ToList<TSource>(ParallelQuery<TSource>)

Creates a List<T> from an ParallelQuery<TSource>.

ToLookup<TSource,TKey,TElement>(ParallelQuery<TSource>, Func<TSource,TKey>, Func<TSource,TElement>)

Creates an ILookup<TKey,TElement> from a ParallelQuery<TSource> according to specified key selector and element selector functions.

ToLookup<TSource,TKey,TElement>(ParallelQuery<TSource>, Func<TSource,TKey>, Func<TSource,TElement>, IEqualityComparer<TKey>)

Creates an ILookup<TKey,TElement> from a ParallelQuery<TSource> according to a specified key selector function, a comparer and an element selector function.

ToLookup<TSource,TKey>(ParallelQuery<TSource>, Func<TSource,TKey>)

Creates an ILookup<TKey,TElement> from a ParallelQuery<TSource> according to a specified key selector function.

ToLookup<TSource,TKey>(ParallelQuery<TSource>, Func<TSource,TKey>, IEqualityComparer<TKey>)

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

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

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

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

Union<TSource>(ParallelQuery<TSource>, ParallelQuery<TSource>)

Produces the set union of two parallel sequences by using the default equality comparer.

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

Produces the set union of two parallel sequences by using a specified IEqualityComparer{T}.

Where<TSource>(ParallelQuery<TSource>, Func<TSource,Boolean>)

Filters in parallel a sequence of values based on a predicate.

Where<TSource>(ParallelQuery<TSource>, Func<TSource,Int32,Boolean>)

Filters in parallel a sequence of values based on a predicate. Each element's index is used in the logic of the predicate function.

WithCancellation<TSource>(ParallelQuery<TSource>, CancellationToken)

Sets the CancellationToken to associate with the query.

WithDegreeOfParallelism<TSource>(ParallelQuery<TSource>, Int32)

Sets the degree of parallelism to use in a query. Degree of parallelism is the maximum number of concurrently executing tasks that will be used to process the query.

WithExecutionMode<TSource>(ParallelQuery<TSource>, ParallelExecutionMode)

Sets the execution mode of the query.

WithMergeOptions<TSource>(ParallelQuery<TSource>, ParallelMergeOptions)

Sets the merge options for this query, which specify how the query will buffer output.

Zip<TFirst,TSecond,TResult>(ParallelQuery<TFirst>, IEnumerable<TSecond>, Func<TFirst,TSecond,TResult>)
Obsolete.

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

Zip<TFirst,TSecond,TResult>(ParallelQuery<TFirst>, ParallelQuery<TSecond>, Func<TFirst,TSecond,TResult>)

Merges in parallel two sequences by using the specified predicate function.
