使用Open XML SDK 2.0向Excel 2007中的单元格添加超链接

另一种可能性(我使用的)是使用 HYPERLINK Excel公式。我需要在每个单元格中创建单独的超链接,但单元格必须显示不同的文本(我必须在单元格中显示跟踪编号,但每个跟踪编号都有一个超链接,指向运营商的网站,并且必须处理多个运营商)。

一旦我实例化了一个单独的单元,公式就以这种方式应用到每个单元(毫无疑问有很多种方法):

// ...
Cell cell1 = new Cell(){ CellReference = "A1", StyleIndex = (UInt32Value)1U, DataType = CellValues.InlineString };
CellValue cellValue1 = new CellValue();

CellFormula cellFormula1 = new CellFormula() { Space = SpaceProcessingModeValues.Preserve };
cellFormula1.Text = @"HYPERLINK(""http://www.theclash.com"", ""Radio Clash"")";
cellValue1.Text = "Radio Clash";
cell1.Append(cellFormula1);
cell1.Append(cellValue1);
// append cell, etc.

这样,我就可以为每个单元格创建单独的超链接和文本。另外,链接将以默认字体颜色显示,除非您引用了蓝色字体的样式。

希望这有帮助。

我可以使用 System.IO.Packaging 代码:

private void HyperlinkCreate(PackagePart part, XmlNamespaceManager nsm, XmlNode _cellElement, string CellAddress)
{
        Uri _hyperlink = new Uri("http://www.yahoo.com");
        XmlNode linkParent = _cellElement.OwnerDocument.SelectSingleNode("//d:hyperlinks", nsm);
        if (linkParent == null)
        {
            // create the hyperlinks node
            linkParent = _cellElement.OwnerDocument.CreateElement("hyperlinks", @"http://schemas.openxmlformats.org/spreadsheetml/2006/main");
            XmlNode prevNode = _cellElement.OwnerDocument.SelectSingleNode("//d:conditionalFormatting", nsm);
            if (prevNode == null)
            {
                prevNode = _cellElement.OwnerDocument.SelectSingleNode("//d:mergeCells", nsm);
                if (prevNode == null)
                {
                    prevNode = _cellElement.OwnerDocument.SelectSingleNode("//d:sheetData", nsm);
                }
            }
            _cellElement.OwnerDocument.DocumentElement.InsertAfter(linkParent, prevNode);
        }
        string searchString = string.Format("./d:hyperlink[@ref = '{0}']", CellAddress);
        XmlElement linkNode = (XmlElement)linkParent.SelectSingleNode(searchString, nsm);
        XmlAttribute attr;
        if (linkNode == null)
        {
            linkNode = _cellElement.OwnerDocument.CreateElement("hyperlink", @"http://schemas.openxmlformats.org/spreadsheetml/2006/main");
            // now add cell address attribute
            linkNode.SetAttribute("ref", CellAddress);
            linkParent.AppendChild(linkNode);
        }

        attr = (XmlAttribute)linkNode.Attributes.GetNamedItem("id", @"http://schemas.openxmlformats.org/officeDocument/2006/relationships");
        if (attr == null)
        {
            attr = _cellElement.OwnerDocument.CreateAttribute("r", "id", @"http://schemas.openxmlformats.org/officeDocument/2006/relationships");
            linkNode.Attributes.Append(attr);
        }                     

        PackageRelationship relationship = null;
        string relID = attr.Value;
        if (relID == "")
            relationship = part.CreateRelationship(_hyperlink, TargetMode.External, @"http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink");
        else
        {
            relationship = part.GetRelationship(relID);
            if (relationship.TargetUri != _hyperlink)
                relationship = part.CreateRelationship(_hyperlink, TargetMode.External, @"http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink");
        }
        attr.Value = relationship.Id;
}

然后我使用OpenXMLSDK2.0翻译了这段代码,但它不起作用。似乎是 AddHyperlinkRelationship 方法实际上没有将关系添加到 Res 文件。我不知道为什么,但在我看来,它确实像个虫子。

private void HyperlinkCreate(PackagePart part, XmlNamespaceManager nsm, XmlNode _cellElement, string CellAddress)
    {

WorksheetPart workSheetPart = ExcelUtilities.GetWorkSheetPart(mWorkBookPart, "Program");
            Uri hyperlinkUri = new Uri("http://www.yahoo.com", UriKind.Absolute);

            Hyperlinks hyperlinks = workSheetPart.Worksheet.Descendants<Hyperlinks>().FirstOrDefault();

            // Check to see if the <x:hyperlinks> element exists; if not figure out 
            // where to insert it depending on which elements are present in the Worksheet
            if (hyperlinks == null)
            {
                // Create the hyperlinks node
                hyperlinks = new Hyperlinks();

                OpenXmlCompositeElement prevElement = workSheetPart.Worksheet.Descendants<ConditionalFormatting>().FirstOrDefault();
                if (prevElement == null)
                {
                    prevElement = workSheetPart.Worksheet.Descendants<MergeCells>().FirstOrDefault();
                    if (prevElement == null)
                    {
                        // No FirstOrDefault needed since a Worksheet requires SheetData or the excel doc will be corrupt
                        prevElement = workSheetPart.Worksheet.Descendants<SheetData>().First();
                    }
                }
                workSheetPart.Worksheet.InsertAfter(hyperlinks, prevElement);
            }
            Hyperlink hyperlink = hyperlinks.Descendants<Hyperlink>().Where(r => r.Reference.Equals(CellAddress)).FirstOrDefault();
            if (hyperlink == null)
            {
                hyperlink = new Hyperlink() { Reference = CellAddress, Id = string.Empty };

            }

            HyperlinkRelationship hyperlinkRelationship = null;
            string relId = hyperlink.Id;
            if (relId.Equals(string.Empty))
            {
                hyperlinkRelationship = workSheetPart.AddHyperlinkRelationship(hyperlinkUri, true);
            }
            else
            {
                hyperlinkRelationship = workSheetPart.GetReferenceRelationship(relId) as HyperlinkRelationship;
                if (!hyperlinkRelationship.Uri.Equals(hyperlinkUri))
                {
                    hyperlinkRelationship = workSheetPart.AddHyperlinkRelationship(hyperlinkUri, true);
                }
            }
            hyperlink.Id = hyperlinkRelationship.Id;
            hyperlinks.AppendChild<Hyperlink>(hyperlink);
            workSheetPart.Worksheet.Save();     
        }

您应该将它添加到接受超链接的对象中,例如单元格,而不是工作表。像这样的事情应该对你有用:

using DocumentFormat.OpenXml.Spreadsheet;
using DocumentFormat.OpenXml;

{
    public class GeneratedClass
    {
        // Creates an Worksheet instance and adds its children.

            worksheet1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");

            cellValue1.Text = "0";

            cell1.Append(cellValue1);

            row1.Append(cell1);

            worksheet1.Append(sheetDimension1);
            worksheet1.Append(sheetViews1);
            worksheet1.Append(sheetFormatProperties1);
            worksheet1.Append(sheetData1);
            worksheet1.Append(hyperlinks1);
            worksheet1.Append(pageMargins1);
            return worksheet1;
        }


    }
