Returns elements from a sequence as long as a specified condition is true.

public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static System::Collections::Generic::IAsyncEnumerable<TSource> ^ TakeWhile(System::Collections::Generic::IAsyncEnumerable<TSource> ^ source, Func<TSource, bool> ^ predicate);

static member TakeWhile : System.Collections.Generic.IAsyncEnumerable<'Source> * Func<'Source, bool> -> System.Collections.Generic.IAsyncEnumerable<'Source>

<Extension()>
Public Function TakeWhile(Of TSource) (source As IAsyncEnumerable(Of TSource), predicate As Func(Of TSource, Boolean)) As IAsyncEnumerable(Of TSource)

Type Parameters

TSource

The type of the elements of source.

Parameters

predicate

Func<TSource,Boolean>

A function to test each element for a condition.

Returns

An IAsyncEnumerable that contains the elements from the input sequence that occur before the element at which the test no longer passes.

Exceptions

Applies to

TakeWhile(IAsyncEnumerable, Func<TSource,Int32,Boolean>)

Source:

TakeWhile.cs

Source:

TakeWhile.cs

Returns elements from a sequence as long as a specified condition is true. The element's index is used in the logic of the predicate function.

static member TakeWhile : System.Collections.Generic.IAsyncEnumerable<'Source> * Func<'Source, int, bool> -> System.Collections.Generic.IAsyncEnumerable<'Source>

<Extension()>
Public Function TakeWhile(Of TSource) (source As IAsyncEnumerable(Of TSource), predicate As Func(Of TSource, Integer, Boolean)) As IAsyncEnumerable(Of TSource)

Type Parameters

TSource

The type of the elements of source.

Parameters

predicate

Func<TSource,Int32,Boolean>

A function to test each element for a condition.

Returns

An IAsyncEnumerable that contains the elements from the input sequence that occur before the element at which the test no longer passes.
