ParallelEnumerable.Where Method

Definition

Filters in parallel a sequence of values based on a predicate.

Overloads

Where<TSource>(ParallelQuery<TSource>, Func<TSource,Boolean>)

Filters in parallel a sequence of values based on a predicate.

Where<TSource>(ParallelQuery<TSource>, Func<TSource,Int32,Boolean>)

Filters in parallel a sequence of values based on a predicate. Each element's index is used in the logic of the predicate function.

Filters in parallel a sequence of values based on a predicate.

public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static System::Linq::ParallelQuery<TSource> ^ Where(System::Linq::ParallelQuery<TSource> ^ source, Func<TSource, bool> ^ predicate);
public static System.Linq.ParallelQuery<TSource> Where<TSource> (this System.Linq.ParallelQuery<TSource> source, Func<TSource,bool> predicate);
static member Where : System.Linq.ParallelQuery<'Source> * Func<'Source, bool> -> System.Linq.ParallelQuery<'Source>
<Extension()>
Public Function Where(Of TSource) (source As ParallelQuery(Of TSource), predicate As Func(Of TSource, Boolean)) As ParallelQuery(Of TSource)

Type Parameters

TSource

The type of the elements of source.

Parameters

source
ParallelQuery<TSource>

A sequence to filter.

predicate
Func<TSource,Boolean>

A function to test each element for a condition.

Returns

A sequence that contains elements from the input sequence that satisfy the condition.

Exceptions

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

One or more exceptions occurred during the evaluation of the query.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
ParallelQuery<TSource>

A sequence to filter.

predicate
Func<TSource,Int32,Boolean>

A function to test each element for a condition.

Returns

A sequence that contains elements from the input sequence that satisfy the condition.

Exceptions

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

More than Int32.MaxValue elements are enumerated by the query.

One or more exceptions occurred during the evaluation of the query.
