The Max operator returns the largest numeric element from a collection.

```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Prototype
{
    class Example
    {
        static void Main()
        {
            IList<employee> List = new List<employee>() {
            new employee() { id = 1, empname = "manoj", age = 18 } ,
            new employee() { id = 2, empname = "stephan",  age = 15 } ,
            new employee() { id = 3, empname = "sivil",  age = 25 } ,
            new employee() { id = 4, empname = "mohan" , age = 20 } ,
            new employee() { id = 5, empname = "johan" , age = 19 },
            new employee() { id = 6, empname = "Ram" , age = 18 }
               };

            var maxAge = List.Max(s => s.age);

            Console.WriteLine("Maximum Age of Employee: {0}", maxAge);

            Console.ReadLine();
        }
    }
    class employee
    {
        public int id { get; set; }
        public string empname { get; set; }
        public int age { get; set; }
    }
}
```
