示例1: downloadButton_Click
private void downloadButton_Click(object sender, EventArgs e)
{
// Start the download operation in the background.
this.backgroundWorker1.RunWorkerAsync();
// Disable the button for the duration of the download.
this.downloadButton.Enabled = false;
// Once you have started the background thread you
// can exit the handler and the application will
// wait until the RunWorkerCompleted event is raised.
// Or if you want to do something else in the main thread,
// such as update a progress bar, you can do so in a loop
// while checking IsBusy to see if the background task is
// still running.
while (this.backgroundWorker1.IsBusy)
{
progressBar1.Increment(1);
// Keep UI messages moving, so the form remains
// responsive during the asynchronous operation.
Application.DoEvents();
}
