.NET Framework (current version)

Returns the minimum value in a sequence of nullable Single values.

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

Syntax

C++

<ExtensionAttribute>
Public Shared Function Min (
	source As IEnumerable(Of Nullable(Of Single))
) As Nullable(Of Single)

Parameters

source: Type: System.Collections.Generic.IEnumerable(Of Nullable(Of Single))
A sequence of nullable Single values to determine the minimum value of.

Return Value

Type: System.Nullable(Of Single)

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

Exceptions

Exception	Condition
ArgumentNullException	source is null.

Remarks

The Min(IEnumerable(Of Nullable(Of Single))) method uses the Single implementation of IComparable(Of T) to compare values.

If the source sequence is empty or contains only values that are null, this function returns null.

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(IEnumerable(Of Nullable(Of Int32))) to determine the minimum value in a sequence.

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, substitute the elements of the source sequence with elements of the appropriate numerical type.

Dim grades() As Nullable(Of Integer) = {78, 92, Nothing, 99, 37, 81}
Dim min As Nullable(Of Integer) = grades.Min()

' Display the output.
MsgBox("The lowest grade is " & min)

' This code produces the following output:
'
' The lowest grade is 37
