Public Function Count(Of TSource) (source As ParallelQuery(Of TSource)) As IntegerType Parameters
- TSource
The type of the elements of source.
Parameters
- source
- ParallelQuery<TSource>
A sequence that contains elements to be counted.
Returns
The number of elements in the input 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).
The number of elements in source is larger than Int32.MaxValue. (In this case the InnerException is OverflowException) -or- One or more exceptions occurred during the evaluation of the query.

Public Function Count(Of TSource) (source As ParallelQuery(Of TSource), predicate As Func(Of TSource, Boolean)) As IntegerType Parameters
- TSource
The type of the elements of source.
Parameters
- source
- ParallelQuery<TSource>
A sequence that contains elements to be counted.
Returns
A number that represents how many elements in the sequence satisfy the condition in the 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).
The number of elements in source is larger than Int32.MaxValue. (In this case the InnerException is OverflowException) -or- One or more exceptions occurred during the evaluation of the query.
