MoreEnumerableMinByTSource, TKey Method (IEnumerableTSource, FuncTSource, TKey) |
Returns the minimal element of the given sequence, based on
the given projection.
Namespace:
MoreLinq
Assembly:
MoreLinq (in MoreLinq.dll) Version: 2.10.0
Syntax public static 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 TSource
public:
[ExtensionAttribute]
generic<typename TSource, typename TKey>
static TSource MinBy(
IEnumerable<TSource>^ source,
Func<TSource, TKey>^ selector
)
[<ExtensionAttribute>]
static member MinBy :
source : IEnumerable<'TSource> *
selector : Func<'TSource, 'TKey> -> '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:
TSourceThe 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
If more than one element has the minimal projected value, the first
one encountered will be returned. This overload uses the default comparer
for the projected type. This operator uses immediate execution, but
only buffers a single result (the current minimal element).
