ParallelEnumerable.TakeWhile ParallelEnumerable.TakeWhile ParallelEnumerable.TakeWhile ParallelEnumerable.TakeWhile Method

Definition

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 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

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

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

Exceptions

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

The query was canceled with the token passed in through WithCancellation.

More than MaxValue elements are enumerated by this query.

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