Min(TSource) Method (IEnumerable(TSource), Func(TSource, Nullable(Decimal)))

# Enumerable::Min<TSource> Method (IEnumerable<TSource>^, Func<TSource, Nullable<Decimal>>^)

.NET Framework (current version)

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

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

## Syntax

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

#### Parameters

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

A sequence of values to determine the minimum value of.

selector
Type: System::Func<TSource, Nullable<Decimal>>^

A transform function to apply to each element.

#### Return Value

Type:

The value of type Nullable<Decimal> in C# or Nullable(Of Decimal) in Visual Basic that corresponds to the minimum value in the sequence.

#### Type Parameters

TSource

The type of the elements of source.

## Exceptions

Exception Condition
ArgumentNullException

source or selector is null.

## Remarks

The Min<TSource>(IEnumerable<TSource>^, Func<TSource, Nullable<Decimal>>^) method uses the Decimal 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 Nullable<Decimal> in C# or Nullable(Of Decimal) in Visual Basic.

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

## Examples

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.

Note

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.
