Flush Method

public FtpResponse Flush(
   int timeout
)

Public Function Flush( _
   ByVal timeout As Integer _
) As FtpResponse

public:
  FtpResponse Flush(
   int timeout
);

Parameters

timeout

The length of time (in milliseconds) to wait for data to be received.

Return Value

Remarks

This method can either be used to read messages from the FTP server that are not responses to any commands, or to set the State property back to the Ready state if it is not Ready state after aborting a file transfer with the Cancel method.

If the State of the Ftp object is Reading, Sending or Processing and no data is available within the specified time limit, it returns with a null reference. If data is available, it is read and returned. If the object is in any other state, an exception is thrown.

Shows how to use the Flush method to read and return control connection data, if available.
