Question

我有一个字符索引，想要获取包含该索引的页面的SET search_path=tmp; CREATE TABLE users ( id INTEGER NOT NULL, email VARCHAR(120), PRIMARY KEY (id), UNIQUE (email) ); INSERT INTO users VALUES(1,'Jim.Fake@nolive.co.uk'); INSERT INTO users VALUES(2,'osman.narnia@live.co.uk'); INSERT INTO users VALUES(3,'KimFake1@outlook.com'); INSERT INTO users VALUES(4,'jaakume@gmail.com'); INSERT INTO users VALUES(5,'omarblack@protonmail.com'); INSERT INTO users VALUES(6,'osman.everton@hotmail.com'); INSERT INTO users VALUES(7,'radoslaw@ganczarek.in'); INSERT INTO users VALUES(8,'kane1001@live.co.uk'); INSERT INTO users VALUES(9,'osman.soloking009@outlook.com'); INSERT INTO users VALUES(10,'Shum1945@fleckens.hu'); CREATE TABLE raffle ( id INTEGER NOT NULL, user_id INTEGER, colour VARCHAR(120), up1 VARCHAR(4), up2 VARCHAR(4), PRIMARY KEY (id), CONSTRAINT _color_up1_up2_uc UNIQUE (colour, up1, up2), FOREIGN KEY(user_id) REFERENCES users (id) ); INSERT INTO raffle VALUES(1,1,'Blue','7c4c','5c7e'); INSERT INTO raffle VALUES(2,1,'Pink','635d','853f'); INSERT INTO raffle VALUES(3,1,'Plum','5e80','7611'); INSERT INTO raffle VALUES(4,1,'Aqua','937c','1b75'); INSERT INTO raffle VALUES(5,2,'Navy','1d9a','8914'); INSERT INTO raffle VALUES(6,1,'Grey','d869','fc97'); INSERT INTO raffle VALUES(7,4,'Rose','5fee','b31f'); INSERT INTO raffle VALUES(8,1,'Ruby','d5b4','e749'); INSERT INTO raffle VALUES(9,2,'Teal','cf0b','3bf5'); INSERT INTO raffle VALUES(10,1,'Gold','98a7','3079'); INSERT INTO raffle VALUES(11,1,'Jade','5c69','66f8'); INSERT INTO raffle VALUES(12,1,'Lime','156f','6b34'); INSERT INTO raffle VALUES(13,1,'Blue','7da3','d95b'); INSERT INTO raffle VALUES(14,1,'Pink','a63e','b9b6'); INSERT INTO raffle VALUES(15,1,'Plum','d989','71a5'); INSERT INTO raffle VALUES(16,1,'Aqua','7372','0682'); /**** INSERT INTO raffle VALUES(17,9,'Navy','01b3','e444'); INSERT INTO raffle VALUES(18,1,'Grey','d679','0123'); INSERT INTO raffle VALUES(19,1,'Rose','5963','692d'); ... ***/。为了说明这个特定的用例，我正在运行句子验证规则（使用自然语言处理），我想在用户正在处理的整个页面上运行它们。所以：

Range

示例电话：

public static class ExtensionForDocument
{
    public static Range GetPage(this Document document, int characterIndex)
    {
        throw new NotImplementedException();
    }
}

我试过了：

    public void OnInspect(IRibbonControl control)
    {
        var selection = Application.Selection;
        var selectionRange = Application.ActiveDocument.GetPage(selection.Range.Start);
        // Process range here.
    }

部分不起作用。因此，获取实际页面的范围：

    public static Range GetPage(this Document document, int characterIndex)
    {
        var sectionCount = document.Sections.Count;

        for (var sectionIndex = 1; sectionIndex <= sectionCount; sectionIndex++)
        {
            var section = document.Sections[sectionIndex];
            var sectionRange = section.Range;
            if (characterIndex >= sectionRange.Start && characterIndex <= sectionRange.End)
            {
                return sectionRange;
            }
        }

        return null;
    }

但是在这些范围内，“开始”和“结束”表示页码，而不是字符索引。我也用书签尝试过相同的东西，因为我读到应该有“\ page”书签 - 但是没有任何书签。什么是正确的方法？

你的getPage（）非常接近解决方案。函数GoTo（）在range.Start和range.End中返回页面的第一个字符索引，它不返回页码。因此，要获得页面的开始和结束，您需要运行GoTo两次。

不是最好的代码。我在C＃中使用了一些Java代码约定，抱歉。

 public Word.Range getPageByCharacterIndex(int characterIndex) {
            var numberOfPages = (int)doc.Content.Information[Word.WdInformation.wdNumberOfPagesInDocument];
            int lastCharInDoc = doc.Range(0).End;

            Word.Range rangeStart = null; ;
            Word.Range rangeEnd = null;
            for (var p = 1; p <= numberOfPages; p++) {
                object what = Word.WdGoToItem.wdGoToPage;
                object which = Word.WdGoToDirection.wdGoToAbsolute;
                object count = p;
                rangeStart = doc.GoTo(ref what, ref which, ref count);
                object countPlusOne = p + 1;
                rangeEnd = doc.GoTo(ref what, ref which, ref countPlusOne);
                if (rangeStart.Start <= characterIndex && characterIndex <= rangeEnd.End) {
                    Word.Range result = doc.Range(rangeStart.Start, rangeEnd.End);
                    return result;
                }
            }
            // ¿is characterIndex in last page?  
            if (rangeEnd !=null & rangeEnd.Start <= characterIndex && characterIndex <= lastCharInDoc) {
                Word.Range result = doc.Range(rangeEnd.Start, lastCharInDoc);
                return result;
            }

            return null;
        }
