NPOI是一个强大的开源库，尤其在C#编程环境中，它为处理Microsoft Office文档提供了极大的便利。这个库的版本2.5.6专注于对Excel、Word和PowerPoint等文件的读写操作。以下是对NPOI 2.5.6在C#中使用方法的详细说明。 ### 1. 安装NPOI库你需要通过NuGet包管理器在你的C#项目中安装NPOI库。在Visual Studio中，右键点击你的项目，选择“管理NuGet程序包”，然后在搜索框中输入“NPOI”。找到NPOI 2.5.6并安装。 ### 2. Excel操作 #### 2.1 读取Excel文件使用NPOI可以方便地读取XLS和XLSX格式的Excel文件。以下代码展示了如何打开一个Excel文件并读取第一张工作表的数据： ```csharp using NPOI.SS.UserModel; using NPOI.XSSF.UserModel; // 打开Excel文件 FileStream file = new FileStream("path_to_your_file.xlsx", FileMode.Open, FileAccess.Read); var workbook = new XSSFWorkbook(file); // 获取第一个工作表 ISheet sheet = workbook.GetSheetAt(0); // 遍历行数据 for (int rowIndex = 0; rowIndex < sheet.LastRowNum + 1; rowIndex++) { IRow row = sheet.GetRow(rowIndex); if (row != null) { // 遍历单元格数据 for (int cellIndex = 0; cellIndex < row.LastCellNum; cellIndex++) { ICell cell = row.GetCell(cellIndex); if (cell != null) Console.WriteLine(cell.ToString()); } } } // 关闭文件流 file.Close(); ``` #### 2.2 写入Excel文件创建新的Excel文件或向现有文件添加数据也很简单： ```csharp // 创建新工作簿 workbook = new XSSFWorkbook(); // 添加新工作表 ISheet sheet = workbook.CreateSheet("Sheet1"); // 写入数据 IRow row = sheet.CreateRow(0); ICell cell = row.CreateCell(0); cell.SetCellValue("Hello, World!"); // 写入文件 using (FileStream stream = new FileStream("output.xlsx", FileMode.Create, FileAccess.Write)) { workbook.Write(stream); } ``` ### 3. Word操作 NPOI对于Word文档的处理能力相对较弱，主要支持读取。以下代码展示了如何读取一个DOCX文件的内容： ```csharp using NPOI.XWPF.UserModel; // 打开Word文件 FileStream file = new FileStream("path_to_your_file.docx", FileMode.Open, FileAccess.Read); XWPFDocument document = new XWPFDocument(file); // 读取段落 foreach (XWPFParagraph paragraph in document.Paragraphs) { Console.WriteLine(paragraph.Text); } // 关闭文件流 file.Close(); ``` ### 4. PowerPoint操作 NPOI同样支持读取PPTX文件，但不支持写入。以下代码展示了如何读取幻灯片的文本内容： ```csharp using NPOI.PPTX.UserModel; // 打开PowerPoint文件 FileStream file = new FileStream("path_to_your_file.pptx", FileMode.Open, FileAccess.Read); XSLFSlideShow slideshow = new XSLFSlideShow(file); // 读取每张幻灯片的文本 foreach (XSLFSlide slide in slideshow.Slides) { StringBuilder slideText = new StringBuilder(); foreach (XSLFShape shape in slide.Shapes) { if (shape is XSLFTextShape) { slideText.Append(shape.Text); } } Console.WriteLine($"Slide Text: {slideText}"); } // 关闭文件流 file.Close(); ``` NPOI 2.5.6库提供了灵活且高效的API，使开发者能够在C#中轻松处理Office文档。尽管它在某些功能上可能有限（如Word写入和PowerPoint编辑），但在读取和创建Excel文件方面，NPOI无疑是一个强大而可靠的工具。

================ * Introduction * ================ This project is the .NET port of POI project. With NPOI, you can read/write Excel and Word files easily. It has a wide application. For example, you can use it a to generate a Excel report without Microsoft Office suite installed on your server and more efficient than call Microsoft Excel ActiveX at background; you can also use it to extract text from Office documents to help you implement full-text indexing feature (most of time this feature is used to create search engines). ========================= * Nissl Introduction * ========================= NPOI was used to be maintained by Neuzilla ( Tony's first startup company). After Neuzilla is closed in 2018, Nissl Lab maintains NPOI. Nissl Lab is a NGO org created by Nissl LLC. The trademake NPOI is hold by Nissl in order to avoid abuse. ================== * NPOI Source Code * ================== https://github.com/nissl-lab/npoi/ ================== * LICENSE COMPLIANCE * ================== You are NOT allowed to remove NPOI logo or Nissl/Neuzilla brand (even text). This is a must of Apache license. This shows basic respects to the previous contributors of NPOI. You must state that you are using NPOI no matter you are creating a commercial product or an open source project. ====================== * System Requirement * ====================== VS2015 and above medium trust environment in ASP.NET ================= * Nissl in social network * ================= Linkedin: https://www.linkedin.com/company/nissl Github: https://github.com/nissl-lab ================ * Team Members * ================ Tony Qu - coodinator, developer ------------------------------- From: Shanghai, China Participated since Sep, 2008 Time Zone: GMT+8 -------------------------------------------------------------------------------- NPOI 1.2.1 -------------------------------------------------------------------------------- Huseyin Turfekcilerli - developer -------------------- From: Istanbul, Turkey Participated since Nov, 2008 Time Zone: GMT+2 Main Contribution: POIFS Browser 1.0 aTao Xiang - Technical writer ----------- From: China Participated since Aug, 2009 Time Zone: GMT+8 Main Contribution: NPOI 1.2 Chinese Tutorial -------------------------------------------------------------------------------- NPOI 1.2.3 - NPOI 1.2.5 -------------------------------------------------------------------------------- Antony - developer ------------------------------ From: Guangzhou, China Time Zone: GMT+8 Main Contribution: main code,bug fixing ,Excel2Html, Word2Html Christian Leutloff - developer ------------------------------ From: Germany Time Zone: GMT+1 Main Contribution: fix FXCop warnings, OOXML Jeff Stedfast - developer ------------------------------ From: Cambridge, MA, USA Time Zone: GMT Main contribution: Mono version of NPOI, naming conversion Leon Wang - developer ----------------------------- From: Xi'an, China Time Zone: GMT+8 Main contribution: NPOIFS/POIFS NPOI 2.0 -------------------------------------------------------------------------------- Tony Qu - chief developer ------------------------------- From: Shanghai, China Time Zone: GMT+8 Main Contribution: OpenXml4Net, OpenXmlFormats, NPOI.XSSF, NPOI.XWPF implementation Antony - developer ------------------------------ From: Guangzhou, China Time Zone: GMT+8 Main Contribution: XWPF implementation, OpenXmlFormats Christian Leutloff - developer ------------------------------ From: Germany Time Zone: GMT+1 Main Contribution: OpenXmlFormats, Excel 2007 comment read Jeff Stedfast - developer ------------------------------ From: Cambridge, MA, USA Time Zone: GMT Main contribution: Mono version of NPOI, enumeration changes and compilation optimization Paul Kratt - developer ------------------------------ From: Greater Milwaukee Area, Wisconsin, USA Time Zone: GMT Main contribution: CopyTo, CopySheet functions in HSSFSheet NPOI 2.1 -------------------------------------------------------------------------------- Tony Qu - main contributor Antony - fix some poi bugs Phil Rykoff - developer ------------------------------ Main contribution: XSSF bug fixing and feature implement NPOI 2.2 ~ 2.5.2 -------------------------------------------------------------------------------- Antony Tony Qu
