Dipanggil segera setelah EF memanggil BeginTransactionAsync(IsolationLevel, CancellationToken).

Parameter

connection: DbConnection

Koneksi.

eventData: TransactionEndEventData

Informasi kontekstual tentang koneksi dan transaksi.

result: DbTransaction

Hasil panggilan ke BeginTransactionAsync(IsolationLevel, CancellationToken). Nilai ini biasanya digunakan sebagai nilai pengembalian untuk implementasi metode ini.

cancellationToken: CancellationToken

A CancellationToken untuk mengamati sambil menunggu tugas selesai.

Mengembalikan

Task<DbTransaction>

ValueTask<DbTransaction>

Memberikan Task hasil yang akan digunakan EF. Implementasi metode ini untuk setiap pencegat yang tidak mencoba mengubah hasilnya adalah mengembalikan nilai yang result diteruskan, sering kali menggunakan FromResult<TResult>(TResult)

Pengecualian

OperationCanceledException

CancellationToken Jika dibatalkan.

Keterangan

Metode ini masih dipanggil jika pencegat menekan pembuatan di TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>). Dalam hal ini, result adalah hasil yang dikembalikan oleh TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>).
