如何使用C＃反转ms-word文档中的所有单词？

Question

The document formatting should not change. Nothing change other than words order.

Document :

Word1 word2 word3 word2... -- END OF LINE OR PARAGRAPH
Word5 word1 word5 word4.....

After reversing should be like following

1droW 2drow 3drow 2drow... -- END OF LINE OR PARAGHRAPH
5droW 1drow 5drow 4drow..... 

Already I have this code to go through words one by one but I don't have any idea how to change without missing formatting.

string RT = "";


Word.Application wordObject = new Word.Application();
wordObject.Visible = false;

Word.Document docs = wordObject.Documents.Open(@"D:\ELAHE (J)\a.docx");

String strLine;
bool bolEOF = false;

docs.Characters[1].Select();

int index = 0;
do {

    object unit = Word.WdUnits.wdWord;
    object count = 1;
    wordObject.Selection.MoveEnd(ref unit, ref count);

    wordObject.Selection.InsertBefore("‭");
    strLine = wordObject.Selection.Text;
    RT += ++index + " - " + strLine + "\r\n"; 


    object direction = Word.WdCollapseDirection.wdCollapseEnd;
    wordObject.Selection.Collapse(ref direction);

    if (cnt++ > 100) break;

    if (wordObject.Selection.Bookmarks.Exists(@"\EndOfDoc")) bolEOF = true;
} while (!bolEOF);

docs.Close();
wordObject.Quit();
docs = null;
wordObject = null;

Just created a sample of how this can be done (C# 5.0, Word Interop v. 15 (Office 2013)). The code loops through each paragraph and reverses each word in a paragraph. The code includes a check for end-of-line symbols ( \\r ) to make sure that these are not reversed.

I'm not 100% sure that \\r is the only end-of-line symbol used by Word, so if you encounter other kinds, eg \\r\\n or something similar, it should be rather straight forward to include checks for these as well.

var wordApplication = new Application() { Visible = true };
var myDocument = wordApplication.Documents.Open(@"C:\Users\...\my.docx");

for (var i = 1; i <= myDocument.Paragraphs.Count; i++)
{
    var paragraph = myDocument.Paragraphs[i];
    var words = paragraph.Range.Words.Cast<Range>().Select(r => r.Text).ToList();

    // Empty paragraph -> continue
    if(words.Count == 1 && words[0] == "\r")
        continue;

    for (var j = 0; j < words.Count; j++)
    {
        var word = words[j];

        // Should not be reversed
        if(word == "\r")
            continue;

        var reversed = new string(word.Trim().Reverse().ToArray());

        words[j] = (word.EndsWith(" ")) ? reversed + " " : reversed;
    }

    paragraph.Range.Text = string.Join("", words);
}
