resultSelector : Func<IEnumerable<'TSource>, 'TResult> -> IEnumerable<'TResult>
Parameters
- source
- Type: System.Collections.GenericIEnumerableTSource
The source sequence. - size
- Type: SystemInt32
Size of buckets. - resultSelector
- Type: SystemFuncIEnumerableTSource, TResult
The projection to apply to each bucket.
Type Parameters
- TSource
- Type of elements in source sequence.
- TResult
- Type of result returned by resultSelector.
Return Value
Type:
IEnumerableTResultA sequence of projections on equally sized buckets containing elements of the source collection.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Remarks
This operator uses deferred execution and streams its results (buckets and bucket content).
