        IWpfTextView textView = AdaptersFactory.GetWpfTextView(textViewAdapter);
        textView.MouseHover += TextViewMouseHover;
    }

    private void TextViewMouseHover(object sender, MouseHoverEventArgs e)
    {
        IWpfTextView textView = (IWpfTextView)sender;

        // 获取当前鼠标位置的缓冲区位置
        SnapshotPoint? point = textView.BufferGraph.MapDownToFirstMatch(
            e.Position,
            PointTrackingMode.Positive,
            snapshot => !snapshot.IsInertial);

        if (point.HasValue)
        {
            ITextSnapshot snapshot = point.Value.Snapshot;

            // 获取当前鼠标位置的所有注释
            var comments = snapshot.GetIntersectingSpans(new SnapshotSpan(snapshot, new Span(point.Value.Position, 0)))
                                    .Where(span => span.GetText().StartsWith("//"));

            if (comments.Any())
            {
                // 鼠标悬停在注释上
                // 执行相应的操作
            }
        }
    }
}
