OutputStream

You can upload a file to an FTP server using GetOutputStream method.

[C#]

// create new Ftp instance

Ftp ftp = new Ftp(hostname,username,password,port);                        

// establish connection

ftp.Connect();

// create new System.IO.FileInfo instance

FileInfo fileInfo = new FileInfo( "C:\\FileToUpload.txt" );

// opens the file to upload

Stream inputStream = fileInfo.OpenRead();

// get the OutputStream from the data connection

Stream outputStream = ftp.GetOutputStream( fileInfo.Name, false, 0 );

// an array of bytes

byte[] buffer = new byte[ 8192 ];

// the total number of bytes read into the buffer

int read = 0;

// reads a sequence of bytes from the current file

while( ( read = inputStream.Read( buffer, 0, buffer.Length ) ) != 0 ) {

 // writes a sequence of bytes to the current stream

 outputStream.Write( buffer, 0, read );

}

// closes the current streams

inputStream.Close();

outputStream.Close();

// disconnect

ftp.Disconnect();
