Enumerable.Max Method (IEnumerable(Of Int32))

Returns the maximum value in a sequence of Int32 values.

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

<ExtensionAttribute> _
Public Shared Function Max ( _
	source As IEnumerable(Of Integer) _
) As Integer


Type: System.Collections.Generic.IEnumerable(Of Int32)

A sequence of Int32 values to determine the maximum value of.

Return Value

Type: System.Int32
The maximum 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(Of Int32). 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).


source is Nothing.


source contains no elements.

The Max(IEnumerable(Of Int32)) method uses the Int32 implementation of IComparable(Of T) to compare values.

In Visual Basic query expression syntax, an Aggregate Into Max() clause translates to an invocation of Max.

The following code example demonstrates how to use Max(IEnumerable(Of Int64)) to determine the maximum value in a sequence.


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.

        ' Create a list of Long values. 
        Dim longs As New List(Of Long)(New Long() _
                                       {4294967296L, 466855135L, 81125L})

        ' Get the maximum value in the list. 
        Dim max As Long = longs.Max()

        ' Display the result.
        MsgBox("The largest number is " & max)

        ' This code produces the following output: 
        ' The largest number is 4294967296
