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"); } } }

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 doc.SaveToFile("QRCodeToHeader.docx", FileFormat.Docx2013); System.Diagnostics.Process.Start("QRCodeToHeader.docx"); } } }
