IAsyncEnumerable의 동작 취소는 좀 다른 방법을 사용합니다.
public static async Task IndefinitelyRunningWrappedMethodCancelled()
{
var cancellationTokenSource = new CancellationTokenSource();
cancellationTokenSource.CancelAfter(7000);
var indefinitelyRunningRange = GetIndefinitelyRunningRangeWrapperAsync();
await foreach (int index in indefinitelyRunningRange.WithCancellation(cancellationTokenSource.Token))
{
// Do something with the index
}
}
private static async IAsyncEnumerable<int> GetIndefinitelyRunningRangeAsync(
[EnumeratorCancellation] System.Threading.CancellationToken cancellationToken = default)
{
int index = 0;
while (true)
{
await Task.Delay(5000, cancellationToken);
yield return index++;
}
}
