How to use FTP events

edtFTPnet/PRO's events are useful for providing feedback on the progress of FTP operations. For example, the BytesTransferred event fires during a file transfer each time another n bytes have been transferred, where n is equal to FTPConnection.TransferNotifyInterval.  An event such as this may be used to provide progress feedback during long transfer operations.

Handling events is done using delegates in the same way as other .NET events.  For example, to handle the Connected event, an event handler must be defined:

privatevoid ftpConnection_Connected(object sender, EnterpriseDT.Net.Ftp.FTPConnectionEventArgs e)
{
	Print("Connected to "; + e.ServerAddress + ":" + e.ServerPort);
}

A delegate for this event-handler must then be added to the event:

ftpConnection.Connected += new FTPConnectionEventHandler(ftpConnection_Connected);

Once this has been done, the ftpConnection_Connect method will be called when a connection with the server has been established.

The following events relate to specific FTP operations. Most events are available in FTPConnection, however certain security-related events are only available in SecureFTPConnection:

The following events are of a more general nature and can occur across a range of FTP operations:

The Error event is of particular importance when using asynchronous processing since it is called if an exception is thrown occurs during an FTP operation.  The topic How to use asynchronous methods has information about using events with asynchronous methods.
