ParallelEnumerable.Last Method

Definition

Returns the last element of a parallel sequence.

Overloads

Last<TSource>(ParallelQuery<TSource>)

Returns the last element of a parallel sequence.

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

Returns the last element of a parallel sequence that satisfies a specified condition.

Last<TSource>(ParallelQuery<TSource>)

Returns the last element of a parallel sequence.

public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static TSource Last(System::Linq::ParallelQuery<TSource> ^ source);
public static TSource Last<TSource> (this System.Linq.ParallelQuery<TSource> source);
static member Last : System.Linq.ParallelQuery<'Source> -> 'Source
<Extension()>
Public Function Last(Of TSource) (source As ParallelQuery(Of TSource)) As TSource

Type Parameters

TSource

The type of the elements of source.

Parameters

source
ParallelQuery<TSource>

The sequence to return the last element from.

Returns

TSource

The value at the last position in the source sequence.

Exceptions

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

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

source contains no elements.

Remarks

If the query is not ordered, then the last element is non-deterministic. For more information, see Order Preservation in PLINQ.

Type Parameters

TSource

The type of the elements of source.

Parameters

source
ParallelQuery<TSource>

The sequence to return an element from.

predicate
Func<TSource,Boolean>

A function to test each element for a condition.

Returns

TSource

The last element in the sequence that passes the test in the specified predicate function.

Exceptions

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

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

No element in source satisfies the condition in predicate.

Remarks

If the query is not ordered, then the last element is non-deterministic. For more information, see Order Preservation in PLINQ.
