public void ReceiveFile( 
   string remoteFilename,
   long offset,
   string localFilename,
   bool append
)

Parameters

remoteFilename

The filename of the file to retrieve. Some FTP servers may be case-sensitive!

offset

The byte offset (of the remote file) at which to start receiving data from the remote file. If append is true, the remote file will be appended to the end of the local file no matter what the value of offset. Therefore, to implement a real resume procedure, the size of the local file must be specified in offset and append must be set to true.

localFilename

The path and filename of the file as it will be stored on the local system.

append

true if the file should append itself to the local file if it already exists; false if the local file should be overwritten.

By default, the file will be received from the current working folder. If you want to receive the file from another location, you could use the ChangeCurrentFolder and/or ChangeToParentFolder methods to change the current working folder. Absolute paths can also be provided, however some FTP servers might not support absolute paths and different server types may have different ways of representing absolute paths.

The current working folder can be retrieved via the GetCurrentFolder method.

The ReceiveFile method will send the RETR, REST and PORT or PASV commands and optionally the TYPE command to the FTP server.
