| WaitAsync(CancellationToken) |
Gets a Task that will complete when this Task completes or when the specified CancellationToken has cancellation requested. |
| WaitAsync(TimeSpan) |
Gets a Task that will complete when this Task completes or when the specified timeout expires. |
| WaitAsync(TimeSpan, CancellationToken) |
Gets a Task that will complete when this Task completes, when the specified timeout expires, or when the specified CancellationToken has cancellation requested. |
| WaitAsync(TimeSpan, TimeProvider) |
Gets a Task that will complete when this Task completes or when the specified timeout expires. |
| WaitAsync(TimeSpan, TimeProvider, CancellationToken) |
Gets a Task that will complete when this Task completes, when the specified timeout expires, or when the specified CancellationToken has cancellation requested. |

System::Threading::Tasks::Task ^ WaitAsync(System::Threading::CancellationToken cancellationToken);public System.Threading.Tasks.Task WaitAsync(System.Threading.CancellationToken cancellationToken);member this.WaitAsync : System.Threading.CancellationToken -> System.Threading.Tasks.TaskPublic Function WaitAsync (cancellationToken As CancellationToken) As TaskParameters
- cancellationToken
- CancellationToken
The CancellationToken to monitor for a cancellation request.
Returns
The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.
Exceptions
The cancellation token was canceled. This exception is stored into the returned task.
Remarks
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by Wait().
