範例

下列程式碼範例會顯示上次修改 FTP 伺服器上檔案的日期和時間。

static bool GetDateTimestampOnServer( Uri^ serverUri )
{
   // The serverUri should start with the ftp:// scheme.
   if ( serverUri->Scheme != Uri::UriSchemeFtp )
   {
      return false;
   }

   // Get the object used to communicate with the server.
   FtpWebRequest^ request = dynamic_cast<FtpWebRequest^>(WebRequest::Create( serverUri ));
   request->Method = WebRequestMethods::Ftp::GetDateTimestamp;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Console::WriteLine( "{0} {1}", serverUri, response->LastModified );

   // The output from this method will vary depening on the 
   // file specified and your regional settings. It is similar to:
   // ftp://contoso.com/Data.txt 4/15/2003 10:46:02 AM
   return true;
}

public static bool GetDateTimestampOnServer (Uri serverUri)
{
    // The serverUri should start with the ftp:// scheme.
    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }

    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create (serverUri);
    request.Method = WebRequestMethods.Ftp.GetDateTimestamp;
    FtpWebResponse response = (FtpWebResponse)request.GetResponse ();
    Console.WriteLine ("{0} {1}",serverUri,response.LastModified);

    // The output from this method will vary depending on the
    // file specified and your regional settings. It is similar to:
    // ftp://contoso.com/Data.txt 4/15/2003 10:46:02 AM
