BackgroundWorker的應用，backgroundworker

BackgroundWorker 可以用於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);
            }
        }
