Import doc and docx files in .Net and C#

Question

I'm writing a text editor and I want to add the possibility to import .doc and .docx files. I know that I could use OLE Automation, but if I use a recent OLE library, it won't work with those people with an older version of Word, and if instead I use an older version, it won't be able to read .docx files. Any ideas? Thanks

EDIT: Another solution would be that, like my application works with HTML and RTF, convert .doc and .docx files with command line to one of these formats, something like this: http://www.snee.com/bobdc.blog/ 2007/09/using-word-for-command-line-co.html

I hope the text editor your building is a winform app? We wouldn't want you to run into a server-side problem: support.microsoft.com/kb/257757 — Jeremy Thompson

It's works with the Office 2003 PIA, tested in my computer running Office 2010:

using System.IO;
using System.Reflection;
using Microsoft.Office.Interop.Word;

public string GetHtmlFromDoc(string path)
    var wordApp = new Application {Visible = false};

//Cargar documento
            object srcPath = path;
            var wordDoc = wordApp.Documents.Open(ref srcPath);

            //Guardarlo en HTML
            string destPath = Path.Combine(Path.GetTempPath(), "word" + (new Random().Next()) + ".html");
            if (wordDoc != null)
            {
                object oDestPath = destPath;
                object exportFormat = WdSaveFormat.wdFormatHTML;
                wordDoc.SaveAs(ref oDestPath, ref exportFormat);
            }

            //Cerrar
            wordDoc.Close();
            wordApp.Quit();

            //Comprobar que el archivo existe);
            if (File.Exists(destPath))
            {
               return File.ReadAllText(destPath, Encoding.Default);
}
return null;
}
