如何仅从word文件中获取标题及其副标题

我假设您将 title 和 st 声明为字符串，每次迭代循环时，旧值都会被当前值替换。如果使用列表，则可以向其添加文本和副标题。然后，您可以轻松地用它们做您想做的事情。

List<String> title = new List<String>();
List<String> st = new List<String>();
foreach (Microsoft.Office.Interop.Word.Paragraph paragraph in oMyDoc.Paragraphs )
        {
            Microsoft.Office.Interop.Word.Style style = paragraph.get_Style() as Microsoft.Office.Interop.Word.Style;
            string styleName = style.NameLocal;
            string text = paragraph.Range.Text;

            if (styleName == "Title")
            {
                title.Add(text.ToString());
            }
            else if (styleName == "Subtitle")
            {
                st.Add(text.ToString());
            }
            else if (styleName=="Heading 1")
            {
                heading1[h1c] = text.ToString()+"'n";

            }
}

如果你想得到整个大纲（如目录中的内容），"标题"并不是很可靠，因为所有样式都可以重命名/复制。因此，其他一些样式，如"H1"或"标题1"（中文单词"Heading1"）可以充当标题并显示在目录和导航面板中。

我什至看到"正常"在文档中充当标题。这让我放弃了使用样式来查找标题。

尝试段落。大纲级别改为。它的值范围从WdOutlineLevel.wdOutlineLevel1到9（意味着它是某种"标题"），并以WdOutlineLevel.wdOutlineLevelBodyText结尾（意味着它只是文本正文）。

这是我的代码。我甚至建立了一个树状的标题列表（每行一个标题）。

public static class WordBridge
{
    public static Dictionary<WdOutlineLevel, string> Level2Spaces = new Dictionary<WdOutlineLevel, string>()
    {
        {WdOutlineLevel.wdOutlineLevel1, ""},
        {WdOutlineLevel.wdOutlineLevel2, " "},
        {WdOutlineLevel.wdOutlineLevel3, "  "},
        {WdOutlineLevel.wdOutlineLevel4, "   "},
        {WdOutlineLevel.wdOutlineLevel5, "    "},
        {WdOutlineLevel.wdOutlineLevel6, "     "},
        {WdOutlineLevel.wdOutlineLevel7, "      "},
        {WdOutlineLevel.wdOutlineLevel8, "       "},
        {WdOutlineLevel.wdOutlineLevel9, "        "},
        {WdOutlineLevel.wdOutlineLevelBodyText, "         "},
    };
    public static string GetOutlines(object? sender, Document currentWordDoc)
    {
        var sb = new StringBuilder();
        var countFinished = 0;
        foreach (Paragraph paragraph in currentWordDoc.Paragraphs)
        {
            countFinished++;
            (sender as BackgroundWorker)?.ReportProgress(countFinished);
            if (paragraph.OutlineLevel == WdOutlineLevel.wdOutlineLevelBodyText)
                continue;
            if (Level2Spaces.ContainsKey(paragraph.OutlineLevel))
                sb.Append(Level2Spaces[paragraph.OutlineLevel] + paragraph.Range.Text);
        }
        return sb.ToString();
    }
}

我可能会在不久的将来把它变成一棵真正的树。顺便说一句，如果您没有进度条，请删除报告进度内容。但是由于单线程，它真的很慢。
