Enables parallelization of a query, as sourced by a partitioner
responsible for splitting the input sequence into partitions.
Namespace:

public static ParallelQuery<TSource> AsParallel<TSource>( Partitioner<TSource> source ) |
Parameters
- source
- Type: System.Collections.Concurrent..::.Partitioner<(Of <(TSource>)>)
A partitioner over the input sequence.
Type Parameters
- TSource
- The type of elements of source.

The source as a ParallelQuery to bind to ParallelEnumerable extension methods.Remarks
The source partitioner's GetOrderedPartitions method is used when ordering is enabled,
