MinBy<(Of <(<'TSource, TKey>)>)> Method (source, selector, comparer)
NamespacesMoreLinqMoreEnumerableMinBy<(Of <<'(TSource, TKey>)>>)(IEnumerable<(Of <<'(TSource>)>>), Func<(Of <<'(TSource, TKey>)>>), IComparer<(Of <<'(TKey>)>>))
Returns the minimal element of the given sequence, based on the given projection and the specified comparer for projected values.
Declaration Syntax
C#Visual BasicVisual C++
public static TSource MinBy<TSource, TKey>(
	this IEnumerable<TSource> source,
	Func<TSource, TKey> selector,
	IComparer<TKey> comparer
)
<ExtensionAttribute> _
Public Shared Function MinBy(Of TSource, TKey) ( _
	source As IEnumerable(Of TSource), _
	selector As Func(Of TSource, TKey), _
	comparer As IComparer(Of TKey) _
) As TSource
public:
[ExtensionAttribute]
generic<typename TSource, typename TKey>
static TSource MinBy(
	IEnumerable<TSource>^ source, 
	Func<TSource, TKey>^ selector, 
	IComparer<TKey>^ comparer
)
Generic Template Parameters
TSource
Type of the source sequence
TKey
Type of the projected element
Parameters
source (IEnumerable<(Of <(<'TSource>)>)>)
Source sequence
selector (Func<(Of <(<'TSource, TKey>)>)>)
Selector to use to pick the results to compare
comparer (IComparer<(Of <(<'TKey>)>)>)
Comparer to use to compare projected values
Return Value
The 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 IEnumerable<(Of <(<'TSource>)>)>. When you use instance method syntax to call this method, omit the first parameter.
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).
Exceptions
ExceptionCondition
ArgumentNullExceptionsource, selector or comparer is null
InvalidOperationExceptionsource is empty
