ExecuteReaderAsync(IDbCommand, CommandBehavior, CancellationToken)

If the command is derived from DbCommand, this will call ExecuteReaderAsync(CommandBehavior, CancellationToken); otherwise it will call ExecuteReader(CommandBehavior).

public static ValueTask<IDataReader> ExecuteReaderAsync(this IDbCommand command, CommandBehavior behavior = CommandBehavior.Default, CancellationToken cancellationToken = default)

Parameters

command IDbCommand

The DbCommand to generate a reader from.

behavior CommandBehavior

The behavior to use with the data reader.

cancellationToken CancellationToken

The cancellation token.

Returns

ValueTask<IDataReader>

ExecuteReaderAsync(DbCommand, Action<DbDataReader>, CommandBehavior, CancellationToken)
