Question

I am trying to extract all the words in a Word document. I am able to do it all in one go as follows…

Word.Application word = new Word.Application();
doc = word.Documents.Open(@"C:\SampleText.doc");
doc.Activate();

foreach (Word.Range docRange in doc.Words) // loads all words in document
{
    IEnumerable<string> sortedSubstrings = Enumerable.Range(0, docRange.Text.Trim().Length)
        .Select(i => docRange.Text.Substring(i))
        .OrderBy(s => s.Length < 3 ? s : s.Remove(2, Math.Min(s.Length - 2, 2)));

    wordPosition =
        (int)
        docRange.get_Information(
            Microsoft.Office.Interop.Word.WdInformation.wdFirstCharacterColumnNumber);

    foreach (var substring in sortedSubstrings)
    {
        index = docRange.Text.IndexOf(substring) + wordPosition;
        charLocation[index] = substring;
    }
}

However I would have preferred to load the document one line at a time… is it possible to do so?

I can load it by paragraph however I am unable to iterate through the paragraphs to extract all words.

foreach (Word.Paragraph para in doc.Paragraphs)
{
    foreach (Word.Range docRange in para) // Error: type Word.para is not enumeranle**
    {
        IEnumerable<string> sortedSubstrings = Enumerable.Range(0, docRange.Text.Trim().Length)
            .Select(i => docRange.Text.Substring(i))
            .OrderBy(s => s.Length < 3 ? s : s.Remove(2, Math.Min(s.Length - 2, 2)));

        wordPosition =
            (int)
            docRange.get_Information(
                Microsoft.Office.Interop.Word.WdInformation.wdFirstCharacterColumnNumber);

        foreach (var substring in sortedSubstrings)
        {
            index = docRange.Text.IndexOf(substring) + wordPosition;
            charLocation[index] = substring;
        }

    }
}

I would suggest following the code on this page here

The crux of it is that you read it with a Word.ApplicationClass (Microsoft.Interop.Word) object, although where he’s getting the “Doc” object is beyond me. I would assume you create it with the ApplicationClass.

EDIT: Document is retrieved by calling this:

Word.Document doc = wordApp.Documents.Open(ref file, ref nullobj, ref nullobj,
                                      ref nullobj, ref nullobj, ref nullobj,
                                      ref nullobj, ref nullobj, ref nullobj,
                                      ref nullobj, ref nullobj, ref nullobj);

Sadly the formatting of the code on the page I linked wasn’t all to easy.

EDIT2: From there you can loop through doc paragraphs, however as far as I can see there is no way of looping through lines. I would suggest using some pattern matching to find linebreaks.

In order to extract the text from a paragraph, use Word.Paragraph.Range.Text, this will return all the text inside a paragraph. Then you must search for linebreak characters. I’d use string.IndexOf().

Alternatively, if by lines you want to extract one sentence at a time, you can simply iterate through Range.Sentences
