KeyedSignalTKey, TResultWait Method

public (TResult , Exception ex) Wait(
	TKey key,
	CancellationToken cancellationToken = default
)

Public Function Wait ( 
	key As TKey,
	Optional cancellationToken As CancellationToken = Nothing
) As ( As TResult, ex As Exception)

public:
ValueTuple<TResult, Exception^> Wait(
	TKey key, 
	CancellationToken cancellationToken = CancellationToken()
)

function Wait(key, cancellationToken);

Parameters

key  TKey

Key to wait on.

cancellationToken  CancellationToken  (Optional)

Optional token to cancel or timeout the wait.

Return Value

• result is the signaled result when successful; otherwise default.
• ex is null on success; otherwise the exception that caused the failure, including OperationCanceledException when canceled.

A failure triggered by Fail(TKey, Exception) returns (default, ex) where ex is the exception provided to Fail(TKey, Exception).Cancellation is treated like a failure where returned ex is an OperationCanceledException.

For asynchronous waiting, use WaitAsync(TKey, CancellationToken).
