'Declaration
 
Public Overloads Function BeginSendFileToUniqueName( _
   ByVal source As Stream, _
   ByVal callback As AsyncCallback, _
   ByVal state As Object _
) As IAsyncResult

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

Parameters

source

A System.IO.Stream whose data is to be sent to the FTP server.

callback

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

state

An object containing state information for this operation.

Return Value

The file will be sent to the current working folder. If you want to send the file to another location, you could use the BeginChangeCurrentFolder%M:Xceed.Ftp.AsyncFtpClient.EndChangeCurrentFolder(System.IAsyncResult)% methods and/or BeginChangeToParentFolder%M:Xceed.Ftp.AsyncFtpClient.EndChangeToParentFolder(System.IAsyncResult)% methods to change the current working folder.

The current working folder can be retrieved via the BeginGetCurrentFolder%M:Xceed.Ftp.AsyncFtpClient.EndGetCurrentFolder(System.IAsyncResult)% methods.

When using this overload of the BeginSendFileToUniqueName method, in the FtpClient.SendingFile event, the TransferringFileEventArgs.LocalFilename property will be System.String.Empty. This overload will also ignore the value of the FtpClient.PreAllocateStorage property.

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