Enumerable.Min(TSource) Method (IEnumerable(TSource), Func(TSource, Nullable(Single)))
Invokes a transform function on each element of a sequence and returns the minimum nullable Single value.
Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)
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, Nullable(Single))
A transform function to apply to each element.
Return Value
Type: System.Nullable(Single)The value of type Nullable<Single> in C# or Nullable(Of Single) in Visual Basic that corresponds to 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.| Exception | Condition |
|---|---|
| ArgumentNullException | source or selector is a null reference (Nothing in Visual Basic). |
The Min(TSource)(IEnumerable(TSource), Func(TSource, Nullable(Single))) method uses the Single 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<Single> in C# or Nullable(Of Single) in Visual Basic.
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.

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. |
