ParallelEnumerable.Except<'TSource> Method (ParallelQuery<'TSource>, IEnumerable<'TSource>)

.NET Framework (current version)
 
Note: This API is now obsolete.

This Except 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)

[<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 member Except<'TSource> : 
        first:ParallelQuery<'TSource> *
        second:IEnumerable<'TSource> -> ParallelQuery<'TSource>

Parameters

first
Type: System.Linq.ParallelQuery<'TSource>

This parameter is not used.

second
Type: System.Collections.Generic.IEnumerable<'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.

Exception Condition
NotSupportedException

The exception that occurs when this method is called.

This overload exists to disallow usage of Except with a left data source of type ParallelQuery<'TSource> and a right data source of type IEnumerable<'T>. Otherwise, the Except operator would appear to be binding to the parallel implementation, but would in reality bind to the sequential implementation.
