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

Syntax

'Declaration
<ExtensionAttribute> _
Public Shared Function Min ( _
    source As IEnumerable(Of Nullable(Of Double)) _
) As Nullable(Of Double)

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

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.

Exceptions

Remarks

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 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.

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.
      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.
      */
