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");
}
}
}

'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

system.diagnostics.process.start("barcodetoword.docx")
end sub
end class

2. 添加二维码到word
c#
using spire.doc;
using spire.barcode;
using system.drawing;
using system.io;
using spire.doc.documents;
using system;
namespace addqrcode
{
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类创建二维码并保存为图片
barcodesettings settings = new barcodesettings();
settings.type = barcodetype.qrcode;
settings.imagewidth = 50;
settings.imageheight = 50;
settings.data = "123456";
settings.data2d = "123456";
settings.x =0.7f;
settings.leftmargin = 1;
settings.showtextonbottom = true;
settings.qrcodeecl = qrcodeecl.q;
settings.qrcodedatamode = qrcodedatamode.numeric;
barcodegenerator generator = new barcodegenerator(settings);
image image = generator.generateimage();
//image.save("qrcode.png", system.drawing.imaging.imageformat.png);//如果需要保存生成的二维码图片，可执行此步骤代码
//添加二维码到正文段落
paragraph paragraph = section.addparagraph();
paragraph.appendpicture(image);
paragraph.format.horizontalalignment = horizontalalignment.right;
//添加二维码图片到word页眉
headerfooter header = section.headersfooters.header;
//headerfooter footer = section.headersfooters.footer;//获取页脚
paragraph headerpara = header.addparagraph();
headerpara.appendpicture(image);
headerpara.format.horizontalalignment = horizontalalignment.center;
//保存文档
