[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>.")] public static ParallelQuery<TSource> Intersect<TSource>( this ParallelQuery<TSource> first, IEnumerable<TSource> second, IEqualityComparer<TSource> comparer )

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

Type Parameters
- TSource
This type parameter is not used.
| 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.
