AsyncManualResetEvent(bool, int)

Initializes a new asynchronous reset event in the specified state.

Declaration

public AsyncManualResetEvent(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 potential number of suspended callers.

Exceptions

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

IsSet

Indicates whether this event is set.

Declaration

public bool IsSet { get; }

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, allowing one or more awaiters to proceed.

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.

Set(bool)

Sets the state of the event to signaled, allowing one or more awaiters to proceed; and, optionally, reverts the state of the event to initial state.

Declaration

public bool Set(bool autoReset)

Parameters

Type	Name	Description
bool	autoReset	true to reset this object to non-signaled state automatically; false to leave this object in signaled state.

Returns

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

Exceptions

Type	Condition
ObjectDisposedException	The current instance has already been disposed.

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

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.
