How to do a Select with Anonymous Types using LINQ in C#?

A simple select is classified under Projection Operators in LINQ. Below is a sample uses select to produce a sequence of the uppercase and lowercase versions of each word in the original array using LINQ Select statement

public void Linq() 
{ 
    string[] words = { "sUmMeR", "wInTeR", "aUtUmN" }; 
  
    var upperLowerWords = 
        from w in words 
        select new { Upper = w.ToUpper(), Lower = w.ToLower() }; 
  
    foreach (var ul in upperLowerWords) 
    { 
        Console.WriteLine("Uppercase: {0}, Lowercase: {1}", ul.Upper, ul.Lower); 
    } 
}

Result

Uppercase: SUMMER, Lowercase: summer
Uppercase: WINTER, Lowercase: winter
Uppercase: AUTUMN, Lowercase: autumn

Below is a sample to select to produce a sequence containing text representations of digits and whether their length is even or odd using LINQ Select statement

public void Linq() 
{ 
    int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; 
    string[] strings = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; 
  
    var digitOddEvens = 
        from n in numbers 
        select new { Digit = strings[n], Even = (n % 2 == 0) }; 
  
    foreach (var d in digitOddEvens) 
    { 
        Console.WriteLine("The digit {0} is {1}.", d.Digit, d.Even ? "even" : "odd"); 
    } 
}

Result

The digit five is odd.
The digit four is even.
The digit one is odd.
The digit three is odd.
The digit nine is odd.
The digit eight is even.
The digit six is even.
The digit seven is odd.
The digit two is even.
The digit zero is even.
