我有这段代码，我从 sql 数据库生成 xml 文件：

    int counter;
    int counter2;
private void GenerovaniVse()
{
  SqlConnection con = new SqlConnection("Data Source=****");
  string strSQL = "select w.KOD_....";                
  SqlDataAdapter dt = new SqlDataAdapter(strSQL, con);
  DataSet ds = new DataSet("ITEMS");
  dt.Fill(ds, "ITEM");
  FileStream strFileName = File.Create(@"C:\\Users\\L\\Desktop\\" + (counter++) + ".xml");
  XmlWriterSettings settings = new XmlWriterSettings();
  settings.Encoding = Encoding.Unicode;

  using (XmlWriter xmlWriter = XmlWriter.Create(strFileName, settings))
    {
      ds.WriteXml(xmlWriter);
      xmlWriter.Close();
    }
}

并将此文件上传到 ftp 的代码：

private void Upload()
 {
   FileInfo f = new FileInfo("C:\\Users\\L\\Desktop\\" + (counter2) + ".xml");
   long original_vel = f.Length; 
   FtpWebRequest request = (FtpWebRequest)WebRequest.Create(*****);
   request.Method = WebRequestMethods.Ftp.GetFileSize;
   request.Method = WebRequestMethods.Ftp.UploadFile;
   request.Credentials = new NetworkCredential("***", "***");

   StreamReader sourceStream = new StreamReader(??????);
   byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
   sourceStream.Close();
   request.ContentLength = fileContents.Length;
   long ftp_vel = request.ContentLength; //velikost souboru na ftp      
   Stream requestStream = request.GetRequestStream();
   requestStream.Write(fileContents, 0, fileContents.Length);
   requestStream.Close();
   FtpWebResponse response = (FtpWebResponse)request.GetResponse();
                counter2++;
                response.Close();                         
}

问题出在：strmfile.Close(); 但是现在当我将 xml 复制到 ftp 时，ftp 上的文件比原始 xml 更小……在原始 xml 上我有 Unicode，而 ftp 文件中没有任何代码……

strFileName在函数中完成写入后，您可能需要关闭它GenerovaniVse。
