MinByExtensionMinByTSource, TKey Method (IEnumerableTSource, FuncTSource, TKey) |
Returns the minimal elements of the given sequence, based on
the given projection.
Namespace:
MoreLinq.Extensions
Assembly:
MoreLinq (in MoreLinq.dll) Version: 3.0.0
Syntax public static IExtremaEnumerable<TSource> MinBy<TSource, TKey>(
this IEnumerable<TSource> source,
Func<TSource, TKey> selector
)
<ExtensionAttribute>
Public Shared Function MinBy(Of TSource, TKey) (
source As IEnumerable(Of TSource),
selector As Func(Of TSource, TKey)
) As IExtremaEnumerable(Of TSource)
public:
[ExtensionAttribute]
generic<typename TSource, typename TKey>
static IExtremaEnumerable<TSource>^ MinBy(
IEnumerable<TSource>^ source,
Func<TSource, TKey>^ selector
)
[<ExtensionAttribute>]
static member MinBy :
source : IEnumerable<'TSource> *
selector : Func<'TSource, 'TKey> -> IExtremaEnumerable<'TSource>
Parameters
- source
- Type: System.Collections.GenericIEnumerableTSource
Source sequence - selector
- Type: SystemFuncTSource, TKey
Selector to use to pick the results to compare
Type Parameters
- TSource
- Type of the source sequence
- TKey
- Type of the projected element
Return Value
Type:
IExtremaEnumerableTSourceThe minimal element, according to the projection.
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).
Exceptions Remarks
This overload uses the default comparer for the projected type.
This operator uses deferred execution. The results are evaluated
and cached on first use to returned sequence.
