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

var sortedDigits =
from d in digits
orderby d.Length, d
select d;

Console.WriteLine("Sorted digits:");
foreach (var d in sortedDigits)
{
Console.WriteLine(d);
}
}Result

Sorted digits:
