Min Method (IEnumerable(Nullable(Int32)))

Enumerable.Min Method (IEnumerable<Nullable<Int32>>)


Returns the minimum value in a sequence of nullable Int32 values.

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

public static Nullable<int> Min(
	this IEnumerable<Nullable<int>> 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.

Exception Condition

source is null.

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 null, this function returns null.

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

int?[] grades = { 78, 92, null, 99, 37, 81 };

int? min = grades.Min();

Console.WriteLine("The lowest grade is {0}.", min);

 This code produces the following output:

 The lowest grade is 37.
