我们有一个 OpenVMS (VMS) Alpha 服务器，我需要访问它才能通过 FTP 传输文件。问题是它不支持FtpWebRequest启动连接时使用的命令（ftp://192.168.xx.xx），除了 FtpWebRequest 之外，我还可以使用其他 FTP 功能吗？
我之前一直在 Windows 和 Unix 环境中使用我的代码，但这是我第一次在 VMS 操作系统上执行此操作，我还可以使用命令提示符通过 FTP 访问服务器。
下面是我的代码：
//Initializing ftp request
ftp ftpClient = new ftp(@"ftp://192.168.xx.xx/", "username", "password");
MessageBox.Show((ftpClient.upload("FILE.TAB", @"C:\FILE.TAB")).ToString());
public ftp(string hostIP, string userName, string password)
{
host = hostIP; user = userName; pass = password;
}
public string upload(string remoteFile, string localFile)
{
try
{
/* Create an FTP Request */
ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + remoteFile);
/* Log in to the FTP Server with the User Name and Password Provided */
ftpRequest.Credentials = new NetworkCredential(user, pass);
///* When in doubt, use these options */
ftpRequest.UseBinary = false;
ftpRequest.UsePassive = true;
ftpRequest.KeepAlive = true;
/* Specify the Type of FTP Request */
ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
/* Establish Return Communication with the FTP Server */
ftpResponse = (FtpWebResponse)ftpRequest.GetResponse();
ftpStream = ftpRequest.GetRequestStream();
/* Open a File Stream to Read the File for Upload */
FileStream localFileStream = new FileStream(localFile, FileMode.Open);
/* Buffer for the Downloaded Data */
byte[] byteBuffer = new byte[bufferSize];
int bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
/* Upload the File by Sending the Buffered Data Until the Transfer is Complete */
while (bytesSent != 0)
{
ftpStream.Write(byteBuffer, 0, bytesSent);
bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
}
/* Resource Cleanup */
localFileStream.Close();
ftpStream.Close();
ftpRequest = null;
return "0";
}
catch (Exception ex) { return ex.ToString(); }
//return 1;
}
我在上面的代码中得到的错误是“无效的 URL ....”。
当我尝试在浏览器上运行它时出现错误：
但我可以在 Windows 中使用常用的 cmd 命令进行连接：
有什么建议么？？
