How to load a DOC (Word 97 - 2003) document in C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load a DOC document from file or stream.

  1. Load from a file: 
    
DocumentCore dc = DocumentCore.Load(@"..\..\example.doc");
    The dc represents the document "example.doc" loaded in memory. The file format is detected automatically from the file extension: ".doc" .

    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 DOC and set some loading options, use DocLoadOptions as 2nd parameter.

    
DocumentCore dc = DocumentCore.Load(@"..\..\example.doc", new DocLoadOptions());
  2. Load using a MemoryStream: 
    
            // Assume that we already have a DOC (Word 97-2003) document as bytes array.
            byte[] fileBytes = File.ReadAllBytes(@"..\..\example.doc");

            DocumentCore dc = null;

            // Create a MemoryStream
            using (MemoryStream ms = new MemoryStream(fileBytes))
            {
                // Load a document from the MemoryStream.
                // Specifying DocLoadOptions we explicitly set that a loadable document is DOC.
                dc = DocumentCore.Load(ms, new DocLoadOptions());
            }
            if (dc != null)
                Console.WriteLine("Loaded successfully!");
