Question

我试图通过FtpWebRequest将档案从A站点下载并上载到B站点。

我面临的问题是,在我下载Im的档案时,数据没有增加8820份。

这里我使用的是:

public FtpFile Download(string path)
{
  string fullpath = ConstructFullpath(path);

  FtpWebRequest request = (FtpWebRequest)WebRequest.Create(fullpath);
  request.Method = WebRequestMethods.Ftp.DownloadFile;
  // login
  request.Credentials = new NetworkCredential(Username, Password);  

  FtpWebResponse response = (FtpWebResponse)request.GetResponse();
  Stream responseStream = request.GetResponse().GetResponseStream();

  byte[] data = new byte[20000];
  int length = responseStream.Read(data, 0, data.Length);
  responseStream.Close();

  FtpFile file = new FtpFile(path, data, length);
  return file;
}

public bool Upload(FtpFile file)
{
  if (!DirectoryExists(GetDirectory(file.Path)))
  {
    CreateDirectory(GetDirectory(file.Path));
  }

  string fullpath = ConstructFullpath(file.Path);
  FtpWebRequest request = (FtpWebRequest)WebRequest.Create(fullpath);
  request.Method = WebRequestMethods.Ftp.UploadFile;
  request.Credentials = new NetworkCredential(Username, Password);


  Stream stream = request.GetRequestStream();
  stream.Write(file.Data, 0, file.Length);
  stream.Close();

  FtpWebResponse response = (FtpWebResponse)request.GetResponse();
  return true;
}

The First image shows the source directory. The second image shows the destination directory.

“源网络名录”</p

The destination web directory I have tried saving the files locally and have the same result.

byte[] data = new byte[20000];
int length = responseStream.Read(data, 0, data.Length);
responseStream.Close();

不能保证所有数据都用单一电话阅读,你永远不能依靠这些数据。您请在<代码>Read 返回时填写数据。

如果你重新使用“NET”4,Stream.CopyTo,就很容易做到:

MemoryStream ms = new MemoryStream();
responseStream.CopyTo(ms);

请注意,你还应使用<条码>,使用<>条码>,而不是明确关闭资源,包括<条码> FtpWebResponse。
