Parametry

transaction
DbTransaction

Transakce.

eventData
TransactionEventData

Kontextové informace o připojení a transakci

result
InterceptionResult

Představuje aktuální výsledek, pokud existuje. Tato hodnota bude nastavena IsSuppressed , true pokud některé předchozí zachytávání potlačí provádění voláním Suppress(). Tato hodnota se obvykle používá jako návratová hodnota pro implementaci této metody.

cancellationToken
CancellationToken

A CancellationToken , která se má sledovat při čekání na dokončení úkolu.

Návraty

ValueTask<InterceptionResult>
Task<InterceptionResult>

Pokud IsSuppressed ano false, ef bude pokračovat jako normální. Pokud IsSuppressed ano true, ef potlačí operaci, kterou se chystá provést. Implementace této metody pro jakýkoli průsečík, který se nepokouší potlačit operaci, je vrátit result hodnotu předanou.

Výjimky

OperationCanceledException

Pokud je zrušena CancellationToken .
