C# / VB.NET 在Word中添加條碼、二維碼

本文介紹如何通過C# 和VB.NET代碼實現在Word文檔中添加條碼和二維碼。代碼中將分為在Word正文段落中、頁眉頁腳中等情況來添加。

使用工具：Free Spire.Office for .NET （免費版）

工具簡介：這是Spire所有.NET平臺下免費產品的集合包，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。

本文添加條碼、二維碼需要在VS程序中添加引用Spire.Doc.dll和Spire.Barcode.dll這兩個dll文件。

dll添加引用效果：

注意：

1. 需要 下載安裝到本地指定路徑，dll文件可在安裝路徑下的Bin文件夾下獲取。

2. 生成的條碼、二維碼會有水印字樣的文字，可通過 此方法去除。

代碼示例

1. 添加條碼到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)
        {
            //調用方法 ApplyKey(string key) 移除水印文字
            Spire.Barcode.BarcodeSettings.ApplyKey("在這里輸入去除水印字樣的序列號");
 
            //創建Document對象，加載Word文檔
            Document doc = new Document();
            doc.LoadFromFile("test.docx");
 
            //獲取第2節
            Section section = doc.Sections[1];
 
            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator類創建條碼并保存為圖片
            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圖片，可執行此步驟代碼
 
            //添加條碼到正文段落
            Paragraph paragraph = section.AddParagraph();
            paragraph.Text = "收貨碼：";
            paragraph.AppendPicture(Image);
            paragraph.Format.HorizontalAlignment = HorizontalAlignment.Right;
 
            //添加條碼圖片到Word頁腳
            HeaderFooter footer = section.HeadersFooters.Footer;
            Paragraph footerpara = footer.AddParagraph();
            footerpara.Text = "掃碼識真偽：";
            footerpara.AppendPicture(Image);
            footerpara.Format.HorizontalAlignment = HorizontalAlignment.Left;
 
            //保存文檔
            doc.SaveToFile("BarCodeToWord.docx", FileFormat.Docx2013);
            System.Diagnostics.Process.Start("BarCodeToWord.docx");
        }
    }
}

條碼添加效果：

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())
                            '調用方法 ApplyKey(string key) 移除水印文字
                            Spire.Barcode.BarcodeSettings.ApplyKey("在這里輸入去除水印字樣的序列號")
 
                            '創建Document對象，加載Word文檔
                            Dim doc As New Document()
                            doc.LoadFromFile("test.docx")
 
                            '獲取第2節
                            Dim section As Section = doc.Sections(1)
 
                            '使用Spire.Barcode的BarcodeSettings和BarcodeGenerator類創建條碼并保存為圖片
                            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圖片，可執行此步驟代碼
 
                            '添加條碼到正文段落
                            Dim paragraph As Paragraph = section.AddParagraph()
                            paragraph.Text = "收貨碼："
                            paragraph.AppendPicture(Image)
                            paragraph.Format.HorizontalAlignment = HorizontalAlignment.Right
 
                            '添加條碼圖片到Word頁腳
                            Dim footer As HeaderFooter = section.HeadersFooters.Footer
                            Dim footerpara As Paragraph = footer.AddParagraph()
                            footerpara.Text = "掃碼識真偽："
                            footerpara.AppendPicture(Image)
                            footerpara.Format.HorizontalAlignment = HorizontalAlignment.Left
 
                            '保存文檔
                            doc.SaveToFile("BarCodeToWord.docx", FileFormat.Docx2013)
                            System.Diagnostics.Process.Start("BarCodeToWord.docx")
                   End Sub
         End Class
End Namespace

2. 添加二維碼到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)
        {
            //調用方法 ApplyKey(string key) 移除水印文字
            Spire.Barcode.BarcodeSettings.ApplyKey("在這里輸入去除水印字樣的序列號");
 
            //創建Document對象，加載Word文檔
            Document doc = new Document();
            doc.LoadFromFile("test.docx");
 
            //獲取第2節
            Section section = doc.Sections[1];
 
            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator類創建二維碼并保存為圖片
            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維碼圖片，可執行此步驟代碼
 
            //添加二維碼到正文段落
            Paragraph paragraph = section.AddParagraph();          
            paragraph.AppendPicture(image);
            paragraph.Format.HorizontalAlignment = HorizontalAlignment.Right;
 
            //添加二維碼圖片到Word頁眉
            HeaderFooter header = section.HeadersFooters.Header;
            //HeaderFooter footer = section.HeadersFooters.Footer;//獲取頁腳
            Paragraph headerpara = header.AddParagraph();
            headerpara.AppendPicture(image);
            headerpara.Format.HorizontalAlignment = HorizontalAlignment.Center;
            
 
            //保存文檔
            doc.SaveToFile("QRCodeToHeader.docx", FileFormat.Docx2013);
            System.Diagnostics.Process.Start("QRCodeToHeader.docx");
        }
    }
}
