using System.Threading.Tasks;
public class Example
{
public static void Main()
{
CancellationTokenSource source = new CancellationTokenSource();
var t = Task.Run(async delegate
{
await Task.Delay(TimeSpan.FromSeconds(1.5), source.Token);
return 42;
});
source.Cancel();
try {
t.Wait();
}
catch (AggregateException ae) {
foreach (var e in ae.InnerExceptions)
Console.WriteLine("{0}: {1}", e.GetType().Name, e.Message);
}
Console.Write("Task t Status: {0}", t.Status);
if (t.Status == TaskStatus.RanToCompletion)
Console.Write(", Result: {0}", t.Result);
source.Dispose();
}
}输出：
TaskCanceledException: A task was canceled. Task t Status: Canceled
