Question

I have this sample code:

string[] digits = { "zero", "one", "two", "three", 
  "four", "five", "six", "seven", "eight", "nine" };

var shortDigits = digits.Where((digit, index) => digit.Length < index);

Console.WriteLine("Short digits:");
foreach (var d in shortDigits)
{
    Console.WriteLine("The word {0} is shorter than its value.", d);
}

Is there a way generating same output only by using LINQ expressions?

Answer 1

I understand you are referring only to var shortDigits = digits.Where((digit, index) => digit.Length < index); I would have to think hard why you’d want to create such a monster if you are referring to generating the whole output with only LINQ

You could do the following to get the same output:

int i = 0;
var shortDigits = from d in digits
                  where d.Length < i++
                  select d;
