list comprehension

What is the equivalent of Python's list comprehension?

var li1 = new List<string> {"auto", "villamos", "metro"}; // ["auto", "villamos", "metro"]

var res1 = from s in li1 select s.ToUpper() + "!"; // ["AUTO!", "VILLAMOS!", "METRO!"]

Note that res1 is an iterator. If you need a list, convert it to a list: res1.ToList().

var res10 = from n in Enumerable.Range(0, 9) where n % 2 == 0 select n; // 0, 2, 4, 6, 8

Get the even numbers below 10.
