ParallelEnumerable.Except Method

Definition

Produces the set difference of two parallel sequences.

Overloads

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

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

Except<TSource>(ParallelQuery<TSource>, ParallelQuery<TSource>)

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

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

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

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

Produces the set difference of two parallel sequences by using the specified IEqualityComparer<T> 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>.

static member Except : System.Linq.ParallelQuery<'Source> * seq<'Source> -> System.Linq.ParallelQuery<'Source>
<Extension()>
Public Function Except(Of TSource) (first As ParallelQuery(Of TSource), second As IEnumerable(Of TSource)) As ParallelQuery(Of TSource)

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.

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 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.

<Extension()>
Public Function Except(Of TSource) (first As ParallelQuery(Of TSource), second As ParallelQuery(Of TSource)) As ParallelQuery(Of TSource)

Type Parameters

TSource

The type of the elements of the input sequences.

Parameters

first
ParallelQuery<TSource>

A sequence whose elements that are not also in second will be returned.

second
ParallelQuery<TSource>

A sequence whose elements that also occur in the first sequence will cause those elements to be removed from the returned sequence.

Returns

A sequence that contains the set difference of the elements of two sequences.

Exceptions

first or second is a null reference (Nothing in Visual Basic).

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