XmlNamespaceManager.AddNameSpace在本地计算机上正常运行，但在服务器上运行不正常

Question

我已经编写了一些代码来读取Word .dotx文件中的内容。在我的开发机器上一切都很好，可以读取文档内容但在服务器上代码会导致CPU使用率大幅增加，并且不会读取文档（原因不明）。

从Word .dotx文件中获取的XML示例：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document xmlns:wpc="http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

我的方法：

public static string TextFromWordXMLFile(string path){
  StringBuilder stringBuilder;    
  try {
       using (WordprocessingDocument wordprocessingDocument = 
              WordprocessingDocument.Open(path, false)) {
                NameTable nameTable = new NameTable();
                XmlNamespaceManager xmlNamespaceManager =
                  new XmlNamespaceManager(nameTable);
                xmlNamespaceManager.AddNamespace(
                  "w", "http://schemas.openxmlformats.org/wordprocessingml/2006/main");

       string wordprocessingDocumentText;
       using (StreamReader streamReader = new StreamReader(wordprocessingDocument
             .MainDocumentPart.GetStream())){
         wordprocessingDocumentText = streamReader.ReadToEnd();
       }

       stringBuilder = new StringBuilder(wordprocessingDocumentText.Length);
       XmlDocument xmlDocument = new XmlDocument(nameTable);
       xmlDocument.LoadXml(wordprocessingDocumentText);
       XmlNodeList paragraphNodes = xmlDocument.SelectNodes("//w:p", 
                                    xmlNamespaceManager);
       foreach (XmlNode paragraphNode in paragraphNodes) {
         XmlNodeList textNodes = paragraphNode.SelectNodes(".//w:t | .//w:tab | .//w:br",
                                 xmlNamespaceManager);
         foreach (XmlNode textNode in textNodes) {
           switch (textNode.Name) {
             case "w:t":
               stringBuilder.Append(textNode.InnerText);
               break;
             case "w:tab":
               stringBuilder.Append("\t");
               break;
             case "w:br":
               stringBuilder.Append("\v");
               break;
           }
         }
         stringBuilder.Append(Environment.NewLine);
         if (stringBuilder.Length > Length) break;
       }
    }
    return stringBuilder.ToString();
  } catch (IOException) {
     // This is likely to be that the file is in use because 
     // we're currently already opening it in word: ignore.
  }    
  return "";
}

任何帮助都会非常感激，因为我非常喜欢这个......

谢谢，

瑞恩。
