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

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

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

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

Type Parameters

TSource

The type of the elements of source.

TResult

The type of the value returned by selector.

Parameters

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

A sequence of values to determine the minimum value of.

selector
Type: System::Func<TSource, TResult>

A transform function to apply to each element.

Return Value

Type: TResult
The minimum value in the sequence.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<TSource>. 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).

ExceptionCondition
ArgumentNullException

source or selector is nullptr.

If type TResult implements IComparable<T>, this method uses that implementation to compare values. Otherwise, if type TResult implements IComparable, that implementation is used to compare values.

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.

NoteNote

This code example uses an overload of this overloaded method that is different from the specific overload that this topic describes. To extend the example to this topic, change the body of the selector function.

No code example is currently available or this language may not be supported.
