最近在研究winform打印文件，需要支持word，excel，ppt，pdf，图片这几种格式，不能依赖相关软件环境，研究后决定使用Aspose套件将相关文件全部转换成pdf后打印
WrodToPDF
使用Aspose.Word 11.9，需要配合licence文件破解
//去水印 string licenseFile = "Aspose.Words.lic"; if (File.Exists(licenseFile)) { Aspose.Words.License license = new Aspose.Words.License(); license.SetLicense(licenseFile); } //转换 Aspose.Words.Document doc = new Aspose.Words.Document(FileFullName); doc.Save(SaveFileName, Aspose.Words.SaveFormat.Pdf);
ExcelToPDF
使用Aspose.Cell 8.3（破解版本）
//转换 Workbook excel = new Workbook(FileFullName); excel.Save(SaveFileName, Aspose.Cells.SaveFormat.Pdf);
PPTToPDF
使用Aspose.Slides 16.9（需要配合代码破解）
//去水印 string[] stModule = new string[8] { "u0002u2006u2006u2003", "u0003u2006u2006u2003", "u0005u2005u2000u2003", "u0003u2000", "u000F", "u0002u2000", "u0003", "u0002" }; Assembly assembly = Assembly.GetAssembly(typeof(Aspose.Slides.License)); Type typeLic = null, typeIsTrial = null, typeHelper = null; foreach (Type type in assembly.GetTypes()) { if ((typeLic == null) && (type.Name == stModule[0])) { typeLic = type; } else if ((typeIsTrial == null) && (type.Name == stModule[1])) { typeIsTrial = type; } else if ((typeHelper == null) && (type.Name == stModule[2])) { typeHelper = type; } } if (typeLic == null || typeIsTrial == null || typeHelper == null) { throw new Exception(); } object lic = Activator.CreateInstance(typeLic); int findCount = 0; foreach (FieldInfo field in typeLic.GetFields(BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance)) { if (field.FieldType == typeLic && field.Name == stModule[3]) { field.SetValue(null, lic); ++findCount; } else if (field.FieldType == typeof(DateTime) && field.Name == stModule[4]) { field.SetValue(lic, DateTime.MaxValue); ++findCount; } else if (field.FieldType == typeIsTrial && field.Name == stModule[5]) { field.SetValue(lic, 1); ++findCount; } } foreach (FieldInfo field in typeHelper.GetFields(BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance)) { if (field.FieldType == typeof(bool) && field.Name == stModule[6]) { field.SetValue(null, false); ++findCount; } if (field.FieldType == typeof(int) && field.Name == stModule[7]) { field.SetValue(null, 128); ++findCount; } } if (findCount < 5) { throw new NotSupportedException("无效的版本"); } //转换 Presentation ppt = new Presentation(FileFullName); ppt.Save(SaveFileName, Aspose.Slides.Export.SaveFormat.Pdf);

使用Aspose.Pdf 9.4（需要配合代码破解）
//去水印 private const string Key = "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"; private static Stream LStream = (Stream)new MemoryStream(Convert.FromBase64String(Key)); var l = new Aspose.Pdf.License(); l.SetLicense(LStream); //转换 Document doc = new Document(); Page page = doc.Pages.Add(); Aspose.Pdf.Image image = new Aspose.Pdf.Image(); image.File = FileFullName; page.Paragraphs.Add(image); PrintFileName = OfficeUtil.CombinePDFPath(ConvertPDFName); doc.Save(PrintFileName);
PDF文件打印
使用Aspose.Pdf打印文件可以直接设置打印机名称，分数，方向d等
System.Drawing.Printing.PrinterSettings ps = new System.Drawing.Printing.PrinterSettings(); ps.PrinterName = PrinterName; ps.Copies = Copies; ps.Duplex = Direction; PdfViewer viewer = new PdfViewer(); viewer.BindPdf(PrintFileName); viewer.PrintDocumentWithSettings(ps); viewer.Close();
注：对于excel转换pdf后是没有表格线的，ppt转换pdf后打印会被截断，需要自己调整方向与纸张大小设置
