C#实现打印功能

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)); }
