C# Enumerable Max(IEnumerable)
Description
Returns the maximum value in a generic sequence.
Syntax
public static TSource Max<TSource>(
this IEnumerable<TSource> source
)
Parameters
TSource- The type of the elements of source.source- A sequence of values to determine the maximum value of.
Example
The following code example demonstrates how to use Max(IEnumerable) to determine the maximum value in a sequence of IComparable objects.
// w w w.jav a2s. c o m
using System;
using System.Linq;
using System.Collections.Generic;
public class MainClass{
public static void Main(String[] argv){
Pet[] pets = { new Pet { Name="a", Age=8 },
new Pet { Name="b", Age=4 },
new Pet { Name="c", Age=1 } };
Pet max = pets.Max();
Console.WriteLine(max.Name);
}
}
class Pet : IComparable<Pet>
{
public string Name { get; set; }
public int Age { get; set; }
int IComparable<Pet>.CompareTo(Pet other)
{
int sumOther = other.Age + other.Name.Length;
int sumThis = this.Age + this.Name.Length;
if (sumOther > sumThis)
return -1;
else if (sumOther == sumThis)
return 0;
else
return 1;
}
}
The code above generates the following result.
