Lambda expression to get distinct records based on two columns in C#

In this program we are going use Lambda expression to get distinct employee list based on employee id and employee name (two) columns. 

using System;

using System.Collections.Generic;

using System.Linq;

namespace ConsoleApp1

{

    class Program

    {

        static void Main(string[] args)

        {

             var employees = new List<Employee> {

                new Employee { Name = "Surya", EId = 1, Salary= 4000 },

                new Employee { Name = "Infoware", EId = 2, Salary = 12.50M },

                new Employee { Name = "Surya", EId = 3, Salary = 1.15M },

                new Employee { Name = "Infoware", EId = 2, Salary = 2.00M },

                new Employee { Name = "Surya Infoware", EId = 5, Salary = 1000.0M }

              };

            var DistinctEmployNames = employees.Select(p => new { p.EId, p.Name }).Distinct().Count();

            Console.WriteLine("Distinct employee names {0} ", DistinctEmployNames.ToString());

        }

    }

    class Employee

    {

         public string Name;

         public int EId;

         public decimal Salary;

    }

}

Output:
