ftp技术多线程上传图片
我现在想做一个winfrom ,想利用ftp技术进行多线程的上传图片，而且还有进度条显示！请哪个大侠能指点一下，给个例子，谢谢!

[解决办法]
只要开一个上传的线程就行了，只要不卡住UI就可以了

类似这样的代码
Thread t = new Thread(workThreadFunc);
t.Start();

backgroundwork
[解决办法]

C# code

bw = new BackgroundWorker();                                            bw.WorkerReportsProgress = true;                                            bw.DoWork += new DoWorkEventHandler(bw_DoWork);                                            bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);                                            bw.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);                                            bw.RunWorkerAsync(temp);private void bw_DoWork(object sender, DoWorkEventArgs e)        {            ftp 下载        }
[解决办法]
比如用webclient

C# code
        WebClient wc = new WebClient();        byte[] data = new byte[10];        wc.UploadDataCompleted += new UploadDataCompletedEventHandler(wc_UploadDataCompleted);        wc.UploadDataAsync(new Uri("http://www.sina.com.cn"), data);
