Word Interop - 如何确定一个 word 文档是否在 Header/footer 中有页码

Question

我想知道 Word 文档在 Header/Footer 中是否有页码，在 C# 中使用 Interop.Word。

我已经走到这一步了

try
{
    foreach (Section SectionObj in DocObj.Sections)
    {          
        foreach (HeaderFooter HeaderObj in SectionObj.Footers)
        {
            if (HeaderObj.Exists && (HeaderObj.Shapes.Count > 0 || !(string.IsNullOrEmpty(HeaderObj.Range.Text) || HeaderObj.Range.Text.Equals("\r"))))
            {
                if(HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleNumberInDash 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleUppercaseLetter 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleUppercaseRoman 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleNumberInCircle 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleLowercaseRoman 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleLowercaseLetter 
                || HeaderObj.PageNumbers.NumberStyle == WdPageNumberStyle.wdPageNumberStyleHindiLetter1)
                {
                    PageNumber = true;
                }
            }
        }
    }
}
catch (Exception e) { }

但是检查无法确定它是否是页码。如何判断是否有页码？

Answer 1

您应该使用 PageNumbers.Count 属性检查节的页眉和页脚。

    private bool HeaderOrFooterHasPageNumber(Word.HeaderFooter headOrFooter)
    {
        if (headOrFooter != null)
            return headOrFooter.PageNumbers.Count > 0;
        else
            return false;
    }

你可以这样称呼它...

        bool hasNumberPages = false;

        Word.Document doc = WordApp.ActiveDocument;
        try
        {
            Word.HeaderFooter headOrFooter = null;
            Word.Section section = null;

            for (int i = 1; i <= doc.Sections.Count; i++)
            {
                try
                {
                    section = doc.Sections[i];
                    if(section != null)
                    {
                        headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;

                        headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterEvenPages];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;

                        headOrFooter = section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;

                        headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;

                        headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterEvenPages];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;

                        headOrFooter = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterFirstPage];
                        hasNumberPages = HeaderOrFooterHasPageNumber(headOrFooter);
                        if (hasNumberPages)
                            break;
                    }
                }
                finally
                {
                    if(headOrFooter != null)
                    {
                        Marshal.ReleaseComObject(headOrFooter);
                        headOrFooter = null;
                    }

                    if (section != null)
                        Marshal.ReleaseComObject(section);
                }
            }
        }
        finally
        {
            if (doc != null)
                Marshal.ReleaseComObject(doc);
        }
