WinSCP：上传/下载文件时查看进度

Question

I use the WinSCP .NET Library to upload/download files from a SFTP server by using PutFiles(..) and GetFiles(..) .

Is there a way to see the progress while uploading/downloading files of this server? So for example, to get the percentage of the file-size, which is already downloaded.

Thanks, Michael

There's a FileTransferProgress event on the Session class of the WinSCP library .

You just have to register for that event and then update your UI from within that handler:

using (Session session = new Session())
{
    // Will continuously report progress of transfer
    session.FileTransferProgress += SessionFileTransferProgress;

    /* Down / upload code here */
}

void SessionFileTransferProgress(object sender, FileTransferProgressEventArgs e)
{
    // Print transfer progress
    Console.Write("\r{0} ({1:P0})", e.FileName, e.FileProgress);
}

Please note that FileTransferProgressEventArgs.Side enables you to tell if the event args are for an upload or a download. Other properties contain information about speed of transfer, the file currently transferred etc...

Here's the complete doc for it: http://winscp.net/eng/docs/library_session_filetransferprogress

Edit: the event is called at the beginning of each new transfer (file) and then at most once a second for each transfer.
