Dipanggil segera setelah EF memanggil ExecuteReaderAsync().

Metode ini masih dipanggil jika pencegat menekan eksekusi perintah di ReaderExecutingAsync(DbCommand, CommandEventData, InterceptionResult<DbDataReader>, CancellationToken). Dalam hal ini, result adalah hasil yang dikembalikan oleh ReaderExecutingAsync(DbCommand, CommandEventData, InterceptionResult<DbDataReader>, CancellationToken).

public virtual System.Threading.Tasks.Task<System.Data.Common.DbDataReader> ReaderExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, System.Data.Common.DbDataReader result, System.Threading.CancellationToken cancellationToken = default);

public virtual System.Threading.Tasks.ValueTask<System.Data.Common.DbDataReader> ReaderExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, System.Data.Common.DbDataReader result, System.Threading.CancellationToken cancellationToken = default);

abstract member ReaderExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * System.Data.Common.DbDataReader * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbDataReader>
override this.ReaderExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * System.Data.Common.DbDataReader * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Common.DbDataReader>

Public Overridable Function ReaderExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As DbDataReader, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DbDataReader)

Public Overridable Function ReaderExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As DbDataReader, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of DbDataReader)

Parameter

command: DbCommand

Perintah.

eventData: CommandExecutedEventData

Informasi kontekstual tentang perintah dan eksekusi.

result: DbDataReader

Hasil panggilan ke ExecuteReaderAsync(). Nilai ini biasanya digunakan sebagai nilai pengembalian untuk implementasi metode ini.

cancellationToken: CancellationToken

A CancellationToken untuk mengamati sambil menunggu tugas selesai.

Mengembalikan

Task<DbDataReader>

ValueTask<DbDataReader>

Memberikan Task hasil yang akan digunakan EF. Implementasi normal dari metode ini untuk setiap pencegat yang tidak mencoba mengubah hasilnya adalah mengembalikan nilai yang result diteruskan, sering menggunakan FromResult<TResult>(TResult)

Penerapan

ReaderExecutedAsync(DbCommand, CommandExecutedEventData, DbDataReader, CancellationToken)

Pengecualian

OperationCanceledException

CancellationToken Jika dibatalkan.
