MoreEnumerableIncrementalTSource, TResult Method (IEnumerableTSource, FuncTSource, TSource, TResult) |
Note: This API is now obsolete.

static member Incremental :
sequence : IEnumerable<'TSource> *
resultSelector : Func<'TSource, 'TSource, 'TResult> -> IEnumerable<'TResult>
Parameters
- sequence
- Type: System.Collections.GenericIEnumerableTSource
The sequence of elements to incrementally process - resultSelector
- Type: SystemFuncTSource, TSource, TResult
A projection applied to each pair of adjacent elements in the sequence
Type Parameters
- TSource
- The type of the elements in the source sequence
- TResult
- The type of the elements in the result sequence
Return Value
Type:
IEnumerableTResultA sequence of elements resulting from projection every adjacent pair
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
The projection function is passed the previous and next element (in that order) and may use
either or both in computing the result.
If the sequence has less than two items, the result is always an empty sequence.
The number of items in the resulting sequence is always one less than in the source sequence.
