Syntax

public class AsyncAutoResetEvent : QueuedSynchronizer, IAsyncResetEvent, IAsyncEvent, IDisposable, IResettable

Constructors

AsyncAutoResetEvent(bool)

Initializes a new asynchronous reset event in the specified state.

Declaration

public AsyncAutoResetEvent(bool initialState)

Parameters

Type	Name	Description
bool	initialState	true to set the initial state signaled; false to set the initial state to non signaled.

AsyncAutoResetEvent(bool, int)

Initializes a new asynchronous reset event in the specified state.

Declaration

public AsyncAutoResetEvent(bool initialState, int concurrencyLevel)

Parameters

Type	Name	Description
bool	initialState	true to set the initial state signaled; false to set the initial state to non signaled.
int	concurrencyLevel	The expected number of concurrent flows.

Exceptions

Type	Condition
ArgumentOutOfRangeException	concurrencyLevel is less than or equal to zero.

Properties

IsSet

Indicates whether this event is set.

Declaration

public bool IsSet { get; }

Property Value

Type	Description
bool

Methods

Reset()

Sets the state of this event to non signaled, causing consumers to wait asynchronously.

Declaration

public bool Reset()

Returns

Type	Description
bool	true if the operation succeeds; otherwise, false.

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.

Set()

Sets the state of the event to signaled, resuming the suspended caller.

Declaration

public bool Set()

Returns

Type	Description
bool	true if the operation succeeds; otherwise, false.

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.

Wait(TimeSpan)

Blocks the current thread until this event is set.

Declaration

public bool Wait(TimeSpan timeout)

Parameters

Type	Name	Description
TimeSpan	timeout	The time to wait for the event.

Returns

Type	Description
bool	true, if this event was set; otherwise, false.

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.
ArgumentOutOfRangeException	timeout is negative.

WaitAsync(CancellationToken)

Turns caller into idle state until the current event is set.

Declaration

public ValueTask WaitAsync(CancellationToken token = default)

Parameters

Type	Name	Description
CancellationToken	token	The token that can be used to abort wait process.

Returns

Type	Description
ValueTask	The task representing asynchronous result.

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.
OperationCanceledException	The operation has been canceled.

WaitAsync(TimeSpan, CancellationToken)

Turns caller into idle state until the current event is set.

Declaration

public ValueTask<bool> WaitAsync(TimeSpan timeout, CancellationToken token = default)

Parameters

Type	Name	Description
TimeSpan	timeout	The interval to wait for the signaled state.
CancellationToken	token	The token that can be used to abort wait process.

Returns

Type	Description
ValueTask<bool>	true if signaled state was set; otherwise, false.

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.
ArgumentOutOfRangeException	timeout is negative.
OperationCanceledException	The operation has been canceled.
