BackgroundWorker的應用

BackgroundWorker 可以用于對控制進度條的進度，先new一個

BackgroundWorker bWork = new BackgroundWorker();

bWork.WorkerSupportsCancellation = true;//設置能夠取消 bWork.WorkerReportsPRogress = true;//是否報告進度

接下來就是2個事件，dowork 執(zhí)行操作，

//接受進展，設置進度條void bWork_ProgressChanged(object sender, ProgressChangedEventArgs e)        {            this.progressBar1.Value = e.ProgressPercentage;        }        void bWork_DoWork(object sender, DoWorkEventArgs e)        {            int i = 0;            while (i <= 100)            {                if (bWork.CancellationPending)                {                    e.Cancel = true;                    break;                }                bWork.ReportProgress(i++);//報告進展                Thread.Sleep(100);            }        }
