ParallelEnumerable::Intersect<TSource> Method (ParallelQuery<TSource>^, IEnumerable<TSource>^, IEqualityComparer<TSource>^)

.NET Framework (current version)

Note: This API is now obsolete.

This Intersect overload should never be called. This method is marked as obsolete and always throws NotSupportedException when called.

Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)

Syntax

C++

public:
generic<typename TSource>
[ExtensionAttribute]
[ObsoleteAttribute("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>.")]
static ParallelQuery<TSource>^ Intersect(
	ParallelQuery<TSource>^ first,
	IEnumerable<TSource>^ second,
	IEqualityComparer<TSource>^ comparer
)

Parameters

first: Type: System.Linq::ParallelQuery<TSource>^
This parameter is not used.

second: Type: System.Collections.Generic::IEnumerable<TSource>^
This parameter is not used.

comparer: Type: System.Collections.Generic::IEqualityComparer<TSource>^
This parameter is not used.

Return Value

Type: System.Linq::ParallelQuery<TSource>^

This overload always throws a NotSupportedException.

Type Parameters

TSource: This type parameter is not used.

Exceptions

Exception	Condition
NotSupportedException	The exception that occurs when this method is called.

This overload exists to disallow usage of Intersect with a left data source of type ParallelQuery<TSource> and a right data source of type IEnumerable<T>. Otherwise, the Intersect operator would appear to be binding to the parallel implementation, but would in reality bind to the sequential implementation.
