Returns elements from a parallel sequence as long as a specified condition is true.

Overloads

TakeWhile<TSource>(ParallelQuery<TSource>, Func<TSource,Int32,Boolean>)	Returns elements from a parallel sequence as long as a specified condition is true. The element's index is used in the logic of the predicate function.
TakeWhile<TSource>(ParallelQuery<TSource>, Func<TSource,Boolean>)	Returns elements from a parallel sequence as long as a specified condition is true.

Returns elements from a parallel sequence as long as a specified condition is true. The element's index is used in the logic of the predicate function.

public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static System::Linq::ParallelQuery<TSource> ^ TakeWhile(System::Linq::ParallelQuery<TSource> ^ source, Func<TSource, int, bool> ^ predicate);

public static System.Linq.ParallelQuery<TSource> TakeWhile<TSource> (this System.Linq.ParallelQuery<TSource> source, Func<TSource,int,bool> predicate);

static member TakeWhile : System.Linq.ParallelQuery<'Source> * Func<'Source, int, bool> -> System.Linq.ParallelQuery<'Source>

<Extension()>
Public Function TakeWhile(Of TSource) (source As ParallelQuery(Of TSource), predicate As Func(Of TSource, Integer, Boolean)) As ParallelQuery(Of TSource)

Type Parameters

TSource

The type of elements of source.

Parameters

source: ParallelQuery<TSource>

The sequence to return elements from.

predicate: Func<TSource,Int32,Boolean>

A function to test each source element for a condition; the second parameter of the function represents the index of the source element.

Returns

ParallelQuery<TSource>

A sequence that contains elements from the input sequence that occur before the element at which the test no longer passes.

Exceptions

ArgumentNullException

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

OperationCanceledException

The query was canceled with the token passed in through WithCancellation<TSource>(ParallelQuery<TSource>, CancellationToken).

OverflowException

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

AggregateException

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