如何将WordOpenXML属性转换为System.IO.Packaging.Package？

问题描述：

我一直在使用Visual Studio 2008在C＃中构建一个Outlook 2010插件。我能够从Microsoft.Office.Interop.Outlook.Inspector对象中获得Microsoft.Office.Interop.Word.DocumentClass对象，该对象代表当前正在编辑的电子邮件。我知道这DocumentClass也用于其他各种情况（通常用于Microsoft Word扩展，毫不奇怪）。如何将WordOpenXML属性转换为System.IO.Packaging.Package？

该类有用地有一个名为WordOpenXML的属性，它似乎是构成.docx包的所有文件的XML表示形式，当将此Word文档保存为.docx时，它将保存到磁盘。

这种属性的一种方式将是非常有用的，如果它可以被转换为内存中的System.IO.Packaging.Package对象;即。反序列化它。有谁知道是否有一种简单的方法来做到这一点，还是我需要编写一些XML解析代码来手动执行？

jez，为什么赏金，如果你已经回答了你自己的问题？ –

我把赏金付诸行动后，我发现了它。 :-) – Jez

啊，明白了。是的，我打算建议在msdn上看看eric white的旧网站，我想我记得在那里看到了一个解决方案。很高兴看到它被发现并记录下来供将来参考。 –

我结束了修改一些代码，我在网上找到产生它转换WordOpenXML一个包，这是保存到磁盘的方法：

using System; 
using System.Xml; 
using System.Xml.XPath; 
using System.Text; 
using System.IO; 
using System.IO.Packaging; 

// [...] 
// Call like this: createPackageFromWordOpenXML(wordEditor.WordOpenXML, @"C:\outputFiles\testOut.docx"); 

/// <summary> 
/// Creates a ZIP package (ie. Word's .docx format) from a WordOpenXML string, which is saved to the file at the path specified. 
/// </summary> 
/// <param name="wordOpenXML">The WordOpenXML string to get the ZIP package data from.</param> 
/// <param name="filePath">The path of the file to save the ZIP package to.</param> 
private void createPackageFromWordOpenXML(string wordOpenXML, string filePath) 
{ 
    string packageXmlns = "http://schemas.microsoft.com/office/2006/xmlPackage"; 
    Package newPkg = System.IO.Packaging.ZipPackage.Open(filePath, FileMode.Create); 

    try 
    { 
     XPathDocument xpDocument = new XPathDocument(new StringReader(wordOpenXML)); 
     XPathNavigator xpNavigator = xpDocument.CreateNavigator(); 

     XmlNamespaceManager nsManager = new XmlNamespaceManager(xpNavigator.NameTable); 
     nsManager.AddNamespace("pkg", packageXmlns); 
     XPathNodeIterator xpIterator = xpNavigator.Select("//pkg:part", nsManager); 

     while (xpIterator.MoveNext()) 
     { 
      Uri partUri = new Uri(xpIterator.Current.GetAttribute("name", packageXmlns), UriKind.Relative); 

      PackagePart pkgPart = newPkg.CreatePart(partUri, xpIterator.Current.GetAttribute("contentType", packageXmlns)); 

      // Set this package part's contents to this XML node's inner XML, sans its surrounding xmlData element. 
      string strInnerXml = xpIterator.Current.InnerXml 
       .Replace("<pkg:xmlData xmlns:pkg=\"" + packageXmlns + "\">", "") 
       .Replace("</pkg:xmlData>", ""); 
      byte[] buffer = Encoding.UTF8.GetBytes(strInnerXml); 
      pkgPart.GetStream().Write(buffer, 0, buffer.Length); 
     } 

     newPkg.Flush(); 
    } 
    finally 
    { 
     newPkg.Close(); 
    } 
}

我转换这VB.Net，并增加了一个peice的处理与二进制附件。感谢您的出色工作！
