C# Open XML HTML 到 DOCX 间距

MrM*_*att 1 c# asp.net export ms-word export-to-word

我一直在我的网站上工作，并尝试创建导出到 Word 的功能。导出效果很好，将 HTML 字符串转换为 DOCX。

我正在尝试弄清楚如何调整行距。默认情况下，Word 添加 8pt 后间距并将行间距设置为双倍。我更喜欢 0 和 Single。

这是我创建的用于保存 Word 文档的函数：

private static void SaveDOCX(string fileName, string BodyText, bool isLandScape, double rMargin, double lMargin, double bMargin, double tMargin)
{
    string htmlSectionID = "Sect1";
    //Creating a word document using the the Open XML SDK 2.0
    WordprocessingDocument document = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document);

    //create a paragraph
    MainDocumentPart mainDocumenPart = document.AddMainDocumentPart();
    mainDocumenPart.Document = new DocumentFormat.OpenXml.Wordprocessing.Document();
    Body documentBody = new Body();
    mainDocumenPart.Document.Append(documentBody);


    MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes("<html><head></head><body>" + BodyText + "</body></html>"));

    // Create alternative format import part.
    AlternativeFormatImportPart formatImportPart = mainDocumenPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Html, htmlSectionID);

    //ms.Seek(0, SeekOrigin.Begin);

    // Feed HTML data into format import part (chunk).
    formatImportPart.FeedData(ms);
    AltChunk altChunk = new AltChunk();
    altChunk.Id = htmlSectionID;

    mainDocumenPart.Document.Body.Append(altChunk);

    /*
     inch equiv = 1440 (1 inch margin)
     */
    double width = 8.5 * 1440;
    double height = 11 * 1440;

    SectionProperties sectionProps = new SectionProperties();
    PageSize pageSize;
    if (isLandScape)
    {
        pageSize = new PageSize() { Width = (UInt32Value)height, Height = (UInt32Value)width, Orient = PageOrientationValues.Landscape };
    }
    else
    {
        pageSize = new PageSize() { Width = (UInt32Value)width, Height = (UInt32Value)height, Orient = PageOrientationValues.Portrait };
    }

    rMargin = rMargin * 1440;
    lMargin = lMargin * 1440;
    bMargin = bMargin * 1440;
    tMargin = tMargin * 1440;

    PageMargin pageMargin = new PageMargin() { Top = (Int32)tMargin, Right = (UInt32Value)rMargin, Bottom = (Int32)bMargin, Left = (UInt32Value)lMargin, Header = (UInt32Value)360U, Footer = (UInt32Value)360U, Gutter = (UInt32Value)0U };

    sectionProps.Append(pageSize);
    sectionProps.Append(pageMargin);
    mainDocumenPart.Document.Body.Append(sectionProps);

    //Saving/Disposing of the created word Document
    document.MainDocumentPart.Document.Save();
    document.Dispose();
}

在搜索中，我发现了这段代码：

SpacingBetweenLines spacing = new SpacingBetweenLines() { Line = "240", LineRule = LineSpacingRuleValues.Auto, Before = "0", After = "0" };

我已将其放置在函数中的很多位置，但我似乎找不到附加此设置的正确位置。

我致力于尝试在代码中设置间距的函数，但无法删除间距。我决定尝试创建一个模板 Word 文档并在该文档中设置间距。

我复制 template.docx 文件，创建我将使用的文件，然后使用下面调整后的函数添加 HTML 字符串：

private static void SaveDOCX(string fileName, string BodyText, bool isLandScape, double rMargin, double lMargin, double bMargin, double tMargin)
{
    WordprocessingDocument document = WordprocessingDocument.Open(fileName, true);
    MainDocumentPart mainDocumenPart = document.MainDocumentPart;

    //Place the HTML String into a MemoryStream Object
    MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes("<html><head></head><body>" + BodyText + "</body></html>"));

    //Assign an HTML Section for the String Text
    string htmlSectionID = "Sect1";

    // Create alternative format import part.
    AlternativeFormatImportPart formatImportPart = mainDocumenPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Html, htmlSectionID);

    // Feed HTML data into format import part (chunk).
    formatImportPart.FeedData(ms);
    AltChunk altChunk = new AltChunk();
    altChunk.Id = htmlSectionID;

    //Clear out the Document Body and Insert just the HTML string.  (This prevents an empty First Line)
    mainDocumenPart.Document.Body.RemoveAllChildren();
    mainDocumenPart.Document.Body.Append(altChunk);

    /*
     Set the Page Orientation and Margins Based on Page Size
     inch equiv = 1440 (1 inch margin)
     */
    double width = 8.5 * 1440;
    double height = 11 * 1440;

    SectionProperties sectionProps = new SectionProperties();
    PageSize pageSize;
    if (isLandScape)
        pageSize = new PageSize() { Width = (UInt32Value)height, Height = (UInt32Value)width, Orient = PageOrientationValues.Landscape };
    else
        pageSize = new PageSize() { Width = (UInt32Value)width, Height = (UInt32Value)height, Orient = PageOrientationValues.Portrait };

    rMargin = rMargin * 1440;
    lMargin = lMargin * 1440;
    bMargin = bMargin * 1440;
    tMargin = tMargin * 1440;

    PageMargin pageMargin = new PageMargin() { Top = (Int32)tMargin, Right = (UInt32Value)rMargin, Bottom = (Int32)bMargin, Left = (UInt32Value)lMargin, Header = (UInt32Value)360U, Footer = (UInt32Value)360U, Gutter = (UInt32Value)0U };

    sectionProps.Append(pageSize);
    sectionProps.Append(pageMargin);
    mainDocumenPart.Document.Body.Append(sectionProps);

    //Saving/Disposing of the created word Document
    document.MainDocumentPart.Document.Save();
    document.Dispose();
}

通过使用模板文件，行距是正确的。

对于那些可能会发现此函数有用的人，以下是调用该函数的代码：

string filePath = "~/Content/Exports/Temp/";

string WordTemplateFile = HttpContext.Current.Server.MapPath("/Content/Templates/WordTemplate.docx");
string DestinationPath = HttpContext.Current.Server.MapPath(filePath);
string NewFileName = DOCXFileName + ".docx";

string destFile = System.IO.Path.Combine(DestinationPath, NewFileName);

System.IO.File.Copy(WordTemplateFile, destFile, true);

SaveDOCX(destFile, HTMLString, isLandScape, rMargin, lMargin, bMargin, tMargin);
