DbCommand.ExecuteReaderAsync Method

Definition

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

Overloads

ExecuteReaderAsync()

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

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

ExecuteReaderAsync(CommandBehavior)

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

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

ExecuteReaderAsync(CancellationToken)

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

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

ExecuteReaderAsync(CommandBehavior, CancellationToken)

Invokes ExecuteDbDataReaderAsync(CommandBehavior, CancellationToken).

Remarks

Managed provider implementers must call ExecuteDbDataReaderAsync in ExecuteReaderAsync. For more information about asynchronous programming, see Asynchronous Programming.
