Public Function Last(Of TSource) (source As ParallelQuery(Of TSource)) As TSourceType Parameters
- TSource
The type of the elements of source.
Parameters
- source
- ParallelQuery<TSource>
The sequence to return the last element from.
Returns
The value at the last position in the source sequence.
Exceptions
The query was canceled with the token passed in through WithCancellation<TSource>(ParallelQuery<TSource>, CancellationToken).
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.

Public Function Last(Of TSource) (source As ParallelQuery(Of TSource), predicate As Func(Of TSource, Boolean)) As TSourceType Parameters
- TSource
The type of the elements of source.
Parameters
- source
- ParallelQuery<TSource>
The sequence to return an element from.
Returns
The last element in the sequence that passes the test in the specified predicate function.
Exceptions
The query was canceled with the token passed in through WithCancellation<TSource>(ParallelQuery<TSource>, CancellationToken).
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.
