Dim value As IAsyncResult

   AuthenticationMethod authenticationMethod,
   VerificationFlags verificationFlags,
   Certificate clientCertificate,
   AsyncCallback callback,
   object state
)

Parameters

hostName

The hostname of the FTP server to connect to. An IP address can also be used.

port

The port of the FTP server to which to connect to. If 0 is specified for the port, 21 will be used.

authenticationMethod

The authentication method used to connect to the FTP server.

verificationFlags

The verification flags used to verify the FTP server's certificate.

clientCertificate

The FTP client's certificate.

callback

Callback method to be called when the asynchronous operation is completed.

state

An object containing state information for this operation.

Return Value

If the IP address contains a port (ie.: 192.168.0.42:2121) then the FTP client will connect on the specified port rather than port 21 (default).

This method will only connect you to the FTP server. Once connected, you must call the BeginLogin%M:Xceed.Ftp.AsyncFtpClient.EndLogin(System.IAsyncResult)% methods to log-in to the FTP server.

When using a callback, the System.IAsyncResult is provided as a parameter. You should call EndConnect in that callback. When NOT providing a callback, you should keep the returned IAsyncResult and call EndConnect with it when ready to complete. In this later case, the call to EndConnect may block until the operation completes.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
