PDF文件打印

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]
            {
                "\u0002\u2006\u2006\u2003",
                "\u0003\u2006\u2006\u2003",
                "\u0005\u2005\u2000\u2003",
                "\u0003\u2000",
                "\u000F",
                "\u0002\u2000",
                "\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]))

                    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])
                {

                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);

                    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
