The file mask of the remote files to retrieve. This parameter can include a filtering mask to limit the files that are retrieved. For example, if System.String.Empty is specified, the entire contents of the current working folder will be retrieved. If "*.txt" is used, all the files in the current working folder that have the TXT extension will be retrieved. Some FTP servers may be case-sensitive!
Callback method to be called when the asynchronous operation is completed.
An object containing state information for this operation.
'Usage
Dim instance As AsyncFtpClient
Dim remoteFileMask As String
Dim callback As AsyncCallback
Dim state As Object
Dim value As IAsyncResult
value = instance.BeginGetFolderContents(remoteFileMask, callback, state)
The file mask of the remote files to retrieve. This parameter can include a filtering mask to limit the files that are retrieved. For example, if System.String.Empty is specified, the entire contents of the current working folder will be retrieved. If "*.txt" is used, all the files in the current working folder that have the TXT extension will be retrieved. Some FTP servers may be case-sensitive!
callback
Callback method to be called when the asynchronous operation is completed.
state
An object containing state information for this operation.
Return Value
An System.IAsyncResult representing the status of the asynchronous operation.
Remarks
If you want to retrieve the contents of another folder, 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. Absolute paths can also be provided, however some FTP servers might not support absolute paths and different server types may have different ways of representing absolute paths.
The current working folder can be retrieved via the BeginGetCurrentFolder%M:Xceed.Ftp.AsyncFtpClient.EndGetCurrentFolder(System.IAsyncResult)% methods.
The TYPE command will be sent regardless of the value of the FtpClient.SendTypeCommand property when calling the BeginGetFolderContents method.
When using a callback, the System.IAsyncResult is provided as a parameter. You should call EndGetFolderContents in that callback. When NOT providing a callback, you should keep the returned IAsyncResult and call EndGetFolderContents with it when ready to complete. In this later case, the call to EndGetFolderContents may block until the operation completes.
