C#条码生成及打印实例代码

本文实例为大家分享了C#条码生成及打印的方法，供大家参考，具体内容如下

string BarcodeString = "13043404455";//条码
  int ImgWidth = 520;
  int ImgHeight = 120;

  //打印按钮
  private void button1_Click(object sender, EventArgs e)
  {
   //实例化打印对象
   PrintDocument printDocument1 = new PrintDocument();

   //设置打印用的纸张,可以自定义纸张的大小(单位：mm).  当打印高度不确定时也可以不设置
   //printDocument1.DefaultPageSettings.PaperSize = new PaperSize("Custum", 585, 800);

   //注册PrintPage事件，打印每一页时会触发该事件
   printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);

   //开始打印
   printDocument1.Print();

   //打印预览
   //PrintPreviewDialog ppd = new PrintPreviewDialog();
   //ppd.Document = printDocument1;
   //ppd.ShowDialog();
  }


  //打印事件
  private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
  {
   StringBuilder sb = new StringBuilder();
   sb.Append("\r\n\r\n\r\n");
   sb.Append("*******兴隆超市*******\r\n");
   sb.Append("品名-----数量-----价格\r\n");
   sb.Append("精品白沙 1  8元\r\n");
   sb.Append("张新发槟榔 1  10元\r\n");
   sb.Append("合计：  2  18元\r\n");
   sb.Append("---收银员：张三---\r\n");
   sb.Append("---技术支持：李四---\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n");

   DrawPrint(e, sb.ToString(), BarcodeString, ImgWidth, ImgHeight);

  }

  public void DrawPrint(PrintPageEventArgs e, string PrintStr, string BarcodeStr, int BarcodeWidth, int BarcodeHeight)

    }

   }
   catch (Exception ex)
   {
    MessageBox.Show(ex.ToString());
   }
  }

  public System.Drawing.Image CreateBarcodePicture(string BarcodeString, int ImgWidth, int ImgHeight)
  {
   BarcodeLib.Barcode b = new BarcodeLib.Barcode();//实例化一个条码对象
   BarcodeLib.TYPE type = BarcodeLib.TYPE.CODE128;//编码类型

   //获取条码图片
   System.Drawing.Image BarcodePicture = b.Encode(type, BarcodeString, System.Drawing.Color.Black, System.Drawing.Color.White, ImgWidth, ImgHeight);

  }
