I know you’ve been thirsty for some code, so here we go.
I was dumfounded at the absence of “working” code samples for injecting a hyperlink using Open XML 2.0 on google and bing. I don’t consider samples that reference missing sealed constant classes to be “working”…
This one injects a hyperlink at the end of the word doc and will not inject it more than once:
//c:Program Files (x86)Open XML SDKV2.0libDocumentFormat.OpenXml.dll
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Wordprocessing;
using (WordprocessingDocument wdPackage =
WordprocessingDocument.Open(stream, true))
{
//add the url
string urlLabel = “Text To Display”;
System.Uri uri = new Uri(“http://something.urlencoded.org”);
bool urlExists = false;
foreach (HyperlinkRelationship hRel in wdPackage.MainDocumentPart.HyperlinkRelationships)
{
if (hRel.Uri == uri)
{
urlExists = true;
break;
}
}
if (!urlExists)
{
MainDocumentPart mainPart = wdPackage.MainDocumentPart;
HyperlinkRelationship rel = mainPart.AddHyperlinkRelationship(uri, true);
string relationshipId = rel.Id;
Paragraph newParagraph = new Paragraph(
new Hyperlink(
new ProofError() { Type = ProofingErrorValues.GrammarStart },
new Run(
new RunProperties(
new RunStyle() { Val = “Hyperlink” }),
new Text(urlLabel)
)) { History = OnOffValue.FromBoolean(true), Id = relationshipId });
Paragraph p = mainPart.Document.Body.Elements<DocumentFormat.OpenXml.Wordprocessing.Paragraph>().Last();
mainPart.Document.Body.InsertAfter<Paragraph>(newParagraph, p);
mainPart.Document.Save();
}
wdPackage.Close();
}
