Max Method (IEnumerable(Int32))

Enumerable.Max Method (IEnumerable<Int32>)

 

Returns the maximum value in a sequence of Int32 values.

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

public static int Max(
	this IEnumerable<int> source
)

Parameters

source
Type: System.Collections.Generic.IEnumerable<Int32>

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

Return Value

Type: System.Int32

The maximum value in the sequence.

Exception Condition
ArgumentNullException

source is null.

InvalidOperationException

source contains no elements.

The Max(IEnumerable<Int32>) method uses the Int32 implementation of IComparable<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<Int64>) to determine the maximum value in a sequence.

System_CAPS_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.

List<long> longs = new List<long> { 4294967296L, 466855135L, 81125L };

long max = longs.Max();

Console.WriteLine("The largest number is {0}.", max);

/*
 This code produces the following output:

 The largest number is 4294967296.
