Syntax

C#

public static CompositeRange<T, TKey> ToCompositeRangeFrom<TSource, T, TKey>(
	this IEnumerable<TSource> source,
	Func<TSource, T> fromValueSelector,
	Func<TSource, TKey> keySelector
)

VB

<ExtensionAttribute>
Public Shared Function ToCompositeRangeFrom(Of TSource, T, TKey) ( 
	source As IEnumerable(Of TSource),
	fromValueSelector As Func(Of TSource, T),
	keySelector As Func(Of TSource, TKey)
) As CompositeRange(Of T, TKey)

F#

[<ExtensionAttribute>]
static member ToCompositeRangeFrom : 
        source : IEnumerable<'TSource> * 
        fromValueSelector : Func<'TSource, 'T> * 
        keySelector : Func<'TSource, 'TKey> -> CompositeRange<'T, 'TKey> 

Parameters

 

source

Type: System.Collections.Generic.IEnumerable(TSource)
Original collection.

fromValueSelector

Type: System.Func(TSource, T)
Callback to obtain a value for the From boundary.

keySelector

Type: System.Func(TSource, TKey)
Callback to obtain a value for the range key.

Type Parameters

 

TSource

The type of the values in original collection.

T

The type of the range values.

TKey

The type of the range key

Return Value

Type: CompositeRange(T, TKey)
A new composite range with keys filled from the original collection.
