Enumerable.Max Method (IEnumerable<Int64>)

Returns the maximum value in a sequence of Int64 values.

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

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

Parameters

source
Type: System.Collections.Generic.IEnumerable<Int64>
A sequence of Int64 values to determine the maximum value of.

Return Value

Type: System.Int64
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<Int64>. When you use instance method syntax to call this method, omit the first parameter.

ExceptionCondition
ArgumentNullException

source is null.

InvalidOperationException

source contains no elements.

The Max(IEnumerable<Int64>) method uses the Int64 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.


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

      long max = longs.Max();

      outputBlock.Text += String.Format("The largest number is {0}.", max) + "\n";

      /*
       This code produces the following output:

       The largest number is 4294967296.
      */
