 Stream stream = new MemoryStream();

//get image

 stream = http://ftp.GetDownloadStream(files[i].Name);

 

then try to use this 

 string d= http://ftp.GetCurrentFolder();

it was throw exception 

Cannot perform the requested operation because the FTP client is already processing a command.

Hi Omar,

 

Most likely, you didn’t close the stream object before calling GetCurrentFolder().

GetDownloadStream() issues a “receive file” command to the server and lets you control the download stream. The FTP client remains in a “ReceivingFile” state until the stream is closed.

You could change your code to the following:

Stream destinationStream = new MemoryStream();

// Get a download stream for the current file
using( Stream stream = http://ftp.GetDownloadStream( files[i].Name ) )
{
  byte[] buffer = new byte[ 32 * 1024 ];
  int read;

  // While there is data to download
  while( ( read = stream.Read( buffer, 0, buffer.Length ) ) > 0 )
  {
    // Write the downloaded data to our destination stream
    destinationStream.Write( buffer, 0, read );
  }
}

// Get the current folder

string d = http://ftp.GetCurrentFolder();
