ParallelEnumerable.AsParallel ParallelEnumerable.AsParallel ParallelEnumerable.AsParallel ParallelEnumerable.AsParallel Method

啟用查詢的平行化作業。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

備註

Cast運算子可以用來轉換 ParallelQuery(T) ParallelQuery。The Cast operator can be used to convert a ParallelQuery to a ParallelQuery(T).

啟用查詢的平行化作業，此時則指定負責將輸入序列分成多個分割的自訂 Partitioner 處理來源。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)

備註

來源的 partitioner GetOrderedPartitions 排序時，方法使用已啟用，而如果不排序，則用 partitioner GetPartitions 啟用 （預設值）。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). 不會使用來源的 partitioner GetDynamicPartitions 和 GetDynamicOrderedPartitions。The source partitioner's GetDynamicPartitions and GetDynamicOrderedPartitions are not used. 如需詳細資訊和範例，請參閱 < PLINQ 和 TPL 的自訂 Partitioner。For more information and examples, see Custom Partitioners for PLINQ and TPL.
