替换书签内容而不删除书签 [英] Replace bookmarks content without removing the bookmark

问题描述

我要替换书签的文本内容而不丢失书签.

I want to replace the text content of bookmarks without loosing the bookmark.

foreach(Bookmark b in document.Bookmarks)
{
    b.Range.Text = "newtext";  // text is set in document but bookmark is gone
}

我尝试在文本"设置之前设置书签的新范围"，但是仍然存在相同的问题.

I tried to set the new Range of the bookmark before the Text setting but I still have the same problem.

我还尝试使用document.Bookmarks.Add(name, range);重新添加书签，但是我无法创建range的实例.

I also tried to re-add the bookmark with document.Bookmarks.Add(name, range); but I can't create an instance of range.

推荐答案

我必须阅读书签并临时保存范围.我还必须添加一个已处理项目的列表，以避开一个无限循环.

I had to readd the bookmarks and save the range temporarily. I also had to add a list of processed items to evade an endless loop.

List<string> bookmarksProcessed = new List<string>();

foreach (Bookmark b in document.Bookmarks)
{
    if (!bookmarksProcessed.Contains(b.Name))
    {
        string text = getTextFromBookmarkName(b.Name);
        var newend = b.Range.Start + text.Length;
        var name = b.Name;
        Range rng = b.Range;
        b.Range.Text = text;
        rng.End = newend;
        document.Bookmarks.Add(name, rng);
        bookmarksProcessed.Add(name);
    }
}
