我正在用 .NET C# 编写一个 Web 服务，它接收一个对象，将其转换为 xml，应用一个 XSLT 模板，运行转换，并返回一个 MS 工作文件。
这是该函数的代码：
public static HttpResponseMessage Transform(object data)
{
var response = new HttpResponseMessage(HttpStatusCode.OK);
StringWriter stringWriter = new StringWriter();
XmlWriter xmlWriter = XmlWriter.Create(stringWriter);
var applicationDirectory = AppDomain.CurrentDomain.BaseDirectory;
var xsltPath = applicationDirectory + @"\Reporting\Files\Template.xslt";
var templatePath = applicationDirectory + @"\Reporting\Files\Template.docx";
var xmlObject = new System.Xml.Serialization.XmlSerializer(data.GetType());
MemoryStream stream;
using (stream = new MemoryStream())
{
var sw = new StreamWriter(stream);
xmlObject.Serialize(stream, data);
stream.Position = 0;
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(xsltPath);
using (XmlReader xmlReader = XmlReader.Create(stream))
{
transform.Transform(xmlReader, xmlWriter);
XmlDocument newWordContent = new XmlDocument();
newWordContent.LoadXml(stringWriter.ToString());
var outputPath = applicationDirectory + @"\Reporting\Temp\temp.docx";
System.IO.File.Copy(templatePath, outputPath, true);
using (WordprocessingDocument output = WordprocessingDocument.Open(outputPath, true))
{
Body updatedBodyContent = new Body(newWordContent.DocumentElement.InnerXml);
output.MainDocumentPart.Document.Body = updatedBodyContent;
output.MainDocumentPart.Document.Save();
}
response.Content = new StreamContent(new FileStream(outputPath, FileMode.Open, FileAccess.Read));
response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
response.Content.Headers.ContentDisposition.FileName = outputPath;
}
}
return response;
}
当我提出请求时，它会给我一个没有数据的 word 文件。
我在使用 (XmlReader xmlReader = XmlReader.Create(stream)) 处设置了一个断点。运行该行后，xmlReader 的值为 {None}。
我还试图避免为提高效率而创建 XML 文件（因此是 MemoryStream）。
知道为什么这不起作用吗？有没有更好的方法来实现这一点？
谢谢，格尔森
