How to load a DOCX document in C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load a DOCX document from file or stream.
  1. Load from a file: 
    
DocumentCore dc = DocumentCore.Load(@"d:\Book.docx");
    The dc represents the document "Book.docx" loaded in memory. The file format is detected automatically from the file extension: ".docx" .

    After loading you'll get the document presented as the Tree Of Objects, where the root node is DocumentCore class.

    To guarantee that a loadable content is really DOCX and set some loading options, use DocxLoadOptions as 2nd parameter.

    
DocumentCore dc = DocumentCore.Load(@"d:\Book.docx", new DocxLoadOptions());
  2. Load using a memory: 
    
            // Let us say we already have a DOCX document as array of bytes.
            byte[] docxBytes = null;
            // docxBytes = ...
            
            DocumentCore dc = null;
            using (MemoryStream docxStream = new MemoryStream(docxBytes))
            {
                dc = DocumentCore.Load(docxStream, new DocxLoadOptions());
            }
            // Here we can do with our document 'dc' anything we need.
