IDbTransactionInterceptor.TransactionRollingBackAsync Metoda

Definice

Volá se těsně před tím, než EF hodlá volat RollbackAsync(CancellationToken).

public System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> TransactionRollingBackAsync (System.Data.Common.DbTransaction transaction, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);
public System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> TransactionRollingBackAsync (System.Data.Common.DbTransaction transaction, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

Parametry

transaction
DbTransaction

Transakce.

eventData
TransactionEventData

Kontextové informace o připojení a transakci.

result
InterceptionResult

Představuje aktuální výsledek, pokud existuje. Tato hodnota bude nastavena IsSuppressed na true , pokud některý předchozí zachytávací modul potlačil spuštění 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

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

Výjimky
