SqlDataReader.NextResultAsync Method (CancellationToken)
An asynchronous version of NextResult, which advances the data reader to the next result, when reading the results of batch Transact-SQL statements.
The cancellation token can be used to request that the operation be abandoned before the command timeout elapses. Exceptions will be reported via the returned Task object.
Assembly: System.Data (in System.Data.dll)
