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
