在C#中操作Word 2007文档XML

Question

我试图在C#中操纵Word 2007文档的XML.我已经设法找到并操纵了我想要的节点,但现在我似乎无法弄清楚如何将其保存回来.这是我正在尝试的:

// Open the document  from memoryStream
Package pkgFile = Package.Open(memoryStream, FileMode.Open, FileAccess.ReadWrite);
PackageRelationshipCollection pkgrcOfficeDocument = pkgFile.GetRelationshipsByType(strRelRoot);

foreach (PackageRelationship pkgr in pkgrcOfficeDocument)
{
    if (pkgr.SourceUri.OriginalString == "/")
    {
        Uri uriData = new Uri("/word/document.xml", UriKind.Relative);

        PackagePart pkgprtData = pkgFile.GetPart(uriData);

        XmlDocument doc = new XmlDocument();
        doc.Load(pkgprtData.GetStream());

        NameTable nt = new NameTable();
        XmlNamespaceManager nsManager = new XmlNamespaceManager(nt);
        nsManager.AddNamespace("w", nsUri);

        XmlNodeList nodes = doc.SelectNodes("//w:body/w:p/w:r/w:t", nsManager);

        foreach (XmlNode node in nodes)
        {
            if (node.InnerText == "{{TextToChange}}")
            {
                node.InnerText = "success";
            }
        }


        if (pkgFile.PartExists(uriData))
        {
            // Delete template "/customXML/item1.xml" part
            pkgFile.DeletePart(uriData);
        }
        PackagePart newPkgprtData = pkgFile.CreatePart(uriData, "application/xml");
        StreamWriter partWrtr = new StreamWriter(newPkgprtData.GetStream(FileMode.Create, FileAccess.Write));

        doc.Save(partWrtr);
        partWrtr.Close();
    }
}   

pkgFile.Close();

我收到错误'内存流不可扩展'.有任何想法吗？

我建议您使用Open XML SDK而不是自己破解格式.
