IDbCommandInterceptor.ScalarExecutedAsync Método

Definición

Se llama inmediatamente después de llamar a EF.ExecuteScalarAsync()

public System.Threading.Tasks.Task<object> ScalarExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, object result, System.Threading.CancellationToken cancellationToken = default);
public System.Threading.Tasks.ValueTask<object> ScalarExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, object result, System.Threading.CancellationToken cancellationToken = default);
public System.Threading.Tasks.ValueTask<object?> ScalarExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, object? result, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.ValueTask<object?> ScalarExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, object? result, System.Threading.CancellationToken cancellationToken = default);
abstract member ScalarExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * obj * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>
abstract member ScalarExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * obj * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<obj>
abstract member ScalarExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * obj * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<obj>
override this.ScalarExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * obj * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<obj>
Public Function ScalarExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As Object, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Object)
Public Function ScalarExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As Object, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Object)
Public Overridable Function ScalarExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As Object, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Object)

Parámetros

command
DbCommand

El comando.

eventData
CommandExecutedEventData

Información contextual sobre el comando y la ejecución.

result
Object

Resultado de la llamada a ExecuteScalarAsync(). Este valor se usa normalmente como valor devuelto para la implementación de este método.

cancellationToken
CancellationToken

Que CancellationToken se debe observar mientras se espera a que se complete la tarea.

Devoluciones

Que Task proporciona el resultado que EF usará. Una implementación de este método para cualquier interceptor que no intente cambiar el resultado es devolver el result valor pasado, a menudo usando FromResult<TResult>(TResult)

Excepciones

Comentarios

Se sigue llamando a este método si un interceptor suprimió la ejecución de un comando en ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken). En este caso, result es el resultado devuelto por ScalarExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Object>, CancellationToken).
