<Extension()>
Public Function ToDictionary(Of TSource, TKey, TElement) (source As ParallelQuery(Of TSource), keySelector As Func(Of TSource, TKey), elementSelector As Func(Of TSource, TElement), comparer As IEqualityComparer(Of TKey)) As Dictionary(Of TKey, TElement)

Type Parameters

TSource

The type of the elements of source.

TKey

The type of the key returned by keySelector.

TElement

The type of the value returned by elementSelector.

Parameters

keySelector: Func<TSource,TKey>

A function to extract a key from each element.

elementSelector: Func<TSource,TElement>

A transform function to produce a result element value from each element.

Returns

A Dictionary<TKey,TValue> that contains values of type TElement selected from the input sequence.

Exceptions

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

keySelector produces a key that is a null reference (Nothing in Visual Basic). -or- keySelector produces duplicate keys for two elements. -or- One or more exceptions occurred during the evaluation of the query.
