[英]Add Hyperlink to Cell in Excel 2007 Using Open XML SDK 2.0
我似乎找不到任何有關如何使用Open XML SDK 2.0在Excel 2007中將超鏈接添加到單元格的文檔或代碼示例。 我正在使用以下代碼,但是我缺少一個步驟嗎?
WorksheetPart workSheetPart = ExcelUtilities.GetWorkSheetPart(mWorkBookPart, "Program");
workSheetPart.AddHyperlinkRelationship(new Uri("http://www.google.com", UriKind.Absolute), true);
workSheetPart.Worksheet.Save();
mWorkBookPart.Workbook.Save();
然后,當我嘗試打開Excel文檔時,它說文件已損壞,因為找不到超鏈接的關系ID。 您如何設置或創建該關系ID?
(我曾經使用過)另一種可能性是對Excel使用HYPERLINK公式。 我需要在每個單元格中創建單獨的超鏈接,但是這些單元格必須顯示不同的文本,(我必須在單元格中顯示跟蹤號,但每個跟蹤號都具有到運營商站點的超鏈接,並且必須處理多個運營商)。
一旦我實例化了一個單元格,便以這種方式將公式應用於每個單元格(無疑有很多方法):
// ...
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.
這樣,我就可以為每個單元格創建單獨的超鏈接和文本。 順便說一句,除非您引用帶有藍色字體的樣式,否則鏈接將以默認字體顏色顯示。
希望這可以幫助。
我能夠使用System.IO.Packaging
代碼將超鏈接添加到單元格:
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Open XML SDK 2.0轉換了此代碼,但它不起作用。 看來AddHyperlinkRelationship
方法實際上並未將關系添加到.rels文件中。 我不確定為什么,但是對我來說似乎確實是個錯誤。
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();
}
您應該將其添加到接受超鏈接(例如單元格)的對象,而不是工作表。 這樣的事情應該為您工作:
using DocumentFormat.OpenXml.Spreadsheet;
using DocumentFormat.OpenXml;
namespace GeneratedCode
{
public class GeneratedClass
{
// Creates an Worksheet instance and adds its children.
public Worksheet GenerateWorksheet()
{
Worksheet worksheet1 = new Worksheet(){ MCAttributes = new MarkupCompatibilityAttributes(){ Ignorable = "x14ac" } };
worksheet1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");
worksheet1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
worksheet1.AddNamespaceDeclaration("x14ac", "http://schemas.microsoft.com/office/spreadsheetml/2009/9/ac");
SheetDimension sheetDimension1 = new SheetDimension(){ Reference = "A1" };
SheetViews sheetViews1 = new SheetViews();
SheetView sheetView1 = new SheetView(){ TabSelected = true, WorkbookViewId = (UInt32Value)0U };
sheetViews1.Append(sheetView1);
SheetFormatProperties sheetFormatProperties1 = new SheetFormatProperties(){ DefaultRowHeight = 14.4D, DyDescent = 0.3D };
SheetData sheetData1 = new SheetData();
Row row1 = new Row(){ RowIndex = (UInt32Value)1U, Spans = new ListValue<StringValue>() { InnerText = "1:1" }, DyDescent = 0.3D };
Cell cell1 = new Cell(){ CellReference = "A1", StyleIndex = (UInt32Value)1U, DataType = CellValues.SharedString };
CellValue cellValue1 = new CellValue();
cellValue1.Text = "0";
cell1.Append(cellValue1);
row1.Append(cell1);
sheetData1.Append(row1);
Hyperlinks hyperlinks1 = new Hyperlinks();
Hyperlink hyperlink1 = new Hyperlink(){ Reference = "A1", Id = "rId1" };
hyperlinks1.Append(hyperlink1);
PageMargins pageMargins1 = new PageMargins(){ Left = 0.7D, Right = 0.7D, Top = 0.75D, Bottom = 0.75D, Header = 0.3D, Footer = 0.3D };
worksheet1.Append(sheetDimension1);
worksheet1.Append(sheetViews1);
worksheet1.Append(sheetFormatProperties1);
worksheet1.Append(sheetData1);
worksheet1.Append(hyperlinks1);
worksheet1.Append(pageMargins1);
return worksheet1;
}
}
}
最簡單的方法是使用HyperLink公式器,但是默認情況下鏈接不是藍色的,這就是為什么要設置styleIndex的原因。
private Cell BuildHyperlinkCell(string url) =>
new Cell
{
DataType = new EnumValue<CellValues>(CellValues.String),
CellFormula = new CellFormula($"HyperLink(\"{url}\")"),
StyleIndex = 4u
};
