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

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

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

public static Nullable<double> Min(
	this IEnumerable<Nullable<double>> source
)

Parameters

source
Type: System.Collections.Generic.IEnumerable<Nullable<Double>>

A sequence of nullable Double values to determine the minimum value of.

Return Value

Type: System.Nullable<Double>
A value of type Nullable<Double> in C# or Nullable(Of Double) 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<Double>>. 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 is null.

The Min(IEnumerable<Nullable<Double>>) method uses the Double 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.

NoteNote:

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.

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.
