            for (int i = 0; i <= inStream.Length; i++)
            {

                worker.ReportProgress(i);

                //System.Threading.Thread.Sleep(100);

                fileStream.SetLength(inStream.Length);
                int bytesRead = -1;
                byte[] bytes = new byte[bufferSize];

                while (puase);

                if (cancel)
                {
                    offsetw = 0; fileStream.Flush();
                    return;

                }
                bytesRead = inStream.Read(bytes, offsetw, bufferSize);

                fileStream.Write(bytes, offsetw, bytesRead);
                offsetw *= 1024;

            }

内部空while循环，暂停操作，可以在Pause Button中切换puase值
