BackgroundWorker的应用

BackgroundWorker 可以用于对控制进度条的进度，先new一个

BackgroundWorker bWork = new BackgroundWorker();

bWork.WorkerSupportsCancellation = true;//设置能够取消 bWork.WorkerReportsPRogress = true;//是否报告进度

接下来就是2个事件，dowork 执行操作，

//接受进展，设置进度条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++);//报告进展                Thread.Sleep(100);            }        }
