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
