BackgroundWorker.WorkerSupportsCancellation Property

Set the WorkerSupportsCancellation property to true if you want the BackgroundWorker to support cancellation. When this property is true, you can call the CancelAsync method to interrupt a background operation.

When this property is false, calling the CancelAsync method will cause an InvalidOperationException.

The following code example demonstrates the use of the WorkerSupportsCancellation property to check whether a background operation allows cancellation before canceling it. To view the complete code for this sample, see How to: Use a Background Worker.

private void buttonCancel_Click(object sender, RoutedEventArgs e)
{
    if (bw.WorkerSupportsCancellation == true)
    {
        bw.CancelAsync();
    }
}
