void pd_PrintPage(object sender, PrintPageEventArgs e)
- {
- string date = lblDate.Text; //当前日期
- string flowId = lblFlowId.Text; //流水号
- string payDate = PayDate.Year.ToString() + "年" +
- PayDate.Month.ToString() + "月"; //应收年月
- string adminId = lblAdminId.Text; //操作员编号
- string baseExpense = lblBaseExpense.Text; //应交基本费用
- string fine = lblFine.Text; //罚款数目
- string upExpense = lblUpExpense.Text; //上月上余
- string actualExpense = txtActualExpense.Text; //实际应交费用
- string chineseExpense = DecimalToChinese.ConvertSum(actualExpense);
- //实际应交费用的中文大写
- //C#打印原理之读取图片模板
- Image temp = Image.FromFile(@"Receipts.jpg");
- GetResultIntoImage(ref temp, UserId, flowId, date, baseExpense,
- fine, upExpense, actualExpense, chineseExpense, payDate, adminId);
- int x = e.MarginBounds.X;
- int y = e.MarginBounds.Y;
- int width = temp.Width;
- int height = temp.Height;
- Rectangle destRect = new Rectangle(x, y, width, height);
- e.Graphics.DrawImage(temp, destRect, 0, 0, temp.Width,
- temp.Height, System.Drawing.GraphicsUnit.Pixel);
- }
- /// <summary>
- /// 将收费结果填充到图片模板
- ///C#打印原理
- /// </summary>
- private void GetResultIntoImage(
- ref Image temp,
- string userId,
- string flowId,
- string currentDate,
- string baseExpense, string actualExpense,
- string chineseExpense,
- string payDate,
- string adminName)
- {
- //C#打印原理之读取图片模板
- Graphics g = Graphics.FromImage(temp);
- Font f = new Font("宋体", 12);
- Brush b = new SolidBrush(Color.Black);
- //C#打印原理之填充数据到图片模板(位置要在制作图片模板的时候度量好)
- g.DrawImage(temp, 0, 0, temp.Width, temp.Height);
- g.DrawString(userId, f, b, 168, 105);
- g.DrawString(UserName, f, b, 166, 134);
- g.DrawString(flowId, f, b, 535, 105);
- g.DrawString(currentDate, f, b, 535, 134);
- g.DrawString(baseExpense, f, b, 219, 202);
- g.DrawString(fine, f, b, 372, 202);
- g.DrawString(upExpense, f, b, 486, 202);
- g.DrawString(actualExpense, f, b, 596, 202);
- g.DrawString(chineseExpense, f, b, 196, 238);
- g.DrawString(payDate, f, b, 176, 269);
- g.DrawString(adminName, f, b, 497, 298);
- g.Dispose();
- }
