Determines whether a sequence contains any elements.

public static System.Threading.Tasks.ValueTask<bool> AnyAsync<TSource>(this System.Collections.Generic.IAsyncEnumerable<TSource> source, System.Threading.CancellationToken cancellationToken = default);

static member AnyAsync : System.Collections.Generic.IAsyncEnumerable<'Source> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<bool>

<Extension()>
Public Function AnyAsync(Of TSource) (source As IAsyncEnumerable(Of TSource), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Boolean)

Type Parameters

TSource

The type of the elements of source.

Parameters

Returns

true if the source sequence contains any elements; otherwise, false.

Source:

AnyAsync.cs

Determines whether any element of a sequence satisfies a condition.

public static System.Threading.Tasks.ValueTask<bool> AnyAsync<TSource>(this System.Collections.Generic.IAsyncEnumerable<TSource> source, Func<TSource,bool> predicate, System.Threading.CancellationToken cancellationToken = default);

static member AnyAsync : System.Collections.Generic.IAsyncEnumerable<'Source> * Func<'Source, bool> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<bool>

<Extension()>
Public Function AnyAsync(Of TSource) (source As IAsyncEnumerable(Of TSource), predicate As Func(Of TSource, Boolean), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Boolean)

Type Parameters

Parameters

predicate

Func<TSource,Boolean>

A function to test each element for a condition.

Returns

true if the source sequence is not empty and at least one of its elements passes the test in the specified predicate; otherwise, false.
