Min(TSource) Method (IEnumerable(TSource), Func(TSource, Int32))

Enumerable::Min<TSource> Method (IEnumerable<TSource>^, Func<TSource, Int32>^)

 

Invokes a transform function on each element of a sequence and returns the minimum Int32 value.

Namespace:   System.Linq
Assembly:  System.Core (in System.Core.dll)

public:
generic<typename TSource>
[ExtensionAttribute]
static int Min(
	IEnumerable<TSource>^ source,
	Func<TSource, int>^ selector
)

Parameters

source
Type: System.Collections.Generic::IEnumerable<TSource>^

A sequence of values to determine the minimum value of.

selector
Type: System::Func<TSource, Int32>^

A transform function to apply to each element.

Return Value

Type: System::Int32

The minimum value in the sequence.

Type Parameters

TSource

The type of the elements of source.

Exception Condition
ArgumentNullException

source or selector is null.

InvalidOperationException

source contains no elements.

The Min<TSource>(IEnumerable<TSource>^, Func<TSource, Int32>^) method uses the Int32 implementation of IComparable<T> to compare values.

You can apply this method to a sequence of arbitrary values if you provide a function, selector, that projects the members of source into a numeric type, specifically Int32.

In Visual Basic query expression syntax, an Aggregate Into Min() clause translates to an invocation of Min.

The following code example demonstrates how to use Min<TSource>(IEnumerable<TSource>^, Func<TSource, Int32>^) to determine the minimum value in a sequence of projected values.
