IDbTransactionInterceptor.TransactionStarting Método

Definição

Namespace:

Microsoft.EntityFrameworkCore.Diagnostics

Assembly:

Microsoft.EntityFrameworkCore.Relational.dll

Pacote:

Microsoft.EntityFrameworkCore.Relational v9.0.0

Origem:

IDbTransactionInterceptor.cs

Chamado pouco antes do EF pretende chamar BeginTransaction(IsolationLevel).

public virtual Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction> TransactionStarting (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.TransactionStartingEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction> result);

abstract member TransactionStarting : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionStartingEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction> -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction>
override this.TransactionStarting : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.TransactionStartingEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction> -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbTransaction>

Public Overridable Function TransactionStarting (connection As DbConnection, eventData As TransactionStartingEventData, result As InterceptionResult(Of DbTransaction)) As InterceptionResult(Of DbTransaction)

Parâmetros

connection

DbConnection

A conexão.

eventData

TransactionStartingEventData

Informações contextuais sobre conexão e transação.

result

InterceptionResult<DbTransaction>

Representa o resultado atual se houver um. Esse valor terá HasResult definido como true se algum interceptador anterior suprimisse a execução chamando SuppressWithResult(TResult). Esse valor normalmente é usado como o valor retornado para a implementação desse método.

Retornos

InterceptionResult<DbTransaction>

Se HasResult for false, o EF continuará normalmente. Se HasResult for true, o EF suprimirá a operação que estava prestes a executar e usar Result . Uma implementação desse método para qualquer interceptador que não está tentando alterar o resultado é retornar o result valor passado, muitas vezes usando FromResult<TResult>(TResult)
