Enumerable.Max Method (IEnumerable(Nullable(Int32)))

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

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

static member Max : 
        source:IEnumerable<Nullable<int>> -> Nullable<int> 

Parameters

source
Type: System.Collections.Generic.IEnumerable(Nullable(Int32))

A sequence of nullable Int32 values to determine the maximum 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 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(Nullable(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).

ExceptionCondition
ArgumentNullException

source is a null reference (Nothing in Visual Basic).

The Max(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 a null reference (Nothing in Visual Basic), this function returns a null reference (Nothing in Visual Basic).

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(Nullable(Double))) to determine the maximum 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.
