WaitAll(System.Threading.Tasks.Task[],System.TimeSpan)

Waits for all of the provided cancellable System.Threading.Tasks.Task objects to complete execution within a specified time interval.

Syntax

public static bool WaitAll (Task[] tasks, TimeSpan timeout)

Parameters

tasks
An array of System.Threading.Tasks.Task instances on which to wait.
timeout
A TimeSpan that represents the number of milliseconds to wait, or a TimeSpan that represents -1 milliseconds to wait indefinitely.

Returns

true if all of the System.Threading.Tasks.Task instances completed execution within the allotted time; otherwise, false.

Remarks

The cancellationToken argument is used to cancel the wait operation. If it is canceled, the Wait returns false (False in Visual Basic). Cancellation of the tasks is a distinct operation, and is signaled by the AggregateException as noted above.
