Parametreler

connection
DbConnection

Bağlantı.

eventData
TransactionStartingEventData

Bağlantı ve işlem hakkında bağlamsal bilgiler.

result
InterceptionResult<DbTransaction>

Varsa geçerli sonucu temsil eder. Önceki bir kesme noktası tarafından çağrılarak trueSuppressWithResult(TResult)yürütme engellendiyse bu değer HasResult olarak ayarlanır. Bu değer genellikle bu yöntemin uygulanması için dönüş değeri olarak kullanılır.

Döndürülenler

InterceptionResult<DbTransaction>

HasResult False ise EF normal şekilde devam eder. True HasResult ise, EF gerçekleştirmek üzere olduğu işlemi gizler ve bunun yerine kullanır Result . Sonucu değiştirmeye çalışmayan herhangi bir kesme noktası için bu yöntemin bir uygulaması, genellikle kullanarak geçirilen değeri döndürmektir resultFromResult<TResult>(TResult)

Şunlara uygulanır
