Question

我正在使用以下代码从FTP服务器下载文件。但无论如何，我总是会收到超时信息。

ftpo    = System.Net.WebRequest::Create("ftp://myserver.com/subFolder/filename.txt");
request = ftpo;

credential = new System.Net.NetworkCredential(_user, _password);
request.set_Credentials(credential);
request.set_KeepAlive(false);
request.set_Method(_ftpMethod);
request.set_UsePassive(true);
request.set_UseBinary(true);
request.set_Timeout(600000);
request.set_ReadWriteTimeout(600000);
ftpResponse         = request.GetResponse();
response            = ftpResponse;
reader = new System.IO.StreamReader(response.GetResponseStream());
if(reader)
{
    readString = reader.ReadToEnd();
}
if(readString)
{
    writer = new System.IO.StreamWriter(_destination);
    writer.Write(readString);
    writer.Flush();
    writer.Close();
}

错误消息

操作已经超时。

该文件为9kB。通过Filezilla下载它需要不到1秒。超时设置为10分钟。

导致此消息的原因是什么？关于如何调试它的任何想法（我无法访问FTP服务器）。

更新：在C＃中，相同的代码运行良好。

FtpWebRequest ftpRequest;
            var request = WebRequest.Create("ftp://server.com/folder/file.txt");
            ftpRequest = (FtpWebRequest) request;

            request.Credentials = new NetworkCredential("", "");
            request.Method = "RETR";
            ftpRequest.KeepAlive = false;
            ftpRequest.UsePassive = true;
            ftpRequest.UseBinary = true;
            FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse();
            var reader = new StreamReader(response.GetResponseStream());
            var result = "";
            if(reader != null)
            {
                result = reader.ReadToEnd();
                var writer = new StreamWriter(@"C:\temp\outfile.txt");
                writer.Write(result);
                writer.Flush();
                writer.Close();
            }
