Enumerable.Min Method (IEnumerable<Nullable<Int32>>)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Returns the minimum value in a sequence of nullable Int32 values.
Namespace: System.Linq
Assembly: System.Core (in System.Core.dll)
Syntax
'Declaration
<ExtensionAttribute> _
Public Shared Function Min ( _
source As IEnumerable(Of Nullable(Of Integer)) _
) As Nullable(Of Integer)
public static Nullable<int> Min(
this IEnumerable<Nullable<int>> source
)
Parameters
- source
Type: System.Collections.Generic.IEnumerable<Nullable<Int32>>
A sequence of nullable Int32 values to determine the minimum value of.
Return Value
Type: System.Nullable<Int32>
A value of type Nullable<Int32> in C# or Nullable(Of Int32) 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<Nullable<Int32>>. When you use instance method syntax to call this method, omit the first parameter.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | source is nulla null reference (Nothing in Visual Basic). |
Remarks
The Min(IEnumerable<Nullable<Int32>>) method uses the Int32 implementation of IComparable<T> to compare values.
If the source sequence is empty or contains only values that are nulla null reference (Nothing in Visual Basic), this function returns nulla null reference (Nothing 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(IEnumerable<Nullable<Int32>>) to determine the minimum value in a sequence.
Dim grades() As Nullable(Of Integer) = {78, 92, Nothing, 99, 37, 81}
Dim min As Nullable(Of Integer) = grades.Min()
' Display the output.
outputBlock.Text &= "The lowest grade is " & min & vbCrLf
' This code produces the following output:
'
' The lowest grade is 37
int?[] grades = { 78, 92, null, 99, 37, 81 };
int? min = grades.Min();
outputBlock.Text += String.Format("The lowest grade is {0}.", min) + "\n";
/*
This code produces the following output:
The lowest grade is 37.
