Word 转成pdf及打印的开源方案支持xp

Word转成pdf、打印的方案几乎没有免费开源的方案,现在提供一个通过LibreOffice实现的方案

操作依赖LibreOffice需要安装,点此下载老版本

5.4.7.2是最后一个支持xp的 版本如需xp要请安装此版本

LibreOffice官方介绍

LibreOffice 是一款开放源代码的自由免费全能办公软件,可运行于 Microsoft Windows, GNU/Linux 以及 macOS 等操作系统上。它包含了 Writer, Calc, Impress, Draw, Math 以及 Base 等组件,可分别用于文本文档、电子表格、幻灯片演示文稿、绘图文档、数学公式编辑、数据库管理等工作。

LibreOffice 采用对企业和个人用户均免费的 MPL 2.0 授权协议。您可以自由分发该软件,无需支付授权费用(但您仍然可以付费获得经认证的专业支持)。它的源代码完全公开,任何人都可以参与软件的开发和维护。

一、通过进程的方式

1.Word打印

  public void PrintWordFile(string file, string printerName){if (string.IsNullOrEmpty(file)) throw new Exception("Invalid parameters passed to convert word function.");if (!File.Exists(file)) throw new FileNotFoundException($"The file passed to the convert word process ({file}) could not be found.");var fileInfo = new FileInfo(file);if (fileInfo.Extension.ToLower() != ".doc" && fileInfo.Extension.ToLower() != ".docx")throw new ArgumentOutOfRangeException($"The file type passed to the convert word process is an invalid type ({fileInfo.Extension}).");var libreOfficePath = Path.Combine(LibreOfficePath, "swriter.exe");if (!File.Exists(libreOfficePath)) throw new FileNotFoundException("It seems that LibreOffice is not where it should be, please ensure the path exists.");var procStartInfo = new ProcessStartInfo(libreOfficePath, $@"--headless --pt ""{printerName}"" ""{file}"""){RedirectStandardOutput = true,RedirectStandardError = true,UseShellExecute = false,CreateNoWindow = true,WorkingDirectory = Environment.CurrentDirectory};Process process = new Process() { StartInfo = procStartInfo };// Attach event handlers to capture output and error streamsprocess.OutputDataReceived += (sender, args) => Console.WriteLine("OUT: " + args.Data);process.ErrorDataReceived += (sender, args) => Console.WriteLine("ERR: " + args.Data);process.Start();// Start reading the output asynchronouslyprocess.BeginOutputReadLine();process.BeginErrorReadLine();process.WaitForExit();if (process.ExitCode != 0){throw new LibreOfficeFailedException(process.ExitCode);}}

2.Word转成PDF

  public string ConvertWordFile(string file, string outputDirectory){if (string.IsNullOrEmpty(file) || string.IsNullOrEmpty(outputDirectory)) throw new Exception("Invalid parameters passed to convert word function.");if (!File.Exists(file)) throw new FileNotFoundException($"The file passed to the convert word process ({file}) could not be found.");if (!Directory.Exists(outputDirectory)) throw new DirectoryNotFoundException($"The output folder passed to the convert word process ({outputDirectory}) does not exist.");if (outputDirectory.EndsWith(@"\")) outputDirectory = outputDirectory.TrimEnd('\\');var fileInfo = new FileInfo(file);if (fileInfo.Extension.ToLower() == ".doc" && fileInfo.Extension.ToLower() == ".docx") throw new ArgumentOutOfRangeException($"The file type passed to the convert word process is an invalid type ({fileInfo.Extension}).");var outputFile = outputDirectory + @"\" + Path.GetFileNameWithoutExtension(fileInfo.Name) + ".pdf";if (File.Exists(outputFile)) File.Delete(outputFile);var libreOfficePath = Path.Combine(LibreOfficePath, "swriter.exe");if (!File.Exists(libreOfficePath)) throw new FileNotFoundException("It seems that LibreOffice is not where it should be, please ensure the path exists.");var procStartInfo = new ProcessStartInfo(libreOfficePath, $@"--headless --convert-to pdf:writer_pdf_Export ""{file}"" --outdir ""{outputDirectory}"""){RedirectStandardOutput = true,UseShellExecute = false,CreateNoWindow = true,WorkingDirectory = Environment.CurrentDirectory};Process process = new Process() { StartInfo = procStartInfo };process.Start();process.WaitForExit();if (process.ExitCode != 0)throw new LibreOfficeFailedException(process.ExitCode);if (!File.Exists(outputFile)) throw new FileNotFoundException("The convert to word process has failed to convert the file!");return outputFile;}public class LibreOfficeFailedException : Exception{public LibreOfficeFailedException(int exitCode) : base($"LibreOffice has failed with {exitCode}") { }}

二、通过cli库调用,下附代码
