Determines whether two parallel sequences are equal by comparing the elements by using an equality comparer for their type.

Caution
The second data source of a binary operator must be of type System.Linq.ParallelQuery<T> rather than System.Collections.Generic.IEnumerable<T>. To fix this problem, use the AsParallel() extension method to convert the right data source to System.Linq.ParallelQuery<T>.

Public Function SequenceEqual(Of TSource) (first As ParallelQuery(Of TSource), second As IEnumerable(Of TSource)) As BooleanType Parameters
- TSource
This type parameter is not used.
Parameters
- first
- ParallelQuery<TSource>
This parameter is not used.
- second
- IEnumerable<TSource>
This parameter is not used.
Returns
This overload always throws a NotSupportedException.
- Attributes
Exceptions
Thrown every time this method is called.
Remarks
This overload exists to disallow usage of SequenceEqual with a left data source of type ParallelQuery<TSource> and a right data source of type IEnumerable<T>. Otherwise, the SequenceEqual operator would appear to be binding to the parallel implementation, but would in reality bind to the sequential implementation.

Public Function SequenceEqual(Of TSource) (first As ParallelQuery(Of TSource), second As ParallelQuery(Of TSource)) As BooleanType Parameters
- TSource
The type of the elements of the input sequences.
Parameters
- first
- ParallelQuery<TSource>
A sequence to compare to second.
- second
- ParallelQuery<TSource>
A sequence to compare to the first input sequence.
Returns
true if the two source sequences are of equal length and their corresponding elements are equal according to the default equality comparer for their type; otherwise, false.
Exceptions
The query was canceled with the token passed in through WithCancellation<TSource>(ParallelQuery<TSource>, CancellationToken).
first or second is a null reference (Nothing in Visual Basic).
One or more exceptions occurred during the evaluation of the query.
