Delete contents of bookmark without deleting bookmark in ms word using c#

问题

In ms word2010 I have a bookmark with bookmark name: nameOfBookmark

Now the bookmark content could be anything from just text to a mix of pictures, tables and whatever you could think of putting in a word document.

The problem is as following: I've got my bookmark with some contents I want to delete. However each time I try to delete the contents it also deletes my bookmark which I want to keep.

I've tried this, which simply deletes the whole thing:

    public void cleanBookmark(string bookmark)
    {
        var start = currentDocument.Bookmarks[nameOfBookmark].Start;
        var end = currentDocument.Bookmarks[nameOfBookmark].End;
        Word.Range range = currentDocument.Range(start, end);
        range.Delete();
    }

I've also tried to set the range to this:

Word.Range range = currentDocument.Range(start +1, end -1);

But then I end up with a bookmark that still contains the first and the last character of the content I wanted to delete.

Well I wonder why I have to keep answering my own questions, please notify me if you think it could be something about the way I ask questions.

Anyway I found a solution after a bit more research and it seems like the thing I want simply can't be done or at least not the way I thought it could be done.

If you delete the contents of a bookmark it also deletes the bookmark. So what you have to do is to store the name and range of the bookmark in a local variable and then add the bookmark again after deleting it.

    public void cleanBookmark(string bookmark)
    {
        var start = currentDocument.Bookmarks[bookmark].Start;
        var end = currentDocument.Bookmarks[bookmark].End;
        Word.Range range = currentDocument.Range(start, end);
        range.Delete(); 
        //The Delete() only deletes text so if you got tables in the doc it leaves the tables empty. 
        //The following removes the tables in the current range.
        if (range.Tables.Count != 0)
        {
            for (int i = 1; i <= range.Tables.Count; i++)
            {
                range.Tables[i].Delete();
            }
        }
        currentDocument.Bookmarks.Add(bookmark, range);
    }

I have found that if you convert your text into a table and insert the single I beam bookmark in the cell where you need it to go, the table protects the bookmark even if you delete the content. Then once you have worked out all of your vba for the form, if you convert the form into a dotm, the users shouldn't have any issue with removing the bookmarks by accident and you having to troubleshoot the form to fix their mistake.

You can try this:

ActiveDocument.Bookmarks("name").Range.Characters.First.Delete

P.S.
Still trying to solve for multiple bookmarks.
