class Task

in global :: System . Threading . Tasks

Represents an asynchronous operation.

public object AsyncState { get; }

Gets the state object supplied when the was created, or null if none was supplied.

  • Returns An that represents the state data that was passed in to the task when it was created.

public static Task CompletedTask { get; }

Gets a task that has already completed successfully.

  • Returns The successfully completed task.

public static Nullable<int> CurrentId { get; }

Returns the ID of the currently executing .

  • Returns An integer that was assigned by the system to the currently-executing task.

public static Task Delay( int millisecondsDelay )

Creates a task that completes after a specified number of milliseconds.

  • millisecondsDelay The number of milliseconds to wait before completing the returned task, or -1 to wait indefinitely.
  • Returns A task that represents the time delay.

public static Task Delay( int millisecondsDelay, CancellationToken cancellationToken )

Creates a cancellable task that completes after a specified number of milliseconds.

  • millisecondsDelay The number of milliseconds to wait before completing the returned task, or -1 to wait indefinitely.
  • cancellationToken A cancellation token to observe while waiting for the task to complete.
  • Returns A task that represents the time delay.

public static Task Delay( TimeSpan delay )

Creates a task that completes after a specified time interval.

  • delay The time span to wait before completing the returned task, or to wait indefinitely.
  • Returns A task that represents the time delay.

public static Task Delay( TimeSpan delay, CancellationToken cancellationToken )

Creates a cancellable task that completes after a specified time interval.

  • delay The time span to wait before completing the returned task, or to wait indefinitely.
  • cancellationToken A cancellation token to observe while waiting for the task to complete.
  • Returns A task that represents the time delay.

public AggregateException Exception { get; }

Gets the that caused the to end prematurely. If the completed successfully or has not yet thrown any exceptions, this will return .

  • Returns The that caused the to end prematurely.

public static Task<TResult> FromCanceled( CancellationToken cancellationToken )

Creates a that's completed due to cancellation with a specified cancellation token.

  • cancellationToken The cancellation token with which to complete the task.
  • Returns The canceled task.

public static Task FromCanceled( CancellationToken cancellationToken )

Creates a that's completed due to cancellation with a specified cancellation token.

  • cancellationToken The cancellation token with which to complete the task.
  • Returns The canceled task.

public static Task<TResult> FromException( Exception exception )

Creates a that has completed with a specified exception.

  • exception The exception with which to complete the task.
  • Returns The faulted task.

public static Task FromException( Exception exception )

Creates a that has completed with a specified exception.

  • exception The exception with which to complete the task.
  • Returns The faulted task.

public int Id { get; }

Gets an ID for this instance.

  • Returns The identifier that is assigned by the system to this instance.

public bool IsCanceled { get; }

Gets whether this instance has completed execution due to being canceled.

  • Returns if the task has completed due to being canceled; otherwise .

public bool IsCompleted { get; }

Gets a value that indicates whether the task has completed.

  • Returns if the task has completed (that is, the task is in one of the three final states: , , or ); otherwise, .

public bool IsCompletedSuccessfully { get; }

No summary.

public bool IsFaulted { get; }

Gets whether the completed due to an unhandled exception.

  • Returns if the task has thrown an unhandled exception; otherwise .

public TaskStatus Status { get; }

Gets the of this task.

  • Returns The current of this task instance.
