A that contains the event data. Raises the event. A that contains the event data. Raises the event. A that contains the event data. Initializes a new instance of the Ftp class. Disposes the object and all the socket objects. Calling this method ensures that all resources are freed. It is not necessary to call this method if the FTP session is successfully closed using Disconnect method. Releases the unmanaged resources used by the and optionally releases the managed resources. true to release both managed and unmanaged resources; false to release only unmanaged resources. Finalizer. Called by garbage collector during object destruction. Aborts the current operation.

The operation need not end immediately, it will finish within the interval specified by AbortTimeout. Aborting data transfering operations (including , and ) may take twice the amount of time specified by .

The aborted operation will end either successfully, or with of status OperationAborted or Timeout. The object may remain in Reading, Sending or Processing state. In this case, call to get back to the Ready state.

Retrieves the raw list of files and directories as received from the server. Arguments for the list command. The listing command to use. The array of response lines.

This method supports retrieving the raw listings using either the LIST command or MLSD command. Using GetList is a better choice in most cases, because it returns the parsed list, unlike .

Please note that requesting a FtpListingType.MachineProcessingList list will only work on servers that support this extension - this can be determined using the property.

Caution: The meaning of the arguments argument is not defined by RFC and varies from server to server. Some servers interpret it as parameters to dir command, some as a filename, some ignore it and some report an error. Calling this method with arguments other than null is not recommended and will make your code incompatible with many FTP servers.

Returns parsed list of files and directories. Arguments for the LIST or MLSD command. An instance of containing the file list.

This method will use the MLSD command if the server supports it and it is enabled (see and properties). It will use the LIST command if MLSD is not supported or disabled.

Reads and returns any control connection data that might have remained unread after an asynchronouos operation aborted by a call to Abort method.

It can also be used to read FTP server messages that are not responses to any commands.

If the state of the object is Ready and no data is available, this method returns immediately with a null reference. 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.

RFC 959 and RFC 1123 recommend sending IP and Synch signals before the ABOR command. Many FTP servers even ignore an ABOR command without the preceeding IP and Synch signals. The default behaviour of Rebex FTP for .NET is to send IP and Synch, unless a proxy is in use.

However, there are some bad FTP servers that react in an inappropriate way to IP and Synch signals. Problems with some network setups were also experienced.

Setting this flag will disable sending of IP and Synch signals even through non-proxied FTP sessions. You might want to try disabling it if you experience problems while aborting data transfers.

Do not send the ABOR command when aborting download.

This flag will cause the component not to send ABOR command while aborting a download. The download will be aborted by closing the receiving socket.

Caution: Only use this if you know what you are doing and why you need this. Please note that some servers might react by closing the control connection.

Send NOOP command during file transfers every 10 minutes. This is only needed if the FTP control connection is otherwise being dropped by a buggy router or firewall while a very long data transfer is in progress. Forces the method to do immediate unprotect, without exchange of CloseNotify alert messages. This is in violation of both FTPS and TLS RFCs, but some servers still require this to be set. However, be very careful when using this options, because the might not work with well-behaved servers when this is set. Please note that silent CCC is always used when GlobalSCAPE, IpSwitch WS_FTP or Enterprise UNIX 2.2.00 servers are detected and this option has no effect on any of these three servers.

The method returns a stream to use to send data for the . Once the instance has been returned, you can send data with the by using the method.

Note: Unlike , you do not have to set the value of the property before writing data to the stream. is ignored.

CAUTION: You must call the method to close the stream and release the connection for reuse. Failure to close the stream will cause it to remain open and your application may run out of connections.

 Begins an asynchronous request for a instance to use to write data. An optional asynchronous callback to be called when the operation is complete. A user-provided object that identifies this particular asynchronous operation. An that references the asynchronous operation. Ends a pending asynchronous request for a instance. Stores state information for this asynchronous operation as well as any user defined data. If successful, returns the . Returns instance to use to write data. A containing the response. The actual instance returned is an instance of , and can be typecast to that class. Occurs when a response is received from the server. Occurs when a command is send to the server. Occurs when the state of the object is changed. Occurs when data is send or received. Gets or sets the debug level that specifies an amount of messages event handlers receive. Debug level. Gets or sets TLS/SSL security parameters. Security parameters. Gets or sets the connection security. Occurs when a TLS/SSL event is processed. Gets the instance of IWebRequestCreate for registering with WebRequest.Create. The instance of IWebRequestCreate Gets or sets the Content-length HTTP header. Not supported. Not supported by . Gets or sets the value of the Content-type HTTP header. The value of the Content-type HTTP header. Not used by . Gets or sets the credentials to submit to the proxy server for authentication. An containing the credentials to submit to the proxy server for authentication. Only credentials of type are supported by . Gets or sets proxy information for the request. The instance to use to proxy the request.

The Proxy property identifies the instance to use to process requests to Internet resources. To specify that no proxy should be used, set the Proxy property to the proxy instance returned by the method.

If this property is not set to an instance of , it is ignored.

Gets or sets a collection of the name/value pairs that make up the HTTP headers. A containing the name/value pairs that make up the headers for the HTTP request. Not used by . Gets or sets the method for the request. The method for the request.

The Method property can be set to either RETR or STOR command. PUT and GET are also supported for compatibility with HttpWebRequest.

Changing the Method property after the request has been started by calling , , , or method will throw an .

 Gets or sets a value indicating whether to send a preauthentication header with the request. true to send a WWW-authenticate HTTP header with the initial request; otherwise, false. The default is false. Not used by . Gets the URI of the request. A containing the URI of the Internet resource passed to the method. Gets or sets the time-out value for a request.

The length of time, in milliseconds, until the request times out, or the value of -1 or 0 to indicate that the request does not time out. Default is -1.

Timeout is the number of milliseconds that a synchronous request made with the method waits for a response, and the methods waits for a stream. If a resource does not respond within the time-out period, the request throws a with the Status property set to Timeout.

The Timeout property has no effect on asynchronous requests made with the or methods.

Minimal value is 1000. Setting this to a value lower than 1000 will set it to 1000.

Provides an FTP-specific implementation of the class. The class contains support for the properties and methods included in . Gets the used to read the body of the response from the server. A user to read the body of the response.

CAUTION: You must call either the or the FtpWebResponse.Close method to close the stream and release the connection for reuse. It is not necessary to call both Stream.Close and FtpWebResponse.Close, but doing so does not cause an error. Failure to close the stream will cause it to remain open and your application may run out of connections.

 Closes the response stream.

The Close method closes the response stream and releases the connection to the FTP server for reuse by other requests

CAUTION: You must call either the or the FtpWebResponse.Close method to close the stream and release the connection for reuse. It is not necessary to call both Stream.Close and FtpWebResponse.Close, but doing so does not cause an error. Failure to close the stream will cause it to remain open and your application may run out of connections.

 Gets the length of the content returned by the request. The number of bytes returned by the request. Not supported by . Gets the content type of the response. A content type of the response. always returns "binary/octet-stream". Gets the headers associated with this response from the server. A containing the header information returned with the response. always returns an empty collection. Gets the URI of the request. A URI of the request. Encapsulation of FTP stream.
