public static System.Collections.Generic.IAsyncEnumerable<TSource> Union<TSource>(this System.Collections.Generic.IAsyncEnumerable<TSource> first, System.Collections.Generic.IAsyncEnumerable<TSource> second, System.Collections.Generic.IEqualityComparer<TSource>? comparer = default);

static member Union : System.Collections.Generic.IAsyncEnumerable<'Source> * System.Collections.Generic.IAsyncEnumerable<'Source> * System.Collections.Generic.IEqualityComparer<'Source> -> System.Collections.Generic.IAsyncEnumerable<'Source>

<Extension()>
Public Function Union(Of TSource) (first As IAsyncEnumerable(Of TSource), second As IAsyncEnumerable(Of TSource), Optional comparer As IEqualityComparer(Of TSource) = Nothing) As IAsyncEnumerable(Of TSource)

Type Parameters

Parameters

first: IAsyncEnumerable<TSource>

An IAsyncEnumerable<T> whose distinct elements form the first set for the union.

second: IAsyncEnumerable<TSource>

An IAsyncEnumerable<T> whose distinct elements form the second set for the union.

comparer: IEqualityComparer<TSource>

An IEqualityComparer<T> to compare keys.

Returns

IAsyncEnumerable<TSource>

An IAsyncEnumerable<T> that contains the elements from both input sequences, excluding duplicates.
