获取word文档的页面

Question

我正在尝试通过 Microsoft.Office.Interop.Word 获取 MSWord 文档的所有页面（我在 VS2012 中使用 C#）。我想得到的是 List Pages，其中 index 是页数。我理解（至少我是这么认为的）没有直接的方法可以做到这一点。所以我想出了类似的东西：

        List<String> Pages = new List<String>();
        int NumberOfPreviousPage = -1;
        int NumberOfPage = -1;
        string InnerText = "";
        for (int i = 0; i < Doc.Paragraphs.Count; i++)
        {
            Paragraph CurrentParagraph = Doc.Paragraphs[i + 1];
            InnerText = CurrentParagraph.Range.Text;
            NumberOfPage = CurrentParagraph.Range.get_Information(WdInformation.wdActiveEndPageNumber);
            if (NumberOfPage == NumberOfPreviousPage)
                Pages[Pages.Count - 1] += String.Format("\r\n{0}", InnerText);
            else
            {
                Pages.Add(InnerText);
                NumberOfPreviousPage = NumberOfPage;
            }
        }

但是，当算法到达从一页开始并在另一页结束的段落时，它决定该段落应该在下一页。我想在页面之间拆分这一段，但我不知道如何检测我必须在哪里进行拆分。

一个更简单的解决方案。

伪代码：

• 获取页数。
• 对于每一页：
  • 查找本页最后一个字符索引和最后一页最后一个字符索引之间的字符。

实施：

    /// <summary>
    /// Reads each page of the word document into a string and returns the list of the page strings.
    /// </summary>
    public static IEnumerable<string> ReadPages(string filePath)
    {
        ICollection<string> pageStrings = new List<string>();
        Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
        Document doc = app.Documents.Open(filePath);

        long pageCount = doc.ComputeStatistics(Microsoft.Office.Interop.Word.WdStatistic.wdStatisticPages);
        int lastPageEnd = 0; // The document starts at 0.
        for ( long i = 0; i < pageCount; i++)
        {
            // The "range" of the page break. This actually is a range of 0 elements, both start and end are the 
            // location of the page break.
            Range pageBreakRange = app.Selection.GoToNext(Microsoft.Office.Interop.Word.WdGoToItem.wdGoToPage);
            string currentPageText = doc.Range(lastPageEnd, pageBreakRange.End).Text;
            lastPageEnd = pageBreakRange.End;
            pageStrings.Add(currentPageText);
        }
        return pageStrings;
    }

最终，我完成了这个，并且它有效（它很蹩脚，它很丑，但它做了它应该做的）：

public string[] GetPagesDoc(object Path)
    {
        List<string> Pages = new List<string>();

        // Get application object
        Microsoft.Office.Interop.Word.Application WordApplication = new Microsoft.Office.Interop.Word.Application();

        // Get document object
        object Miss = System.Reflection.Missing.Value;
        object ReadOnly = false;
        object Visible = false;
        Document Doc = WordApplication.Documents.Open(ref Path, ref Miss, ref ReadOnly, ref Miss, ref Miss, ref Miss, ref Miss, ref Miss, ref Miss, ref Miss, ref Miss, ref Visible, ref Miss, ref Miss, ref Miss, ref Miss);

        // Get pages count
        Microsoft.Office.Interop.Word.WdStatistic PagesCountStat = Microsoft.Office.Interop.Word.WdStatistic.wdStatisticPages;
        int PagesCount = Doc.ComputeStatistics(PagesCountStat, ref Miss);

        //Get pages
        object What = Microsoft.Office.Interop.Word.WdGoToItem.wdGoToPage;
        object Which = Microsoft.Office.Interop.Word.WdGoToDirection.wdGoToAbsolute;
        object Start;
        object End;
        object CurrentPageNumber;
        object NextPageNumber;

        for (int Index = 1; Index < PagesCount + 1; Index++)
        {
            CurrentPageNumber = (Convert.ToInt32(Index.ToString()));
            NextPageNumber = (Convert.ToInt32((Index+1).ToString()));

            // Get start position of current page
            Start = WordApplication.Selection.GoTo(ref What, ref Which, ref CurrentPageNumber, ref Miss).Start;

            // Get end position of current page                                
            End = WordApplication.Selection.GoTo(ref What, ref Which, ref NextPageNumber, ref Miss).End;

            // Get text
            if (Convert.ToInt32(Start.ToString()) != Convert.ToInt32(End.ToString()))
                Pages.Add(Doc.Range(ref Start, ref End).Text);
            else
                Pages.Add(Doc.Range(ref Start).Text);
        }
            return Pages.ToArray<string>();
    }
