C#/VB.NET 在Word中添加条码、二维码的示例代码

本文介绍如何通过c# 和vb.net代码实现在word文档中添加条码和二维码。代码中将分为在word正文段落中、页眉页脚中等情况来添加。

使用工具：

free spire.office for .net （免费版）

工具简介：

这是spire所有.net平台下免费产品的集合包，包含spire.barcode.dll、spire.dataexport.dll、spire.pdf.dll、spire.doc.dll、spire.docviewer.forms.dll 、spire.pdfviewer.forms.dll 、spire.presentation.dll 、spire.xls.dll等dll可用于操作word/pdf/excel/ppt等文件。

本文添加条码、二维码需要在vs程序中添加引用 spire.doc.dll 和 spire.barcode.dll 这两个dll文件。

dll添加引用效果：

注意：

1. 需要下载安装到本地指定路径，dll文件可在安装路径下的bin文件夹下获取。

2. 生成的条码、二维码会有水印字样的文字，可通过此方法去除。

代码示例

1. 添加条码到word

c#

using spire.doc;
using spire.barcode;
using system.drawing;
using system.io;
using spire.doc.documents;

namespace addbarcode
{
  class program
  {
    static void main(string[] args)
    {
      //调用方法 applykey(string key) 移除水印文字
      spire.barcode.barcodesettings.applykey("在这里输入去除水印字样的序列号");

      //创建document对象，加载word文档
      document doc = new document();
      doc.loadfromfile("test.docx");

      //获取第2节
      section section = doc.sections[1];

      //使用spire.barcode的barcodesettings和barcodegenerator类创建条码并保存为图片
      barcodesettings settings = new barcodesettings();
      settings.type = barcodetype.code128;
      settings.data = "123456789";
      settings.data2d = "123456789";
      settings.showtext = false;
      settings.barheight = 4;
      settings.x = 0.3f;
      settings.hasborder = true;
      settings.borderwidth = 0.5f;
      settings.bordercolor = color.aliceblue;
      settings.backcolor = color.wheat;
      barcodegenerator barcodegenerator = new barcodegenerator(settings);
      image image = barcodegenerator.generateimage();
      //image.save("barcode.png", system.drawing.imaging.imageformat.png);//如果需要保存生成的barcode图片，可执行此步骤代码

      //添加条码到正文段落
      paragraph paragraph = section.addparagraph();
      paragraph.text = "收货码：";
      paragraph.appendpicture(image);
      paragraph.format.horizontalalignment = horizontalalignment.right;

      //添加条码图片到word页脚
      headerfooter footer = section.headersfooters.footer;
      paragraph footerpara = footer.addparagraph();
      footerpara.text = "扫码识真伪：";
      footerpara.appendpicture(image);
      footerpara.format.horizontalalignment = horizontalalignment.left;

      //保存文档
      doc.savetofile("barcodetoword.docx", fileformat.docx2013);
      system.diagnostics.process.start("barcodetoword.docx");
    }
  }
}

vb.net

imports spire.doc
imports spire.barcode
imports system.drawing
imports system.io
imports spire.doc.documents


namespace addbarcode
  class program
    private shared sub main(args as string())
      '调用方法 applykey(string key) 移除水印文字
      spire.barcode.barcodesettings.applykey("在这里输入去除水印字样的序列号")

      '创建document对象，加载word文档
      dim doc as new document()
      doc.loadfromfile("test.docx")

      '获取第2节
      dim section as section = doc.sections(1)

      '使用spire.barcode的barcodesettings和barcodegenerator类创建条码并保存为图片
      dim settings as new barcodesettings()
      settings.type = barcodetype.code128
      settings.data = "123456789"
      settings.data2d = "123456789"
      settings.showtext = false
      settings.barheight = 4
      settings.x = 0.3f
      settings.hasborder = true
      settings.borderwidth = 0.5f
      settings.bordercolor = color.aliceblue
      settings.backcolor = color.wheat
      dim barcodegenerator as new barcodegenerator(settings)
      dim image as image = barcodegenerator.generateimage()
      'image.save("barcode.png", system.drawing.imaging.imageformat.png);//如果需要保存生成的barcode图片，可执行此步骤代码

      '添加条码到正文段落
      dim paragraph as paragraph = section.addparagraph()
      paragraph.text = "收货码："
      paragraph.appendpicture(image)
      paragraph.format.horizontalalignment = horizontalalignment.right

      '添加条码图片到word页脚
      dim footer as headerfooter = section.headersfooters.footer
      dim footerpara as paragraph = footer.addparagraph()
      footerpara.text = "扫码识真伪："
      footerpara.appendpicture(image)
      footerpara.format.horizontalalignment = horizontalalignment.left

      '保存文档
      doc.savetofile("barcodetoword.docx", fileformat.docx2013)
      system.diagnostics.process.start("barcodetoword.docx")
    end sub
  end class
end namespace
