我有一些代码，希望有人可以帮助我。我想要实现的是使用嵌入的 XSLT 文件将基于 Infopaths XML 的表单转换为 Word 2007 文档以进行转换。

代码：

XPathNavigator nav = MainDataSource.CreateNavigator();
string fieldProject = nav.SelectSingleNode("//my:Project", NamespaceManager).Value;
string fieldQuote = nav.SelectSingleNode("//my:QuoteNumber", NamespaceManager).Value;
string fieldDate = nav.SelectSingleNode("//my:Date", NamespaceManager).Value;


// Define variables for the word template to use and file to create
string wordTemplateFilePath = @"\\2003server\common\OIF Proposals\TemplateFile\Interiors Letter Template.docx";
string wordPrintFilePath = @"\\2003server\common\OIF Proposals\Ben Johnson Ltd Furniture Proposal - " + fieldProject + " - " + fieldQuote + " - " + fieldDate + ".docx";

// Copy the template to create a new docx file
File.Copy(wordTemplateFilePath, wordPrintFilePath, true);

// Crack open the package
Package packWordPrint = Package.Open(wordPrintFilePath, FileMode.Open, FileAccess.ReadWrite);

// Retrieve the document.xml part of the new docx file
PackagePart part = packWordPrint.GetPart(new Uri("/word/document.xml", UriKind.Relative));

// Retrieve the xsl to use to transform the InfoPath form into document.xml
XslCompiledTransform trans = new XslCompiledTransform();
Stream xslTemplate = this.Template.OpenFileFromPackage("transform.xsl");
XmlReader xslTemplateReader = XmlReader.Create(xslTemplate);
trans.Load(xslTemplateReader);

// Create a StreamWriter to be able to write to the stream of the part
using (StreamWriter partStream = new StreamWriter(part.GetStream(FileMode.Open, FileAccess.Write)))
{
    // Transform the InfoPath form and save the XML into the stream for the part
    trans.Transform(this.MainDataSource.CreateNavigator(), null, partStream);

    // Close the stream of the part
    partStream.Close();
}

// Write changes to the package
packWordPrint.Flush();

// Close the package
packWordPrint.Close();

而且我收到大约八分之一的以下错误：

System.IO.IOException
The process cannot access the file '\\2003server\common\OIF Proposals\Ben Johnson Ltd Furniture Proposal - ABC123 - 123 - 2010-08-19.docx' because it is being used by another process.

   at Microsoft.Office.InfoPath.Internal.ButtonEventHost.OnButtonClick(DocActionEvent pEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._ButtonEventSink_SinkHelper.OnClick(DocActionEvent pEvent)

必须有一种明智的方法来处理或防止错误，只是无法理解它。

我想我一定不能正确地关闭某个流？

非常感谢对代码的任何指针/更改。

最好使用它using来确保包已关闭：

using (Package packWordPrint = Package.Open(wordPrintFilePath, FileMode.Open, FileAccess.ReadWrite))
{
    ...
}

并删除该packWordPrint.Close();声明。

我认为问题实际上是AV。使用上述解决方案时，我仍然遇到 IOException 错误，我将继续按照它们自己的权利将它们实现为正确的，但是一旦我将写入目录放在 AV 扫描仪的异常列表中，我就停止了错误.

重构您的代码，使其在文件关闭时更加高效且更具确定性。这应该会有所帮助。注意：我在 SO 编辑器中进行了重新考虑，因此可能存在拼写错误、缺少大括号等。

另外，我不确定您还在使用 packWordPrint 做什么，但它真的需要打开 ReadWrite 吗？看起来你只是从中读取，所以打开它 ReadOnly 会更聪明，你不需要在最后调用 Flush。

XPathNavigator nav = MainDataSource.CreateNavigator();
string fieldProject = nav.SelectSingleNode("//my:Project", NamespaceManager).Value;
string fieldQuote = nav.SelectSingleNode("//my:QuoteNumber", NamespaceManager).Value;
string fieldDate = nav.SelectSingleNode("//my:Date", NamespaceManager).Value;

// Retrieve the xsl to use to transform the InfoPath form into document.xml
Stream xslTemplate = this.Template.OpenFileFromPackage("transform.xsl");
XmlReader xslTemplateReader = XmlReader.Create(xslTemplate);

XslCompiledTransform trans = new XslCompiledTransform();
trans.Load(xslTemplateReader);

// Define variables for the word template to use and file to create
string wordTemplateFilePath = @"\\2003server\common\OIF Proposals\TemplateFile\Interiors Letter Template.docx";
string wordPrintFilePath = string.Format(@"\\2003server\common\OIF Proposals\Ben Johnson Ltd Furniture Proposal - {0} - {1} - {2}.docx",fieldProject, fieldQuote,fieldDate);

// Copy the template to create a new docx file
File.Copy(wordTemplateFilePath, wordPrintFilePath, true);

// Crack open the package
using (Package packWordPrint = Package.Open(wordPrintFilePath, FileMode.Open, FileAccess.ReadWrite))
{

  // Retrieve the document.xml part of the new docx file
  PackagePart part = packWordPrint.GetPart(new Uri("/word/document.xml", UriKind.Relative));

  // Create a StreamWriter to be able to write to the stream of the part
  using (StreamWriter partStream = new StreamWriter(part.GetStream(FileMode.Open, FileAccess.Write)))
  {
      // Transform the InfoPath form and save the XML into the stream for the part
      trans.Transform(this.MainDataSource.CreateNavigator(), null, partStream);
  }

  // Write changes to the package
  packWordPrint.Flush();

}
