ParallelEnumerable.TakeWhile Method

Definition

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.

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

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

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).

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

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