Parametreler

transaction: DbTransaction

İşlem.

eventData: TransactionEventData

Bağlantı ve işlem hakkında bağlamsal bilgiler.

result: InterceptionResult

Varsa geçerli sonucu temsil eder. Önceki bir kesme noktası tarafından çağrılarak trueSuppress()yürütme engellendiyse bu değer IsSuppressed olarak ayarlanır. Bu değer genellikle bu yöntemin uygulanması için dönüş değeri olarak kullanılır.

cancellationToken: CancellationToken

CancellationToken Görevin tamamlanmasını beklerken gözlemlemek için bir.

Döndürülenler

Task<InterceptionResult>

ValueTask<InterceptionResult>

ise IsSuppressedfalseEF normal şekilde devam eder. ise IsSuppressedtrueEF, gerçekleştirmek üzere olduğu işlemi bastırır. İşlemi engellemeye çalışmayan herhangi bir kesme noktası için bu yöntemin uygulanması, geçirilen değeri döndürmektir result .

Özel durumlar

OperationCanceledException

CancellationToken İptal edildiyse.
