C#实现打印功能

jopen 9年前

实际开发过程中经常会遇到打印某种报表的情况,用C#实现打印报表的功能。第一,如果报表的大小合适,或者纸张的大小足够放得下报表,则可以选择直接截屏,打印截屏所得的图片;第二,如果报表和纸张的大小不匹配,则可能需要在程序中根据一定格式拼出合适大小的报表。

截屏实现打印报表

private void button3_Click(object sender, EventArgs e)          {                // 截屏                            Form form = this;              if (form != null)              {                  Graphics mygraphics = form.CreateGraphics();                  memoryImage = new Bitmap(form.Width, form.Height, mygraphics);                  Graphics memoryGraphics = Graphics.FromImage(memoryImage);                  memoryGraphics.CopyFromScreen(form.Location.X, form.Location.Y, 0, 0, form.Size);              }                            // 设置打印文档名(如果使用Adobe PDF或者Microsoft Office Document Image Writer打印,则作为默认输出文件名)              this.printDocument1.DocumentName = this.label27.Text;                this.printDocument1.Print();          }                    // printDocument1的PrintPage事件          private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)          {              e.Graphics.Clear(Color.White);              e.Graphics.DrawImage(memoryImage, 0, 0);          }            //定义一个图片          private Bitmap memoryImage = null;
其中button3即为打印按钮,打印按钮的监听事件配置请自行完成(可直接在VS的button3的“属性”页中设置)。printDocument1为PrintDocument空间,请自行添加;其PrintPage事件的监听配置请自行完成。

拼凑特定格式的报表打印

private void button3_Click(object sender, EventArgs e)          {              this.printDocument1.DocumentName = this.label27.Text;                this.printDocument1.Print();          }            private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)          {              e.Graphics.Clear(Color.White);              // 开始绘制文档              // 默认为横排文字              e.Graphics.DrawString("标题",                                       new Font(new FontFamily("宋体"), 22, FontStyle.Bold),                                       System.Drawing.Brushes.Black,                                       170, 10);              e.Graphics.DrawString("性别:" + this.comboBox1.Text,                                      new Font(new FontFamily("宋体"), 14, FontStyle.Bold),                                      System.Drawing.Brushes.Black,                                      20, 50);              e.Graphics.DrawString("联系电话:" + this.textBox9.Text,                                      new Font(new FontFamily("宋体"), 14, FontStyle.Bold),                                      System.Drawing.Brushes.Black,                                      350, 50);              e.Graphics.DrawString("地址:" + this.textBox11.Text,                                      new Font(new FontFamily("宋体"), 14, FontStyle.Bold),                                      System.Drawing.Brushes.Black,                                      20, 80);              // 横线              e.Graphics.DrawLine(Pens.Black, 20, 110, 800, 110);              // 竖排文字              e.Graphics.DrawString("内容",                                      new Font(new FontFamily("宋体"), 14, FontStyle.Bold),                                      System.Drawing.Brushes.Black,                                      20, 120,                                       new StringFormat(StringFormatFlags.DirectionVertical));          }
