Introduction

We can use the object initialization features of C# to specify the anonymous class member names.

Demo

using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;

class Program//from  w  w w  .  ja  v  a 2 s . co  m
{
    static void Main(string[] args)
    {
        string[] names = {
          "Python", "Java", "Javascript", "Bash", "C++", "Oracle"};
        
        var nameObjs = names.Select(p => new { LastName = p, Length = p.Length });
        
        foreach (var item in nameObjs)
           Console.WriteLine("{0} is {1} characters long.", item.LastName, item.Length);
    }
}

Result

We specified a name for each member in the lambda expression and then accessed each member by name in the Console.WriteLine method call.
