DbCommand.ExecuteReaderAsync Method (System.Data.Common) | Microsoft Learn

An asynchronous version of ExecuteReader, which executes the command against its connection, returning a DbDataReader that can be used to access the results.

An asynchronous version of ExecuteReader, which executes the command against its connection, returning a DbDataReader that can be used to access the results.

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken) with CancellationToken.None.

Public Function ExecuteReaderAsync () As Task(Of DbDataReader)

A task representing the asynchronous operation.

An error occurred while executing the command.

This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by ExecuteReader().
