DbTransactionInterceptor.TransactionStartedAsync Metodo

Definizione

Chiamato immediatamente dopo che EF chiama BeginTransactionAsync(IsolationLevel, CancellationToken) .

Questo metodo viene comunque chiamato se la creazione di un intercettore è stata eliminata in TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>). In questo caso, result è il risultato restituito da TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>).

public virtual System.Threading.Tasks.Task<System.Data.Common.DbTransaction> TransactionStartedAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData eventData, System.Data.Common.DbTransaction result, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction> TransactionStartedAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData eventData, System.Data.Common.DbTransaction result, System.Threading.CancellationToken cancellationToken = default);
abstract member TransactionStartedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbTransaction>
override this.TransactionStartedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbTransaction>
abstract member TransactionStartedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
override this.TransactionStartedAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionEndEventData * System.Data.Common.DbTransaction * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.Data.Common.DbTransaction>
Public Overridable Function TransactionStartedAsync (connection As DbConnection, eventData As TransactionEndEventData, result As DbTransaction, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DbTransaction)
Public Overridable Function TransactionStartedAsync (connection As DbConnection, eventData As TransactionEndEventData, result As DbTransaction, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of DbTransaction)

Parametri

connection
DbConnection

Connessione.

eventData
TransactionEndEventData

Informazioni contestuali sulla connessione e sulla transazione.

result
DbTransaction

Risultato della chiamata a BeginTransactionAsync(IsolationLevel, CancellationToken). Questo valore viene in genere usato come valore restituito per l'implementazione di questo metodo.

cancellationToken
CancellationToken

Oggetto CancellationToken da osservare durante l'attesa del completamento dell'attività.

Restituisce

Oggetto Task che fornisce il risultato che ef userà. Un'implementazione normale di questo metodo per qualsiasi intercettore che non tenta di modificare il risultato consiste nel restituire il result valore passato, spesso utilizzando FromResult<TResult>(TResult)
