WaitAsync(TimeSpan, TimeProvider)

Source:

Task.cs

Gets a Task that will complete when this Task completes or when the specified timeout expires.

public:
 System::Threading::Tasks::Task ^ WaitAsync(TimeSpan timeout, TimeProvider ^ timeProvider);

public System.Threading.Tasks.Task WaitAsync (TimeSpan timeout, TimeProvider timeProvider);

member this.WaitAsync : TimeSpan * TimeProvider -> System.Threading.Tasks.Task

Public Function WaitAsync (timeout As TimeSpan, timeProvider As TimeProvider) As Task

Parameters

timeout

TimeSpan

The timeout after which the Task should be faulted with a TimeoutException if it hasn't otherwise completed.

timeProvider

TimeProvider

The TimeProvider with which to interpret timeout.

Returns

Task

The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.

Exceptions

ArgumentNullException

The timeProvider argument is null.

WaitAsync(TimeSpan, TimeProvider, CancellationToken)

Source:

Task.cs

Gets a Task that will complete when this Task completes, when the specified timeout expires, or when the specified CancellationToken has cancellation requested.

public:
 System::Threading::Tasks::Task ^ WaitAsync(TimeSpan timeout, TimeProvider ^ timeProvider, System::Threading::CancellationToken cancellationToken);

public System.Threading.Tasks.Task WaitAsync (TimeSpan timeout, TimeProvider timeProvider, System.Threading.CancellationToken cancellationToken);

member this.WaitAsync : TimeSpan * TimeProvider * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Function WaitAsync (timeout As TimeSpan, timeProvider As TimeProvider, cancellationToken As CancellationToken) As Task

Parameters

timeout

TimeSpan

The timeout after which the Task should be faulted with a TimeoutException if it hasn't otherwise completed.

timeProvider

TimeProvider

The TimeProvider with which to interpret timeout.

cancellationToken

CancellationToken

The CancellationToken to monitor for a cancellation request.

Returns

Task

The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.

Exceptions

ArgumentNullException

The timeProvider argument is null.

OperationCanceledException

The cancellation token was canceled. This exception is stored into the returned task.

WaitAsync(TimeSpan, CancellationToken)

Source:

Task.cs

Gets a Task that will complete when this Task completes, when the specified timeout expires, or when the specified CancellationToken has cancellation requested.

public:
 System::Threading::Tasks::Task ^ WaitAsync(TimeSpan timeout, System::Threading::CancellationToken cancellationToken);

public System.Threading.Tasks.Task WaitAsync (TimeSpan timeout, System.Threading.CancellationToken cancellationToken);

member this.WaitAsync : TimeSpan * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Function WaitAsync (timeout As TimeSpan, cancellationToken As CancellationToken) As Task

Parameters

timeout

TimeSpan

The timeout after which the Task should be faulted with a TimeoutException if it hasn't otherwise completed.

cancellationToken

CancellationToken

The CancellationToken to monitor for a cancellation request.

Returns

Task

The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.

Exceptions

OperationCanceledException

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(TimeSpan).

WaitAsync(TimeSpan)

Source:

Task.cs

Gets a Task that will complete when this Task completes or when the specified timeout expires.

public:
 System::Threading::Tasks::Task ^ WaitAsync(TimeSpan timeout);

public System.Threading.Tasks.Task WaitAsync (TimeSpan timeout);

member this.WaitAsync : TimeSpan -> System.Threading.Tasks.Task

Public Function WaitAsync (timeout As TimeSpan) As Task

Parameters

timeout

TimeSpan

The timeout after which the Task should be faulted with a TimeoutException if it hasn't otherwise completed.

Returns

Task

The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.

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.

WaitAsync(CancellationToken)

Source:

Task.cs

Gets a Task that will complete when this Task completes or when the specified CancellationToken has cancellation requested.

public:
 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.Task

Public Function WaitAsync (cancellationToken As CancellationToken) As Task

Parameters

cancellationToken

CancellationToken

The CancellationToken to monitor for a cancellation request.

Returns

Task

The Task representing the asynchronous wait. It may or may not be the same instance as the current instance.

Exceptions

OperationCanceledException

The cancellation token was canceled. This exception is stored into the returned task.

Remarks
