BackgroundWorker类的案例
作者:互联网
public partial class MainWindow : Window { BackgroundWorker bgWorker = new BackgroundWorker(); public MainWindow() { InitializeComponent(); //设置属性 bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true;//链接BackgroundWorker的事件处理程序。 bgWorker.DoWork += DoWork_Handle; bgWorker.ProgressChanged += ProgressChanged_Handle; bgWorker.RunWorkerCompleted += RunWorkerCompleted_Handle; } private void btnProcess_Click(object sender, RoutedEventArgs e) { if (!bgWorker.IsBusy) { bgWorker.RunWorkerAsync(); } } private void btnCancel_Click(object sender, RoutedEventArgs e) { bgWorker.CancelAsync(); } private void DoWork_Handle(object sender,DoWorkEventArgs args) { BackgroundWorker worker = sender as BackgroundWorker;//显示的转换给定类型。 for (int i = 0; i <=10; i++) { if (worker.CancellationPending) { args.Cancel = true; break; } else { worker.ReportProgress(i * 10); Thread.Sleep(500); } } } private void ProgressChanged_Handle(object sender, ProgressChangedEventArgs args) { progressBar.Value = args.ProgressPercentage; } private void RunWorkerCompleted_Handle(object sender,RunWorkerCompletedEventArgs args) { progressBar.Value = 0; if (args.Cancelled) { MessageBox.Show("Process was Canceled", "Process Cancelled"); } else { MessageBox.Show("Process was Completed", "Process Completed"); } } }
