DbConnectionInterceptor.ConnectionOpeningAsync(DbConnection, ConnectionEventData, InterceptionResult, CancellationToken) Yöntem

Tanım

EF çağrısı yapmak için hemen önce OpenAsync() çağrılır.

public virtual System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ConnectionOpeningAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ConnectionOpeningAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

Parametreler

connection
DbConnection

Bağlantı.

eventData
ConnectionEventData

Bağlantı hakkında bağlamsal bilgiler.

result
InterceptionResult

Varsa geçerli sonucu temsil eder. Bu değer, önceki IsSuppressed bir kesme true noktası çağrılarak yürütmeyi bastırmışsa olarak Suppress() ayarlanmıştır. Bu değer genellikle bu yöntemin uygulanması için dönüş değeri olarak kullanılır.

cancellationToken
CancellationToken

Görevin CancellationToken tamamlandıktan sonra gözlemlemek için bir.

Döndürülenler

Task<InterceptionResult>
ValueTask<InterceptionResult>

false ise EF normal IsSuppressed şekilde devam eder. true IsSuppressed ise EF, gerçekleştirmek üzere olduğu işlemi bastıracak. Bu yöntemin işlemi gizlemeye çalışan herhangi bir kesme noktası için normal bir uygulaması, geçirilen result değerin geri dönmesidir.
