ParallelEnumerable.AsParallel Method

Definition

Namespace:

System.Linq

Assembly:

System.Linq.Parallel.dll

Enables parallelization of a query.

Overloads

AsParallel(IEnumerable)	Enables parallelization of a query.
AsParallel<TSource>(Partitioner<TSource>)	Enables parallelization of a query, as sourced by a custom partitioner that is responsible for splitting the input sequence into partitions.
AsParallel<TSource>(IEnumerable<TSource>)	Enables parallelization of a query.

Remarks

This method binds the query to PLINQ. For more information, see Parallel LINQ (PLINQ).

AsParallel(IEnumerable)

Source:

ParallelEnumerable.cs

Enables parallelization of a query.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Linq::ParallelQuery ^ AsParallel(System::Collections::IEnumerable ^ source);

public static System.Linq.ParallelQuery AsParallel (this System.Collections.IEnumerable source);

static member AsParallel : System.Collections.IEnumerable -> System.Linq.ParallelQuery

<Extension()>
Public Function AsParallel (source As IEnumerable) As ParallelQuery

Parameters

source

IEnumerable

An IEnumerable<T> to convert to a ParallelQuery.

Returns

ParallelQuery

The source as a ParallelQuery to bind to ParallelEnumerable extension methods.

Exceptions

ArgumentNullException

source is a null reference (Nothing in Visual Basic).

Remarks

The Cast operator can be used to convert a ParallelQuery to a ParallelQuery(T).

AsParallel<TSource>(Partitioner<TSource>)

Source:

ParallelEnumerable.cs

Enables parallelization of a query, as sourced by a custom partitioner that is responsible for splitting the input sequence into partitions.

public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static System::Linq::ParallelQuery<TSource> ^ AsParallel(System::Collections::Concurrent::Partitioner<TSource> ^ source);

public static System.Linq.ParallelQuery<TSource> AsParallel<TSource> (this System.Collections.Concurrent.Partitioner<TSource> source);

static member AsParallel : System.Collections.Concurrent.Partitioner<'Source> -> System.Linq.ParallelQuery<'Source>

<Extension()>
Public Function AsParallel(Of TSource) (source As Partitioner(Of TSource)) As ParallelQuery(Of TSource)

Type Parameters

TSource

The type of elements of source.

Parameters

source

Partitioner<TSource>

A partitioner over the input sequence.

Returns

ParallelQuery<TSource>

The source as a ParallelQuery to bind to ParallelEnumerable extension methods.

Exceptions

ArgumentNullException

source is a null reference (Nothing in Visual Basic).

Remarks

The source partitioner's GetOrderedPartitions method is used when ordering is enabled, whereas the partitioner's GetPartitions is used if ordering is not enabled (the default). The source partitioner's GetDynamicPartitions and GetDynamicOrderedPartitions are not used. For more information and examples, see Custom Partitioners for PLINQ and TPL.

Type Parameters

Parameters
