Called immediately after EF calls ExecuteReaderAsync().

This method is still called if an interceptor suppressed execution of a command in ReaderExecutingAsync(DbCommand, CommandEventData, InterceptionResult<DbDataReader>, CancellationToken). In this case, result is the result returned by 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)

Parameters

command: DbCommand

The command.

eventData: CommandExecutedEventData

Contextual information about the command and execution.

result: DbDataReader

The result of the call to ExecuteReaderAsync(). This value is typically used as the return value for the implementation of this method.

cancellationToken: CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

Task<DbDataReader>

ValueTask<DbDataReader>

A Task providing the result that EF will use. A normal implementation of this method for any interceptor that is not attempting to change the result is to return the result value passed in, often using FromResult<TResult>(TResult)

Implements

ReaderExecutedAsync(DbCommand, CommandExecutedEventData, DbDataReader, CancellationToken)

Exceptions

OperationCanceledException

If the CancellationToken is canceled.
