C# xml文件utf-8转gb2312问题 - Web 开发 / XML/SOAP

我要在网页上上传一个XML文件，我在C#中写了一个验证XML文件格式的方法： 
private bool ValidateXml(string xmlFilePath) 
  { 
  string xsdPath = Request.PhysicalApplicationPath + @"Files\example\rcpt.xsd"; 
  //使用xmlReader验证XML格式 
  // Set the validation settings. 
  XmlReaderSettings settings = new XmlReaderSettings(); 
  settings.ValidationType = ValidationType.Schema; 
  settings.Schemas.Add(null, xsdPath); 
  settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema; 
  settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings; 
  settings.ValidationEventHandler += new ValidationEventHandler(settings_ValidationEventHandler); 

  // Create the XmlReader object. 
  XmlReader reader = XmlReader.Create(xmlFilePath, settings); 

  // Parse the file. 
  try 
  { 
  while (reader.Read()); 
  } 
  catch (Exception ex) 
  { 

  lblMessage.Text = "出现异常!" + ex.Message; 
  return false; 
  }&nbs
