След анулиране на BackGroundWorker, в DoWork, CancellationPending е true, но когато той стигне до RunWorkerCompleted, CancellationPending е false. Не знам какво направих погрешно?
static BackgroundWorker b1;
static void Main(string[] args)
{
b1=new BackgroundWorker();
b1.DoWork += new DoWorkEventHandler(work1);
b1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(completed);
b1.WorkerSupportsCancellation = true;
b1.RunWorkerAsync("Hellow");
Console.ReadLine();
}
private static void completed(object sender, RunWorkerCompletedEventArgs e)
{
if (((BackgroundWorker)sender).CancellationPending)
Console.WriteLine("Canceled!");
else
Console.WriteLine("Result:" + e.Result);//it goes here every time
}
private static void work1(object sender, DoWorkEventArgs e)
{
((BackgroundWorker)sender).CancelAsync();
if (((BackgroundWorker)sender).CancellationPending)
{
e.Cancel = true;
}
}
Между другото, как мога да добавя грешка, възникнала в DoWork, към RunWorkerCompletedEventArgs.Error, за да я предам на потребителя?
