public:
generic <typename TSource, typename TKey>

<Extension()>
Public Function MinBy(Of TSource, TKey) (source As IQueryable(Of TSource), keySelector As Expression(Of Func(Of TSource, TKey))) As TSource

Type Parameters

TSource

The type of the elements of source.

TKey

The type of key to compare elements by.

Parameters

source
IQueryable<TSource>

A sequence of values to determine the minimum value of.

keySelector
Expression<Func<TSource,TKey>>

A function to extract the key for each element.

Returns

TSource

The value with the minimum key in the sequence.

Exceptions

source is null.

No key extracted from source implements the IComparable or IComparable<T> interface.
