DbDataReader.NextResultAsync DbDataReader.NextResultAsync DbDataReader.NextResultAsync DbDataReader.NextResultAsync Method

Definition

Implements the asynchronous version of NextResult(), but returns a Task synchronously, blocking the calling thread.

Overloads

NextResultAsync() NextResultAsync() NextResultAsync() NextResultAsync()

An asynchronous version of NextResult(), which advances the reader to the next result when reading the results of a batch of statements.

Invokes NextResultAsync(CancellationToken) with CancellationToken.None.

NextResultAsync(CancellationToken) NextResultAsync(CancellationToken) NextResultAsync(CancellationToken)

This is the asynchronous version of NextResult(). Providers should override with an appropriate implementation. The cancellationToken may optionally be ignored.

The default implementation invokes the synchronous NextResult() method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by NextResult() will be communicated via the returned Task Exception property.

Other methods and properties of the DbDataReader object should not be invoked while the returned Task is not yet completed.
