Как сохранить документ в PDF формат на C# и .NET
- Добавьте SautinSoft.Document из Nuget.
- Загрузите или создайте документ.
- Сохраните в формате PDF.
- Сохранить в файл:
// The file format will be detected automatically from the file extension: ".pdf". dc.Save(@"d:\Book.pdf");Чтобы не полагаться на расширение файла и гарантировать, что содержимое файла действительно PDF (Adobe Portable Format), Вы можете указать PdfSaveOptions в качестве второго параметра.
dc.Save(@"d:\Book.pdf", new PdfSaveOptions());В PdfSaveOptions Вы также можете установить различные параметры, влияющие на процесс сохранения.
dc.Save(@"d:\Book.pdf", new PdfSaveOptions() { Compliance = PdfCompliance.PDF_A1a, PreserveFormFields = true }); - Сохранить в поток:
// Let's save our document to a MemoryStream. using (MemoryStream ms = new MemoryStream()) { dc.Save(ms, new PdfSaveOptions() { PageIndex=0, PageCount=1, Compliance = PdfCompliance.PDF_A1a }); }
