IDbTransactionInterceptor.TransactionStartedAsync Yöntem

Tanım

EF çağrısı yaptıktan hemen sonra çağrılır BeginTransactionAsync(IsolationLevel, CancellationToken).

public 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 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);
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);

Parametreler

connection
DbConnection

Bağlantı.

eventData
TransactionEndEventData

Bağlantı ve işlem hakkında bağlamsal bilgiler.

result
DbTransaction

çağrısının BeginTransactionAsync(IsolationLevel, CancellationToken)sonucu. Bu değer genellikle bu yöntemin uygulanması için dönüş değeri olarak kullanılır.

cancellationToken
CancellationToken

CancellationToken Görevin tamamlanmasını beklerken gözlemlemek için bir.

Döndürülenler

Task EF'nin kullanacağı sonucu sağlayan. Sonucu değiştirmeye çalışmayan herhangi bir kesme noktası için bu yöntemin bir uygulaması, genellikle kullanarak geçirilen değeri döndürmektir resultFromResult<TResult>(TResult)

Özel durumlar

Açıklamalar

Bir kesme noktası içinde oluşturma işlemini engellediyse bu yöntem hala çağrılır TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>). Bu durumda, result tarafından TransactionStarting(DbConnection, TransactionStartingEventData, InterceptionResult<DbTransaction>)döndürülen sonuç olur.
