'Declaration
 
Public Function BeginDisconnect( _
   ByVal callback As AsyncCallback, _
   ByVal state As Object _
) As IAsyncResult

'Usage
 
Dim instance As AsyncFtpClient
Dim callback As AsyncCallback
Dim state As Object
Dim value As IAsyncResult
 
value = instance.BeginDisconnect(callback, state)

public IAsyncResult BeginDisconnect( 
   AsyncCallback callback,
   object state
)

Parameters

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 FTP client is in an invalid state, for example, sending a file, the BeginDisconnect method will throw an exception. It is up to the user to call BeginAbort before calling BeginDisconnect.

The BeginDisconnect method will send the QUIT command to the FTP server and make sure that the command connection is closed.

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