Public Function Contains(Of TSource) (source As ParallelQuery(Of TSource), value As TSource, comparer As IEqualityComparer(Of TSource)) As BooleanType Parameters
- TSource
The type of elements of source.
Parameters
- source
- ParallelQuery<TSource>
A sequence in which to locate a value.
- value
- TSource
The value to locate in the sequence.
- comparer
- IEqualityComparer<TSource>
An equality comparer to compare values.
Returns
true if the source sequence contains an element that has the specified value; otherwise, false.
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.
