Parameters
- source
- Type: System.Collections.Generic.IEnumerable<TSource>
The source sequence. - size
- Type: System.Int32
Size of buckets. - resultSelector
- Type: System.Func<IEnumerable<TSource>, TResult>
The projection to apply to each bucket.
Type Parameters

Return Value
Type:
IEnumerable<TResult>A 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
IEnumerable<TSource>. 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).
