DbDataReader.NextResultAsync Method (CancellationToken)

.NET Framework 4.5

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.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)
