ParallelEnumerable.Intersect Method

Definition

Produces the set intersection of two parallel sequences.

Overloads

Intersect<TSource>(ParallelQuery<TSource>, IEnumerable<TSource>, IEqualityComparer<TSource>)
Obsolete.

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

Intersect<TSource>(ParallelQuery<TSource>, ParallelQuery<TSource>, IEqualityComparer<TSource>)

Produces the set intersection of two parallel sequences by using the specified IEqualityComparer{T} to compare values.

Intersect<TSource>(ParallelQuery<TSource>, IEnumerable<TSource>)
Obsolete.

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

Intersect<TSource>(ParallelQuery<TSource>, ParallelQuery<TSource>)

Produces the set intersection of two parallel sequences by using the default equality comparer to compare values.

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>.

Type 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.

comparer
IEqualityComparer<TSource>

This parameter is not used.

Returns

This overload always throws a NotSupportedException.

Attributes

Exceptions

The exception that occurs when this method is called.

Remarks

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.

Type Parameters

TSource

The type of the elements of the input sequences.

Parameters

first
ParallelQuery<TSource>

A sequence whose distinct elements that also appear in second will be returned.

second
ParallelQuery<TSource>

A sequence whose distinct elements that also appear in the first sequence will be returned.

comparer
IEqualityComparer<TSource>

An IEqualityComparer<T> to compare values.

Returns

A sequence that contains the elements that form the set intersection of two sequences.

Exceptions

source or action is a null reference (Nothing in Visual Basic).

One or more exceptions occurred during the evaluation of the query.
