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

.NET Framework 4.5

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

Namespace:  System.Linq
Assembly:  System.Core (in System.Core.dll)
```[ExtensionAttribute]
public:
generic<typename TSource>
static Decimal Min(
IEnumerable<TSource>^ source,
Func<TSource, Decimal>^ selector
)
```

#### Type Parameters

TSource

The type of the elements of source.

#### Parameters

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

A sequence of values to determine the minimum value of.

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

A transform function to apply to each element.

#### Return Value

Type: System::Decimal
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.

InvalidOperationException

source contains no elements.

The Min<TSource>(IEnumerable<TSource>, Func<TSource, 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 Decimal.

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.

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.
