如何使用OpenXML SDK获取MS Word中超链接的绝对URI？

Question

A MS word file contains a link to local files (MS word, excel, visio ...), I used OpenXML to get absolute URI of linking local files. But I only get filename.

Could you give me some advice?

  using (WordprocessingDocument document = WordprocessingDocument.Open(docxFile, true))
{
    Body body = document.MainDocumentPart.Document.Body;

    //-----------------------------------------------
    DocumentFormat.OpenXml.Wordprocessing.Hyperlink hLink = body.Descendants<DocumentFormat.OpenXml.Wordprocessing.Hyperlink>().FirstOrDefault();
    if (hLink != null)
    {
        // get hyperlink's relation Id (where path stores)
        string relationId = hLink.Id;
        if (relationId != string.Empty)
        {
            // get current relation
            HyperlinkRelationship hr = document.MainDocumentPart.HyperlinkRelationships.Where(a => a.Id == relationId).FirstOrDefault();
            if (hr != null)
            { 
                string path = hr.Uri.AbsolutePath; //exception
            }
        }
    }
}

Answer 1

just use hr.Uri.ToString() method to get the path

According to MSDN: "The AbsolutePath property contains the path information that the server uses to resolve requests for information."
