c# - 在 .Net c# 中使用 OpenXML 在页脚中插入图像

Question

我正在使用 OpenXml 创建一个 word 文档报告，并想使用 AddExternalRelationship 将图像添加到页脚中，但没有得到突破。

如果有人能提供帮助，我们将不胜感激。

    protected void Page_Load(object sender, System.EventArgs e)
    {
        string fileName = "C:\\Report\\Report_" + System.Guid.NewGuid().ToString() + ".docx";
        using (WordprocessingDocument package = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
        {
            this.CreateParts(package);
        }
    }

    private void CreateParts(WordprocessingDocument document)
    {
        ExtendedFilePropertiesPart extendedFilePropertiesPart1 = document.AddNewPart<ExtendedFilePropertiesPart>("rId3");
        GenerateExtendedFilePropertiesPart1Content(extendedFilePropertiesPart1);
        /*********************************Code for generating the main Document content *****************************/
        MainDocumentPart mainDocumentPart1 = document.AddMainDocumentPart();
        Document document1 = new Document();
        Body body1 = new Body();

        SectionProperties sectionProperties1 = new SectionProperties() { RsidR = "00350EC0", RsidSect = "0025134C" };
        FooterReference footerReference1 = new FooterReference() { Type = HeaderFooterValues.Default, Id = "rId9" };
        PageSize pageSize1 = new PageSize() { Width = (UInt32Value)11906U, Height = (UInt32Value)16838U };
        PageMargin pageMargin1 = new PageMargin() { Top = 1440, Right = (UInt32Value)1440U, Bottom = 1440, Left = (UInt32Value)1440U, Header = (UInt32Value)708U, Footer = (UInt32Value)708U, Gutter = (UInt32Value)0U };
        Columns columns1 = new Columns() { Space = "708" };
        TitlePage titlePage1 = new TitlePage();
        DocGrid docGrid1 = new DocGrid() { LinePitch = 360 };

        sectionProperties1.Append(footerReference1);
        sectionProperties1.Append(pageSize1);
        sectionProperties1.Append(pageMargin1);
        sectionProperties1.Append(columns1);
        sectionProperties1.Append(titlePage1);
        sectionProperties1.Append(docGrid1);

        document1.Append(body1);
        mainDocumentPart1.Document = document1;

        /*********************************End of Code for generating the main Document content *****************************/

        FooterPart footerPart1 = mainDocumentPart1.AddNewPart<FooterPart>("rId9");
        GenerateFooterPart1Content(footerPart1);

        ImagePart imagePart1 = footerPart1.AddImagePart("image/png", "rId2");
        imagePart1.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/image",
            new System.Uri("C:\\YourFile.png", System.UriKind.RelativeOrAbsolute), "rId1");

        SetPackageProperties(document);
    }

请看下面我用来完成任务的代码。 我将 ExternalRelationShip 添加到页脚的 imagePart 而不是 FooterPart。

protected void Page_Load(object sender, System.EventArgs e)
{
    string fileName = "C:\\Report\\Report_" + System.Guid.NewGuid().ToString() + ".docx";
    using (WordprocessingDocument package = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
    {
        this.CreateParts(package);
    }
}

private void CreateParts(WordprocessingDocument document)
{
    ExtendedFilePropertiesPart extendedFilePropertiesPart1 = document.AddNewPart<ExtendedFilePropertiesPart>("rId3");
    GenerateExtendedFilePropertiesPart1Content(extendedFilePropertiesPart1);
    /*********************************Code for generating the main Document content *****************************/
    MainDocumentPart mainDocumentPart1 = document.AddMainDocumentPart();
    Document document1 = new Document();
    Body body1 = new Body();

    SectionProperties sectionProperties1 = new SectionProperties() { RsidR = "00350EC0", RsidSect = "0025134C" };
    FooterReference footerReference1 = new FooterReference() { Type = HeaderFooterValues.Default, Id = "rId9" };
    PageSize pageSize1 = new PageSize() { Width = (UInt32Value)11906U, Height = (UInt32Value)16838U };
    PageMargin pageMargin1 = new PageMargin() { Top = 1440, Right = (UInt32Value)1440U, Bottom = 1440, Left = (UInt32Value)1440U, Header = (UInt32Value)708U, Footer = (UInt32Value)708U, Gutter = (UInt32Value)0U };
    Columns columns1 = new Columns() { Space = "708" };
    TitlePage titlePage1 = new TitlePage();
    DocGrid docGrid1 = new DocGrid() { LinePitch = 360 };

    sectionProperties1.Append(footerReference1);
    sectionProperties1.Append(pageSize1);
    sectionProperties1.Append(pageMargin1);
    sectionProperties1.Append(columns1);
    sectionProperties1.Append(titlePage1);
    sectionProperties1.Append(docGrid1);

    document1.Append(body1);
    mainDocumentPart1.Document = document1;

    /*********************************End of Code for generating the main Document content *****************************/

    FooterPart footerPart1 = mainDocumentPart1.AddNewPart<FooterPart>("rId9");
    GenerateFooterPart1Content(footerPart1);

    footerPart1.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/image",
           new System.Uri("<URL to the Image>", System.UriKind.Absolute), "rFTimg"); //rFTimg -> should be same as imageData1'id in GenerateFooterPart1Content

    SetPackageProperties(document);
}

    private void GenerateFooterPart1Content(FooterPart footerPart1)
    {
        Run run = new Run();
        Picture picture = new Picture();

        Footer footer1 = new Footer();

        Paragraph paragraph85 = new Paragraph() { RsidParagraphAddition = "0025134C", RsidRunAdditionDefault = "00D71D07" };
        ParagraphProperties paragraphProperties85 = new ParagraphProperties();
        ParagraphStyleId paragraphStyleId85 = new ParagraphStyleId() { Val = "Footer" };

        paragraphProperties85.Append(paragraphStyleId85);
        paragraph85.Append(paragraphProperties85);

        V.Shape shape1 = new V.Shape() { Id = "_x0000_s7170", Style = "width:456pt;height:31.5pt;mso-position-horizontal-relative:page;mso-position-vertical-relative:page", WrapCoordinates = "-33 0 -33 21086 21600 21086 21600 0 -33 0", Type = "#_x0000_t75" };
        V.ImageData imageData1 = new V.ImageData() { Title = "Word_Footer_Brad_v1", RelationshipId = "rFTimg" };
        shape1.Append(imageData1);
        picture.Append(shape1);
        run.Append(picture);
        paragraph85.Append(run);

        footer1.Append(paragraph85);
        footerPart1.Footer = footer1;

    }
