How to save a document in a desired format using C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load or Create a document.
  3. Save to a desired format.

Document .Net supports these formats:

PDF DOCX RTF HTML Text Image
Create/Read/Write Create/Read/Write Create/Read/Write Create/Read/Write Create/Read/Write Create/Read(OCR)/Write

Assume that we already loaded or created a document inside our DocumentCore class.

To save a document into a file, a single line is enough.

In this example, the method Save() automatically detects a saving format (PDF in this case) from the extension ".pdf":


            // Save our document 'dc' into a PDF file.
            dc.Save(@"d:\Book.pdf");

In most cases you will want to explicitly set the saving format and set some saving options. Given this point, the method Save() has several overloads and accepts SaveOptions as 2nd parameter.

For example, to explicitly save a document in HTML-fixed format:


            // Save our document 'dc' into HTML-fixed format.
            dc.Save(@"d:\Menu.html", new HtmlFixedSaveOptions()
            {
                CssExportMode = CssExportMode.Inline,
                PageBorder = false,
                EmbedImages = true
            });

All save options are derived from the base abstract class SaveOptions : PdfSaveOptions , DocxSaveOptions , HtmlFixedSaveOptions , HtmlFlowingSaveOptions , RtfSaveOptions etc.

Save to a memory:


            using (MemoryStream msRtf = new MemoryStream())
            {
                // Save our document in RTF format to a stream.
                dc.Save(msRtf, new RtfSaveOptions());
            }
