Take<TSource>(IAsyncEnumerable<TSource>, Int32)

- Take.cs
Returns a specified number of contiguous elements from the start of a sequence.

Public Function Take(Of TSource) (source As IAsyncEnumerable(Of TSource), count As Integer) As IAsyncEnumerable(Of TSource)Type Parameters
- TSource
The type of the elements of source.
Parameters
- source
- IAsyncEnumerable<TSource>
The sequence to return elements from.
- count
- Int32
The number of elements to return.
Returns
An IAsyncEnumerable<T> that contains the specified number of elements from the start of the input sequence.
Exceptions
source is null.
Applies to
Take<TSource>(IAsyncEnumerable<TSource>, Range)
- Source:
- Take.cs
Returns a specified range of contiguous elements from a sequence.

Public Function Take(Of TSource) (source As IAsyncEnumerable(Of TSource), range As Range) As IAsyncEnumerable(Of TSource)Type Parameters
- TSource
The type of the elements of source.
Parameters
- source
- IAsyncEnumerable<TSource>
The sequence to return elements from.
- range
- Range
The range of elements to return, which has start and end indexes either from the start or the end.
Returns
An IAsyncEnumerable<T> that contains the specified range of elements from the source sequence.
Exceptions
source is null.
Remarks
This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its `GetEnumerator` method directly or by using `foreach` in Visual C# or `For Each` in Visual Basic.
Take enumerates source and yields elements whose indices belong to the specified range.
